Shaped Cells

Shaped and Spec'd for Efficiency

Custom shaped batteries to fit into any and all available space in your product for maximum efficiency.

By utilizing Grepow's proprietary formula in our custom shaped cells, it will empower you against your competition.

Grepow's high discharge rate technology and fast charging capabilities will allow you to overpower your competitors and lower downtime between uses.


Grepow technology not only offers high discharge rates and fast charging but high voltage as well. We produce standard nominal 3.7V LiPo batteries and are also able to mass produce high-voltage batteries at 3.8V & 3.85V. The advantage is the increased energy density. Meanwhile, Grepow provide low temperature special shaped lipo battery for your request.


Small LiPo batteries that pack a punch. We are one of the best high-discharge rate battery manufacturers in the world. So, if max efficiency is needed, count on us. Our batteries are unbelievably small and extremely lightweight, but we don’t shy away from larger batteries. Got to give the big ones love too, since they do power a lot of things out there.

We produce shaped batteries based on the application, don’t need the punch but want fast charge or both Done. It’s all a matter of the applications and the special sauces. (Chemistry)

Low Temperature Shaped Battery

Grepow low temperature shaped battery operating environment in the low-temperature range -40℃ to 50℃. Compared with traditional Li-Polymer batteries, it has broken through the discharge temperature limits of -20℃ to 60℃.

High performance of discharge at low-temperature, reduce the internal resistance of the battery, and achieve the effect of high rate discharge. The lowest one is able to discharge over 60% efficiency @0.2C at -40℃, and discharge over 80% efficiency @0.2C at 30℃. Charge and discharge by 0.2C at -30 °C , the capacity is maintained above 85% after 300 cycles.

Can be widely used in cold climates and military products.With the ability to mass production, the cell consistency is good.
