Our Story

From Chongqing Factory to Global B2B Partner

Chongqing Lianli Energy Co., Ltd. was founded in 2020 with a clear mission: provide high-quality LiFePO4 batteries directly from our factory to B2B partners worldwide, eliminating middleman markups.

We are not a trading company. We own and operate our production facility in Chongqing, China, with a complete manufacturing line covering cell sorting, PACK assembly, aging testing, and packaging.

Today, we serve over 50 RV modification shops, energy storage integrators, and electric vehicle manufacturers. Our monthly capacity of 5000+ units enables us to fulfill both small custom orders and large bulk wholesale requests.
