Competitive advantage
3,312Wh Nominal Energy
A nominal voltage of 73.6V and a nominal capacity of 45Ah give 3,312Wh of energy. At 27.6kg, the pack delivers roughly 120Wh/kg at pack level.
01
80A Continuous Discharge Current
The maximum continuous discharge current is 80A, equal to about 5.9kW at nominal voltage. The standard discharge current is 45A. Match both figures against your motor and controller ratings.
02
23S3P LiFePO4 Cell Layout
Twenty-three cells in series and three strings in parallel set the 73.6V platform. LiFePO4 chemistry is widely used in electric vehicle batteries for its thermal stability.
03
RS485, CAN and Bluetooth Communication
Choose the interface your project needs and we will confirm the BMS configuration with you before production.
04
Wide Discharge Temperature Range
The battery discharges from -30°C to 60°C and charges from 0°C to 60°C, which suits riding in cold and hot climates.
05
