This is a 48V 20.4AH lithium battery built by an experienced American lithium battery builder. It is made using the highest quality 18650 cells available, produced in Japan, by Panasonic. Not like the cheap cells used by Calibike batteries, which are made in China.

This battery includes a 30A BMS to balance and protect the cells, and charging and discharging power leads so you can custom fit to your needs. The battery is located in the USA and ships quickly - no more waiting weeks for a cheap Chinese battery! 

Includes full one-year warranty in the USA.
