Custom 18650 Battery

Since 2014, we have been working on custom 18650 battery pack with over 500 successful projects. From 18650 cell selection, we have long term business relations with top Chinese 18650 cell factories, like CATL, EVE, Roofer and Korean brand Samsung, LG, Sony with different nominal capacity, charge & discharge rate. 

We also design different PCM and BMS for its battery pack. It can be a smart protection board with RS485, RS232 communication protocol. The design of lithium-ion battery pack management system should consider overcharge, overdischarge, overtemperature, battery balance, etc.

When designing the structure, the insulation problem of the positive and negative electrodes should be considered. The environments faced by lithium-ion battery packs in different application fields are different. In terms of mechanical structure design, heat dissipation, heating, waterproofing, shock resistance, etc. should be considered
