50-70km for the 48v 1500w ebike motor
Note: The BMS Battery management system is the heart of any rechargeable battery pack. This is what determines how long your batteries will last, how much power they retain and how many usable recharge cycles you can expect. Before you buy any battery pack, be sure your BMS is properly engineered to work with your batteries to assure longer service life and safety.
