12 Volt Accessory Cable Kit Component Polarity and Amp Ratings

by on Jun.20, 2009, under Application

 

12V Accessory Cable Kit

Swapped emails with the supplier of our 12 Volt Accessory Cable Kits concerning the amp ratings of the individual component cable assemblies and decided to post the results.

Considering this kit is included with the Global Solar SUNLINQ line of Portable Solar Chargers (6.5, 12, and 25 Watt), the components are meant for relatively light amperage applications…mostly…charging handheld electronics. As I’ve discussed in other posts, there are other applications for which the components of this kit are suited.  For example, coupling a 12 volt cell phone charger to a Battery Tender Quick Connect using the power port cable assembly and in some cases the 8′ extension cable.

These two components fit nicely into this application because the SAE 2 Pin on the end of the Battery Tender Quick Connect basically replicates the SAE 2 Pin on the output of one of Global’s Portable Solar Chargers.  Specifically, the protected “female” socket side of the SAE 2 Pin connector on the end of the Quick Connect is “hot” (+) positive.  Therefore, the “exposed” male pin of the SAE 2 Pin connector on the power port assembly leads to the centerpost of the power port socket…which must be “hot” (+) positive.

Now let’s look at an application in which things don’t work out similarly well.  Someone might have the idea they’d like to couple the power plug assembly to the output of their Battery Tender…such that they may insert the power port plug into the cigarette lighter socket of a vehicle of which they’d like to maintain the battery.  NO GO!  Won’t work!  Think about it…  If the protected “female” socket side of the SAE 2 Conductor Connector on the  “Battery Tender Quick Connect installed on your motorcycle’s battery is “hot” (+) positive…the “exposed” male pin on the output of your Battery Tender must be “hot” (+) positive.

Now back to out power port plug – remembering we were saying above…the SAE 2 Pin end of these components is meant to be plugged into an SAE 2 Conductor connector with a “hot” (+) positive “protected” female socket.  So, we have a “polarity” issue here to which we must pay close, careful attention.  Stop and think thing through…thoroughly…before you start coupling connectors together. 

The power port plug has an integral 2 amp fuse, so that component’s amp rating is pretty evident.  This is ample capacity for many applications – charging most handheld electronics, etc.  When you get into attempting to power something like a portable air compressor, it’s a different story.  Even a tiny air compressor may draw 7 or 8 amps, or more.  So, this power port plug would not have the rating to be used in an application such as this.  In fact, even the heavier duty power port plugs we handle (stand-alone…without SAE 2 Pin)…are fused at 5 amps…which would still be less than an application such as this might require.  Obviously, power port plugs must be available for this application…because there are miniature compressors employing them…stretched to the limit as they may be.  

What about that 12 volt power port!  It’s rated at 7 amps max.   In most cases borderline unacceptable for the air compressor application we discussed above, but providing plenty of capacity for handheld electronics.  But, think about it this way…that Battery Tender Quick Connect installed on your motorcycle battery probably has a 7.5 amp fuse.  So, the 5 piece accessory kit’s power port cable assembly fits nicely into that parameter.

Heated gloves might be OK plugged into one of these power ports…but as always…check the manufacturer’s specifications.  Obviously, stacking up multple pieces of heated clothing is going to put you over the maximum amperage rating.

Speaking of heated clothing…often employing COAX connectors…we’re prompted to talk about the “male” COAX “barrel” connector x SAE 2 Pin adaptor that comes as part of the 5 piece accessory kit.  Once again…7 amps.  So, maybe OK for gloves…but not much more.  Now this brings me to an application that I discuss in another post – using this adaptor to facilitate the maintenance of your battery via the COAX “female” heated clothing pigtail you might have installed on your motorcycle’s battery.  I cannot condone this practice, but figuring that won’t stop some…here’s the problem.  It’s the same polarity problem.  Once again, the polarity is opposite what you need to couple the SAE 2 Pin end to the output of your Battery Tender.   

