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.

12 Volt Power Port

by on Apr.03, 2009, under Accessories

I’m probably not alone with respect to finding myself with a dead cell phone battery at inopportune times.  Being caught in this position when preparing to go out for a day of riding, prompted me to come up with a way to charge a cell phone using my motorcycle’s battery and charging system.

I was convinced that the “pig tail” (or “fused quick connect”) generally left connected to one’s motorcycle battery for use as part of a battery tender system, provided a handy means of connection to the motorcycle’s battery and charging system.  It was just a matter of coming up with a cable having that SAE 2 Pin connector at one end and a “cigarette lighter” style power port at the other.

Encouraged by discussion with those with whom I shared this idea, I set out to make these 12 volt power ports readily available to bikers with a desire to power their 12V chargers, etc.

After assembling and trying out a few prototypes, I contracted a manufacturer here in the USA to produce a large quantity of power port assemblies at a length that seemed like it would be popular with many bikers – just long enough to reach our saddlebags (I discuss use of this power port assembly in conjunction with saddlebags in a separate post).

This was a power port assembly from the initial shipment.
They were about 14″ long, with about 9″ of Black SPT-1 Cord (18 AWG conductors), which was shorter than anticicpated.
Right off, I was thrilled with the high quality SAE 2 Pin connector that our manufacturer turns out.  It’s sturdy, and the size makes it easily grasped.
Since then, the assembly has been lengthened, such that the overall length of the assembly is about 15-1/2″, with 11″ of Black SPT-1 Cord (18 AWG conductors).
We’ve gone through several hundred, and bikers seem to be very pleased with the current length – long enough to reach…yet short enough to make it handy and compact for easy storage.

Using the Bohemian Biker 12V Power Port x SAE 2 Pin Assembly

by on Apr.03, 2009, under Application

In the case of a bike with saddlebags, there is a pretty simple set up that I often use to charge my cell phone while I’m out on my bike.  I use a cable (approximately 12” long) with an SAE 2-prong connector at one end, and a “cigarette lighter” style power port at the opposite end.  I couple the SAE 2-prong connector end up with the matching connector on the “battery tender” pigtail left connected to my Road King’s battery.  Then I plug the 12-volt charger I bought to go along with my cell phone into the power port, and the other end into my cell phone.   There is just enough power port cable length to enable me to put the cell phone, charger, and power port connection in my saddlebag, leaving only a short length of exposed cable.  This set up works like a charm for me, and it has conveniently bailed me out of untimely dead cell phone battery situations many times.

The same set up could be used for charging many other portable electronic devices, keeping the device safely stored in your bike’s saddlebag.   A similar set up could be arranged using a backpack secured to your passenger seat, luggage rack, or gas tank, with sufficient cable length.  If necessary, some sort of conveniently sized bag (made out of leather, for example) could easily be suspended in a strategic location.

The 12 Volt Power Port x SAE 2 Pin assembly pictured in these photographs is what we call our “compact” model, since the body of the power port is relatively short in comparison to most I’ve seen.

Although I’ve experienced no problem closing my hinged saddlebag cover across the cable, I anticipate that will interfere with the rubber seal’s ability to do its job…and in the event of rain, water would make its way into the saddlebag.

When we were developing the design for the 12 Volt Power Port x SAE 2 Pin we have had manufactured, the ability to close a hinged saddlebag lid across the cable was taken into consideration.  I chose SPT-1 w/ 18 AWG conductors (vs. the heavier possibilities…SPT-2 /16 AWG) specifically with this ability in mind.
