These batteries have never been cycled and they are rated for over 20,000 cycles and can be charged/discharged down to -30 degrees Celsius (-22 degrees Fahrenheit) temperatures. They were recovered from unused EV modules. Threaded posts have been laser welded so you can easily assemble with nuts. Every battery tested above 20ah.

Laser welded M5 studs were added for easy assembly and blue shrink wrap as well for insulation. It is recommended to use some type of insulation material between the cells. Plastic sheets or barley/fish paper is often used by manufacturers to provide adequate separation between the cells to make sure the metal casing doesn't touch and cause a short.

10 second Pulse discharge rate 500a (25c)
Dimensions 106 x 116 x 22mm
