Here are new Topband 3.2v 25ah prismatic lifepo4 cells.

All cells have been 3rd party verified and tested to meet strict and consistent standards.

This calculation also takes into consideration the maximum continuous amp ratings of the cells.

Dimensions: 7 1/8 x 2 3/4 x 1 1/8

These batteries are perfect for many applications. M6 Nuts and busbars are not included. A lot of customers have used these for ebike packs too since they are small size. Especially when building batteries for high vibration applications it's important to use insulator material between the cells and lock washers on the busbar connections. Thin plastic sheets or barley paper are often used for insulator material. When you put 2 cells side by side you want something more than just the shrink wrap on the cells to prevent those cells from touching each other and causing a short. This goes for all prismatic cells with metal casing.
