52 volts – The ultimate secret weapon for your 48 volt system. Compatible with most 48 volt motors and controllers – plug and play. You’ll enjoy more power while gaining more range. It’s win-win!!


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


This 52v 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, 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.
