This battery pack is a niterider pro series 4x li-ion that I bought off ebay for a couple bucks. They retail for about $150 so I want to see if it's possible to fix this guy.
When I first got it, it charged/discharged just fine. The third time I tried to charge it, the LED status indicator never came on which led to to tear it down to find out what's going on.
On to the pics...
Batteries and driver
I assume this is the circuit protection?
I originally thought bad solder joints, so I did a **** poor job of quickly re-soldering the +/- and status wires.
Probed the batteries before the circuit protection
Everything probed after the circuit protection registers the same value (never mind the hard drive in the pic, I used it as a platform to hold the battery )
If I plug in the wall charger and probe again, the .43v goes to .52v and never higher.
Any idea's of what I should do, or if it's possible to fix?
