Please help to identify battery configuration

Hi all,

I doubt this is easy to answer, but perhaps someone would be able to help me with this; especially if they do own one of these themselves.

Here's the problem. The charging cuts off at 12v (which I doubt is the battery's full capacity). So I guess the charging circuit doesn't know when it's actually full.

The battery is listed as 38,000mAh but we all know that's not true.

When the charging cuts off, the battery level indicator only shows 3/4 LEDs, which is annoying. The product is poorly designed.

Here's how much capacity I've got out of it:

I got it up to 12v. Jump started my boxer 3 times. Took it back in to charge a Nokia Lumia via USB. Then connected the 12v output to a universal Li-Ion charger to charge a small 3.6v cell. The charging cut off halfway because the power bank fell to 11.5v. At this point the battery indicator shows 2/4 LEDs. I then used the cable clamps to draw 12v at 2.5amps to turbo charge a set of 4 AA NiMH cells which took 15 minutes.

At the end of all these the indicator dropped to 1 light.

I would like to charge it up properly using an external charger like the IMaxB6, however to use it I need to know the battery's chemistry and capacity.

Do the output wires look like balancing leads? The look a lot for a 3S1P.

Also, I'm guessing this is Li-Po.

Any advise would be greatly appreciated.

Thanks in advance.
