    The only lag I'm seeing is when I stop pedaling. The motor continues to run of a bit.

    BMS terminal clarification

    Thanks for the schematic. It would all fall into place if the new bms had a "C" charge terminal and if it showed what to do with the red + and black- wires on either side of the sence connector.

    BMS terminal clarification

    Sorry I don't see a schematic in plain view. I don't understand red wire for top and black for wire bottom. What is top and what is bottom? How would I know if there is no charging mosfet? Then the only thing is if you look close in the second pic there is a red and black wire on either side...

    BMS terminal clarification

    Presently the B+ heavy out put is not connected to the bms. It comes out the pack to the main battery connection. My confusion is where the Neg - charge wire is suppose to be connected on the new bms And what do I do with the small red+ and black- that is currently on either end of my sence...

    BMS terminal clarification

    I need to swap out a bms because of bad fets. The new Bms has terminals marked the same as the old. The B- "negative battery". P- "negative battery output" and the white sence terminal locations I understand. The ones on the end marked B+ B+ P+ P+ I don't know what goes there. The only wire...

    I can easily unplug the bms, but I will monitor it more closely next winter. I took it out for a good run with no issues.

    Homemade battery cases

    My 36v 20ah battery fits the 50 cal. ammo case very well. I use it for charging only. I think you could mount it to a bike with some added padding around the battery.. I have a dedicated battery box mounted to my columbia trike. I also was concerned with puncturing the shrink wrap on the...
