I have. New Chinese 72v U004 battery with hopefully LG cells. I’m new to ebike I’ve had one 48v and I think I messed up the battery as it has short life now. What’s The best tips and tricks you all have? Is the Charge to only 80-90% true? Excuse my stupidity but what is the voltage of 80-90? What’s the lowest I can safely go on the battery in terms of volt? Should I wait until almost empty to charge? Or charge every ride? Sorry again for the noob questions but any help would be appreciated.?
