Hello,

I have a friend who wants an electric bike, but I'm concerned over the maintenance and early death... how can we have a battery working for years and that can:
- Be used frequently until depletion (automatic cut off)
- Being charged max without consideration on time
- Weather proof, can be parked outdoor on the rain

Is there a BMS allowing max protection? Most of them aren't really good and will kill the battery easy if user frequently use it to max depletion for all rides.
