Ultra Thin Battery

Ultra-thin characteristics

Grepow has been researching developing and manufacturing batteries for more than 20 years, and Grepow has developed the ultra-thin LiPo batteries. We can now offer special shaped batteries from 8 mm to as thin as 0.4 mm. The biggest characteristic of this ultra-thin battery is that the thickness of the whole battery can be less than 1 mm, which is as thin as paper, with long cycle life and low self-consumption.

Flexible support on custom solutions
