    48v 4.4ah DIY battery cutting out

    I have recently built a DIY 48v battery pack 13s by 2columns if that’s right. Basically each 18650 battery I’ve used is 2200mah. Making the battery 48v 4.4ah. I have added a bms for obv reasons and soldered my load and charge leads basically done everything by the book. However when connecting to my 1000w bike it turns on I can lift the wheel and hey presto it spins but when I sit on it (13stone) and go to pull away it cuts out, throttle turns off and nothing. I have to unplug and plug back in for it to come back on still with same problem when I sit on it and pull away! I’ve even restricted the motor to 250w with the same issue so... any ideas???
