    How to make a lightweight battery

    I'd vote get the cheaper lower discharges ones. That's what Tesla did with load of ncr18650b. That way you only do shallow cycle and your pack last ages . My 200 cells pack of ncr18650pf built almost 3 years ago is still working nicely and with good range

    Should I go sensible or out right fun? BBSHD vs TSDZ2 350w

    I agree with d4ve that reliability and servicing is something you need to take into equation. The ones who never had issue are the ones who don't ride much. I'm a all weather heavy rider (700+ miles per month) and absolutely ALL my ebike parts failed at some stage. Some fail faster (bbsxx)...

    It's not that bad. But it has issue few minutes after riding on the rain. It can be either the throttle, the controller connectors, the controller itself or the motor wires....

    Controller stop working when it rains

    Helloi completely changed my kit and bought the very expensive phaserunner hoping for quality. But it stops when it rains... Again! It does 1 or 2 acceleration then it cuts. I need to restart it. I had to do that every 30s on my journey. Any idea what's wrong?
