Battery Pack Picture
If you hope to assembled the battery pack by yourself ,pls pay close to below information
a. Select capacity, same capacities cells for one pack
b. Measure the voltage, same voltage cells for one pack(difference is under 0.02v per cell)
c. Measure the inner resistance,same IR cells for one pack (difference is under 1m Ohm)
All above steps are very strict to make sure the pack performance is perfect.
d. choose the excellence PCB with balance performance
