More Highlights:
52 volts – The ultimate secret weapon for your 48 volt system. Compatible with 48 volt motors and controllers – plug and play. You’ll enjoy more power while gaining more range. It’s win-win!!
8.4 amp hours translates to 436 watt hours.
The more pedal assist (pedals assisting) – the longer the battery will last on a ride.
Our 14s 60amp continuous BMS with temperature protection will ensure stability within the battery pack and keep all 28 cells juiced up properly.
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.
