    Lyen 18 FET Controller Blown

    Hi there I bought a Lyen 18 FET controller last year and it worked out great. I upped my voltage to 92 (from 72) and according to Edward I only needed to replace the resister to and 400 ohms unit. Unfortunately my soldering job was no good and it blew 4 FETS and damaged some other circuitry on...

    48 volt BMS for 72 volt battery?

    I have a question...already have a 48 volt lifepo4 battery for my ebike. Adding more cells to make it 72 volts. Problem is that the bms only has 8 bms charging/monitoring wires (16- positive and negative) each pair going to 32 groups of cells...so each positive and negative wire wire monitors 32...

    HI guys I bought the Clyte HS3540 hub motor. I tested and even though i was not using alot of throttle, the axle spun on me, severing several of the phase wires. After completing repairs, including deburring the sharp edge in the slot where the wires go, it is not working. Nothing. I hooked up...
