It turns out I spoke to soon. I thought all was well, but the battery is not taking a charge. I still have no idea how I would figure out whether the issue is the charger or the BMS. Anybody have any advice? Can I buy a matched BMS & Charger anywhere and just rewire the battery pack I have?

Ok, so I tried to take the battery apart this weekend, but I forgot about photos until it was too late. Sorry about that. That 20 pin connector really does have wires running to every single pin (it looks like its about 20, I did not actually count them). All of the wires connected to the...

I pulled this pic from their website, its a pretty good shot of the connector, and what I have to take apart. It should not be too complex, but I want to wait until I can have a couple of hours undisturbed so I can take it apart correctly.

I got my kit from Ampedbikes about 10 days ago and installed it on a KHS Urban-X bike, and I bought a 36V-10AH LiFePo4 battery from goldenmotor.com. The kit was complete and no issues at all with the installation. The wheel spins up to about 21.2mph unloaded, and me and my 195lb frame cruise...
