The range is not huge, maybe 16-17 km. 25% left on the batteries and meter shows 11.1 km.
i did run it really heavy and had my kids onboard so thats extra 35kg
we did really steep hills and we run it in the trail so not really good test. but all that power i am happy whit the range and i can get more range by just dropping the current limit, weird thing is that the kelly seems to cap the amp at 78A, it is now at 90A limit.
charged it whitout balancing to see do they get out of balance and they dont so its safe to charge them once or twice whitout balacing. charging at 10 amps tops the batteries really fast.
last pic is charging whitout balancing
