72 volts – The ultimate secret weapon for your high voltage, high amperage setup!

 

The more pedal assist (pedals assisting) – the longer the battery will last on a ride.

 

Our 20s 80amp continuous BMS with temperature protection will ensure stability within the battery pack and keep all 60 cells juiced up properly.

 

And don’t worry about having too many amps – your controller will only use the amps that it needs. Think of this pack as having amps in reserve if you should ever upgrade your motor/controller.

 

This 72v pack is built with a tight frame for better heat dissipation. Having too much empty air space actually acts as an insulator – trapping the heat inside the pack (think double-pane windows). Connections are made with solid Nickel strips and copper bus bars, spot welder to each cell. Each cell and each series is tested before assembly. The BMS will prevent over charging and will balance the cells after a full charge. It basically makes your battery as safe and as efficient as possible.
