The Electric Bicycle Rear Rack Battery Pack with Taillight is a rechargeable lithium-ion battery pack that is designed to be mounted on the rear rack of an electric bicycle. The battery pack comes with a built-in taillight for added safety during nighttime rides.
The battery pack uses 100% new Li(NiCoMn)O2 18650 cells and is available in two voltage options: 36v and 48v. The nominal capacity of the battery pack ranges from 10-20ah. The outer case is made of aluminum, which provides durability and protection against impacts and the elements. The battery pack’s dimensions are 257*150*147mm and it weighs approximately 3.5KG/4.5Kg.
The battery pack can be charged using either a standard or fast charging method. Standard charging involves a constant current of 0.2C and a constant voltage of 42V with a 100mA cut-off. Fast charging involves a constant current of 0.5CA and a constant voltage of 42V with a 100mA cut-off.
The battery pack has a continuous discharge current of 20A and a peak discharge current of 60A, which means it can provide high levels of power to the electric motor of the bike. The battery pack has a cycle life of 500 times with DOD80%, which means it can be recharged and discharged up to 500 times before it begins to degrade significantly.
The battery pack is equipped with a BMS (battery management system) that provides protection against over-current, over-discharge, over-charge, and short-circuit. The BMS also helps to balance the individual cells in the battery pack to ensure they are all charged and discharged equally.
The battery pack can be stored in a temperature range of -10-40℃ with a relative humidity of 45-75% and a pressure range of 86-106KPa. Overall, the Electric Bicycle Rear Rack Battery Pack with Taillight is a high-quality and reliable power source for electric bicycles that provides convenience, safety, and high performance.
