The more pedal assist (pedals assisting) – the longer the battery will last on a ride.
Each cell is rated to handle 35 amp continuous output! Built using a 60 amp continuous BMS for HIGH POWER applications.This pack can put out 60+ amps all day without overheating. Great for ALL CYC motors, BBSHD Ludicrous setups as well as BBSHD BAC ASI setups. Output wires are 10AWG silicone.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 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 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.
