Cell performance directly dictates total pack reliability. We subject all incoming cells to thorough incoming inspection and automated sorting before integration into custom battery pack assemblies.
We source directly from manufacturer-approved sales channels, mitigating counterfeit risks and guaranteeing authentic, fresh-lot battery cells with verified batch certificates.
Incoming cells undergo stringent internal impedance (IR), open-circuit voltage (OCV), capacity matching, and mechanical dimension verification in ISO 9001 controlled facilities.
Our custom battery packs built with tier-1 cells comply with international regulatory safety standards, including UN 38.3 transport testing, UL 1642, IEC 62133, and ATEX/HAZLOC directives.
Our experienced battery engineers can assist you in selecting the ideal cell chemistry, form factor, and BMS protection system for your unique OEM project parameters.
