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.

What&rsquos your advantage compared with other suppliers?

a. High quality batteries: Our batteries are in enough capacity, and lower in RI, Before shipment, we will inspect the products and ensure the quality which are well approved by our clients. b. Better service: We always offer what our clients need. Reply client&rsquos questions timely. Supply best projects solution for clients. We ship out the products on time&hellip
