About the DIY battery, lots of peoples want the bigger battery, 720wh, 840wh, 960wh, the more the better,
but please note,
1. This is an electric assist bicycle, electric energy is only auxiliary and should not be the main force, Use your feet to move the pedals, not just sit there.
2. We talked with the bafang designers, they not suggest the bigger battery more than 500wh for M820 motor, That is, the full electric mode for two hours; high current output for a long time may cause the motor to overheat, which involves the effective conversion of energy of a motor, and they are still being resolved.
3. some info about BF F014, the infomations are old version, the newest version only change the battery mount.