But…alas…I came up with an easy fix…a “rig” of sorts.  Again, I cannot condone this practice…and for that reason…I sell the components as a “do-it-yourself” kit.  Basically, I provide you with the components to assemble what I call a “Hot Socket” Adaptor.  That is, there is continuity between the “protected” female socket at each end.  Therefore, there is a “female” socket to accept the “hot” (+) positive pin of the SAE 2 Pin connector on the output of your Battery Tender…and the respective Adaptor conduct leads to a “hot” (+) positive “protected” female socket at the other end…to accept the “exposed” male pin of the SAE 2 Pin on the COAX cable.  Now, the male COAX end of the COAX Assembly has the correct polarity…and can be coupled to the “female” COAX end of the Heated Clothing pigtail installed on your motorcycle’s battery.  This does the trick for those that wish to avoid having more than (1) pigtail dangling from their battery.

About those Battery Terminal Clamps (component of the 5 piece kit)…  Same situation…  The “exposed” male pin of the SAE 2 Pin of this assembly leads to the red handled (+) poitive alligator clamp.  Therefore, opposite of what it should be…to be coupled to your Battery Tender output SAE 2 Pin.  This assembly carries a 15 amp rating, but remember you’d still be limited by the lower amperage rating of (for example) the 8 foot extension.

This being a post covering a lot of components, topics, and issues…I will no doubt be adding to it in the future…

SAE 2 Pin Extension Cable Assemblies

by on Apr.20, 2009, under SAE 2 Pin

SAE 2 Pin extension cables offer some flexibility by providing for distance between the power source and the load – a couple different models to meet the circumstances of various applications.  For example, the lighter model makes for easy routing “on the go”…say from your Battery Tender Quick Connect “pigtail” up into a tank bag or backpack.  Where the sturdier model might be more appropriate for applications warranting greater durability.

“Y” extension cables expand the possibilities with respect to power sources, as well as loads.  “Y” cables facilitate combining multiple power sources in “parallel” to provide more capacity.  On the other hand, they also allow you to distribute power to multiple loads.

Hopefully, that word “parallel” rang a bell from back in the day when you learned about “parallel” vs. “series” circuits.  So, here’s a little refresher for those that haven’t thought about electrical circuits for a while.

Series vs. Parallel Wiring of Power Sources

Although each battery, solar cell, panel or module has a rated voltage and amperage, they can be wired together in such a manner as to obtain varying results.

Series Circuits/Series Wiring or Connection of Power Sources

A “series circuit” is one in which the circuit components are connected “end-to-end” providing a single path for the flow of current through all the components.

Series wiring (or connection) of power sources is accomplished by connecting the (+) “positive” of one power source to the (-) “negative” of the next.

Wiring power sources in series will result in increased voltage.  When power sources are wired in series, the voltages are additive.  Power sources wired in series will provide a total voltage equal to the sum of voltages of each individual power source.

Wiring power sources in series does not result in increased amperage.  A series circuit will have the same current throughout the circuit.

Parallel Circuits/Parallel Wiring or Connection of Power Sources

A “parallel circuit” is one in which two or more circuit components are connected like rungs of a ladder, providing separate paths for current through each of the components.

Parallel wiring (or connection) of power sources is accomplished by connecting the (+) “positive” leads of the power sources together…and then (-) “negative” leads with each other.

Wiring power sources in parallel will result in increased amperage.  When power sources are wired in parallel, the currents (amperages) are additive.  Power sources wired in parallel will provide a total current (amperage) equal to the sum of currents (amperages) of each individual power source.

Wiring power sources in parallel does not result in increased voltage.  A parallel circuit will have the same voltage throughout the circuit.

So, back to the possible applications of our “Y” Extension Cable…

Basically, as I mention above…the “Y” Extension Cable would allow you to combine the power from (2) power sources.  That could be (2) batteries, (2) portable solar chargers, or a combination of the two, i.e., a portable solar charger and a battery.  The beauty of the portable solar charger and battery combination is that the battery provides energy storage, while the portable solar charger provides power generation.  There is the  benefit of the battery being there as a relatively “level” source of power (as long as the battery isn’t drawn down too low)…even while the passing of a cloud may impact the portable solar charger’s output.  Portable solar chargers usually have internal diodes to prevent the “back-flow” of power, during shading.

By-the-way, our Global SUNLINQ Portable Solar Chargers come with an SAE 2 Pin connector on the end of the output cable.  The component cable assemblies that make up the included 5 piece accessory kit, have SAE 2 Pin connector ends, as well.

SAE 2 Pin extension cables, in general…

Extension cables also provide flexibilty with respect to orientation…which can be of key importance in the case of  portable solar chargers.  The ability to not only reach positions of maximum sun exposure, but orient for maximum exposure is  critical to attaining the full power generating capability of portable solar equipment.

