The 100% New Cell Li-ion E-Bike Battery Mounted on Rear Rack is a high-quality, reliable battery designed for electric bicycles. The battery is made using 100% new cells with a chemistry of Li(NiCoMn)O2 18650. It is available in two different nominal voltages, 36v and 48v, and has a nominal capacity of 10-20ah.
The outer case of the battery is made of durable aluminum, and its dimensions are 257*150*147mm. The battery can be charged using a standard charge method, which involves a constant current of 0.2C and a constant voltage of 42V, with a 100mA cut-off. Alternatively, a fast charge method can be used, which involves a constant current of 0.5CA, a constant voltage of 42V, and a 100mA cut-off.
During use, the battery can be discharged using a constant current of 0.2C until the end voltage reaches 36.4V. The battery weighs approximately 3.5KG/4.5Kg and has a continuous discharge current of 20A, with a peak discharge current of 60A. The battery has a cycle life of 500 times with DOD80%.
The battery is equipped with a BMS (Battery Management System), which provides protection against over-current, over-discharge, over-charge, and short-circuit events. It also has a balance function to ensure that all cells in the battery are charged and discharged evenly.
The battery has a storage temperature range of -10-40℃, a relative humidity range of 45-75%, and a pressure range of 86-106KPa. This battery is a great choice for anyone looking to upgrade or replace their current e-bike battery.
