Lithium Polymer Batteries

BPI's rechargeable lithium ion polymer battery deliver high energy density and powerful performance, with platform voltages above 3.7V and continuous discharge rates of 10C-20C. They feature low self-discharge and superior safety thanks to aluminum-laminated soft packaging, which eliminates explosion risks. With a long cycle life exceeding 500 cycles and over 1000 for wide-temperature models they offer outstanding durability. Designed to operate from 20C to 60C, and up to 40C to 85C for extreme conditions, our batteries ensure stable performance in harsh environments. Lightweight and customizable in shape and size, they are produced on automated lines for excellent consistency and reliability.