When it comes to maintaining the charge of a battery…on board anything from a boat, to lawn tractor, ATV, motorcycle, or anything else with a 12 volt battery…SAE 2 Pin extension cables can prove to be very handy.   They can allow you to plug the Battery Tender into a wall outlet (keeping the unit safe and secure…as well as out of the weather)…and then potentially reaching the battery…in a driveway, in a shed, etc.   Generally, we’re talking current levels of milli-amps…sometimes a little more than 1 amp…so these distances and conductor sizes aren’t an issue.

While we’re on the topic of current levels, let’s talk about wire sizes and amperage ratings.  The lightweight 8 foot extension cable that comes as part of the 5 piece accessory kit (available separately, as well), has 18 AWG conductors and is rated at 10 amps.  Basically black lampcord (along the lines of SPT-1…but not marked as such), this cable is flexible and easily routed.

The standalone 8 foot extension cable is jacketed with a black sheath, therefore of heavier weight…and not quite as flexible…but more durable.  This cord has 16 AWG conductors, but is rated at 10 amps, as well.

I’ll take up these topics with respect to the “Y” extension cable in a future post, along with a more in-depth discussion of it’s potential applications and respective current load implications.

In addition to being very careful with respect to the current loads vs. amp ratings and polarity of various cables and adaptor assemblies, it’s always a good practice to keep close tabs on charging batteries – checking connections, giving the cords a feel, often.

And…always following manufacturer’s specified procedures…including the use of safety glasses, and attention to the issue of vapors and need for proper ventilation.

Deltran not only produces a high quality Battery Tender, but provides sturdy cables, connectors and clamp assemblies.  Deltran Battery Tenders  also come with thorough instructions.  When it comes to battery maintenance equipment – it’s best to stick with an industry leader – for safety’s sake, as well as performance.  Considering both Harley-Davidson and BMW put their name on Deltran Battery Tenders, most people would no doubt agree…Deltran is the industry leader.

Global SUNLINQ Portable Solar Chargers

by on Apr.12, 2009, under Solar

Portable Solar Chargers offer the ability to “Capitalize on the Sun’s Energy” – they provide the means to generate electricity using the sun’s rays.  Pictured above are the members of the the SUNLINQ line of portable solar chargers manufactured by Global Solar.

Global’s portable solar chargers are widely used not only by military personnel in remote locations, but by many others in civilian applications, as well.  Any application precipitating the need to charge a battery/hand held electronics in the field (e.g., communication devices, photography equipment, or navigation equipment such as a GPS unit),  could potentially be addressed with a portable solar charger.

For the sake demonstration, here’s a potential scenario in which one of these folding (therefore packable) solar chargers could serve the motorcyclist.  Say you’re traveling on a motorcycle trip (or maybe you’re an expedition biker), and you’re spending your nights tent camping along the way.  Maybe through the night you’d like to be able to tap into your motorcycle’s battery as a source of 12 volt power for one thing or another – charging handheld electronics, etc.  Using one of these portable solar chargers…with whatever sun remains when you make camp…and then the sunshine available the next morning…you could be trickle charging your motorcycle’s battery back up to full power…even while still tapping into the power for the charging of the handheld electronic device.

Setting aside the above scenario, I’d like to be able to say that if you found your motorcycle’s battery “dead”…lacking the power to crank over the engine…miles from any services, as well as a 110 volt outlet and a battery charger…you have a solution here (obviously, there may be the possibility of getting a jump off another bike).  I’d stop short of saying one of these portable solar chargers would be the answer.  You would be able you to trickle charge your motorcycle’s battery, but I’d hesitate to say you could bring a “dead” battery up to a charge level that will facilitate cranking over the engine…in an amount of time that would suit your needs in a situation such as this.

CAUTION – Do not attempt to start a motorcycle, i.e., crank the engine over…while still connected to a solar charger!  There is not sufficient power generated by a portable solar charger to run a starter and start your engine…and..the amperage draw will overload the light conductors.  This will no doubt “blow” the fuse of a Battery Tender Quick Connect – if it’s of…or near…the proper value – usually 7.5 amps.

