FAQ1.How to choose a right model
---a. confirm the size of the battery
b. confirm the capacity,voltage of the battery
c. confirm if you need protect PCB or not
d. confirm the terminal of battery,lead with wire or connector
2. Can you explain in detail how you match cells for a battery pack before you assembling the pack?
----We will do the following things before assembling the pack:
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.
