I wired the ebrake in and it works as the motor cut outs and I soldered the two white jumper cables together but no regen function at all. I'm running...

I took measurements again and I don't know if you call it cell 3 or 13 (don't know which end you start at)...

    The Cycle Satiator, universal charger for the enthusiasts

    Thanks Justin. I guess the voltage is limited by the 63 volt caps. So close to working for my pack yet so far away. Not to keep hounding the issue but I willing to bet that there are a lot people waiting for the higher voltage version to be released.

    Charger not charging

    I have a 60v 3amp charger that will not charge. I have checked both fuses and they are intact. When I plug charger in to wall the red Led will not light up. I plug my battery in and nothing. No fan or light. I read the voltage at the discharge cables and again nothing.

    Battery Troubles

    Those Samsung cells should not be out of balanced. I would say that it's a bms issue or the voltage needs adjusting in the charger. Genuine Samsung cells come out of the factory with the exact same voltage. Unless you have done a serious deep discharge the cells should all be balanced.