Over some period of time…(depending on such variables as the intensity of the sun, orientation to the sun, shading, and the parameters of your specific solar charger, etc.)…one of these portable solar chargers will “trickle charge” your battery.  They are often used to “maintain” the healthy charge level of a battery during periods of no, or minimal use…such as a vehicle left at the airport for an extended amount of time…or a boat with a bilge pump running from time to time.   Considering the sophistication of the electronics of a Deltran Battery Tender, I’d offer that one of these units is a much better choice for something like your prized motorcycle put up for the winter…if you do that!

Friends, these portable solar chargers were pivotal in my recognition of the common link between motorcycle battery maintenance equipment and the majority of portable solar equipment – the SAE 2 Pin connector.

When I became a Global Solar dealer and began handling their line of portable solar chargers and accessories, I soon noticed that the connector on the output of Deltran Battery Tenders and Global SUNLINQ Portable Solar Chargers was the same – an SAE 2 Pin connector.   This awakened me to a “blinding flash of the obvious” – not only could a portable solar charger be connected directly to a motorcycle’s battery via the fused “Quick Connect” (normally left connected to the battery), but this connector opened up a whole range of possibilities with respect to tapping into the power of a motorcycle’s battery and charging system.

Along with a Global Solar  SUNLINQ Portable Solar Charger comes a 5 piece accessory cable kit including:  12 volt power port, 12 volt power plug, and battery terminal clamp cables, as well as an 8 foot extension and a COAX “male” 2.5 mm barrel connector adaptor.  The 5 piece accessory kits alone facilitate a wide range of useful operations.

For example, the 12 volt power port x SAE 2 Pin connector cable can be used to access 12 volt power for a cell phone charger.  The 12 volt power plug could be used the trickle charge a motorcycle battery off a vehicle with a 12 volt battery and power port.  The battery terminal clamp cable could also be used to trickle charge a motorcycle battery off the 12 volt battery of another vehicle.

Since the components of these accessory kits can be indespensible on their own, we make them available through our eBay store (see link below).   Through our eBay store we also make available a heavier, more durable 8 foot extension, as well as a “Y” cable which facilitates either “dual input” or “dual output”.  In addition, we make the Deltran “Quick Connect” with integral 7.5 amp fuse and 5/16″ ring terminals available there.  For those applications where less capacity is required, there is a generic battery “quick connect” with an integral 3 amp fuse and 1/4″ ring terminals.   25 foot extension cords with SAE 2 Pin connectors are available for applications involving greater distances for access, or positioning (for example, orientation to the sun for maximum exposure).

For several years, we’ve been providing customers all over the world with access to Global solar chargers, as well as related equipment.

12 Volt Accessory Cable 5-pc Kit w/ SAE 2 Pin Connect

by on Apr.05, 2009, under Accessories

12V Accessory Cable Kit

12V Accessory Cable Kit

This handy accessory kit is comprised of 5 cable assemblies with SAE 2 Pin connect.  The kit includes: 12V Power Port, 12V Power Plug, Battery Terminal Clamps, 2.5mm “male” COAX adaptor, and an 8 foot extension cable.
These cable assemblies can be indispensable.  Coupled with the necessary 12 volt charger, they can facilitate the charging of a cell phone and other electronics.  They can also facilitate the trickle charging of a 12V battery.
The SAE 2 Pin end of these assemblies is meant to be connected to a “power side” SAE 2 Pin connector leading from a power source, i.e., one with a hot (+) positive socket.  In other words, the exposed “male” pin of the SAE 2 Pin connector on the end of these assemblies is meant to be hot (+) positive.
The power port cable assembly, for example, has the conductor leading from the exposed “male” pin of the SAE 2 Pin leading to the (+) positive center post within the power port.   The power port plug assembly, similarly has the conductor leading from the exposed “male” pin of the SAE 2 Pin leads to the (+) positive center post  at the end of the power port plug.
Special attention is required with respect to the battery terminal clamp assembly.  The fact that it is wired similarly…(making it useful for trickle charging, etc., when connected as described above) …makes it unfit for use connected to the output of a Battery Tender.  Here’s why – the SAE 2 Pin connector at the end of a Deltran Battery Tender output has a (+) positive exposed male pin to match up to the SAE 2 Pin of a properly installed Deltran fused Quick Connect…which will have a hot (+) postive female socket.
These are light duty 12 volt cable assemblies, as indicated by the 2 amp fuse integral to the power port plug x SAE 2 Pin assembly.
