     Step 1: Choose power cell .  Digital cell battery and Power Cell difference  Digital cell : overheat then life will be much shorted than power cell .  Theory can be charged 600 times , actually can only charge 200 times .  Discharge rate is below 1C  Power cell : low heating , support big discharge current , discharge current is 3C Step 2: Machine Pick up cells : Mainly check the Internal resistance and voltage , Two cells Internal resistance tolerance is 3 Milliohms Two cells voltage tolerance is 3 millivolt. Pick up the cells is to make sure the High matching consistency  ,avoid...

Good Welding and Bad Welding OF eBIKE Battery Good and strong welding keep battery always in balance status, batteryhas good and long using life. Bad welding will cause loose weld, battery will be not balance and always cut off, then most cells will die quickly.
