    EUY S4 controller

    The controller was rated for 23A so this should make it a 30A+ ish. I didn't have time to test the bike properly but it felt like it had bit more torque at take off.

    Battery pack on/off switch problem

    Ok, will do so. I am thinking of hooking up the battery to another controller also just to see if the same problem occurs maybe its a inrush issue as you mentioned before, to rule that one out.

    Battery pack on/off switch problem

    The tank battery i have works as it should. I actually made it dual battery system with one of those "battery blenders" The thought was using the upp pack for shorter rides then adding the tank for range, its a heavy beast.

    Battery pack on/off switch problem

    Yes upp sells both 60v and 70v whale batteries. I am pretty sure it's a 14ah pack when I opened the battery i saw unused cell holders.

    Battery pack on/off switch problem

    I have not really tried this pack under high load for a long ride to much snow and ice where i live right now. The display does show volts, with me on the bike it drops from 81,5v to 75-76v when taking off. I opend the pack and took a look at the cells, they are samsung.

    Battery pack on/off switch problem

    Ok, thanks for the reply. Well its one of those cheeper packs but i does take charge as it should and yes it does not turn on when the switch is in the on position. Guess i have to open the pack for further inspection.

    Battery pack on/off switch problem

    Hi, My 72V unit pack battery suddenly started to have on/off switch issue. I have to toggle the switch and turn on the bike in the off position at the battery then quickly toggle the switch to on and then everything works as it should. I am thinking this must be a bms issue or?? Thanks!
