    OK, re-soldered the cap in correctly, charged it up, and everything worked fine.
    A week later I went to use it and nothing.
    I actually sat down to type this, got through the first sentance, tried it and it worked again. 10 minutes later, nothing.
    I'm inclined to take it apart, toss the POS PCB, and buy a new PCB to wire in.

    I'd bypass the PCB completely - 4S1P 2200ma pack like that should run your 1 XM-L on high for over 3 hours. That driver is going to be in the 2.5A neighborhood, according to my own experience, and what the folks on Dx that have posted in their forums.

    Take some rides, say 30mins, a day or 2 apart without recharging. Let it sit a couple days and fire it back up. Measure the voltage of each individual cell before and immediately after each ride. I'm wondering if you have a cell dumping out on you under load.

    If you do have a cell dying, cut it out and have a 3S pack - you'll still have a ~2.5hr of runtime.

    That's what I did.
    Seems to be fine.
