Electric Scooter Battery 51.2V 40Ah 2kWh RS485 CAN Anderson 120A IP54

Compact High Power Battery
This 51.2V 40Ah lithium iron phosphate battery stores 2048 watt hours of energy in a compact SPCC steel case measuring 425 by 258 by 198 millimeters. Weighing only 28 kilograms, it is ideal for electric bikes, scooters, motorcycles, and small EVs. The integrated BMS protects against overcharge, over discharge, overcurrent, short circuit, and temperature extremes. RS485 and CAN communication enable seamless integration with vehicle controllers and chargers.

Core Specifications
Nominal voltage is 51.2V with 40Ah rated capacity. Cycle life exceeds 5000 cycles at 80 percent depth of discharge (1C charge/discharge at 25°C) while retaining over 80 percent capacity. Weight is 28 kilograms. Terminal type is 120A Anderson. Housing is SPCC steel with IP54 splash and dust protection. Communication interfaces include RS485 and CAN.

Discharge Performance
Continuous discharge current is up to 100 amps, suitable for powering 3000W motors and controllers. Pulse discharge current reaches 180 amps for less than 500 milliseconds, handling acceleration spikes and startup surges. Recommended voltage disconnect is 32V. BMS discharge cut off voltage is 39V with reconnect at 44.8V. Short circuit protection activates within 300 to 800 microseconds.

Charge Parameters
Charging uses the CC CV method with charge voltage range of 56.8V to 58.4V. Recommended float voltage is 54V to 55.2V. Standard charge current is 40 amps, while maximum charge current is 100 amps for fast charging. BMS charge cut off voltage is set to 58.4V.

Temperature Range
Discharge temperature range is -20°C to 60°C. Charge temperature range is 0°C to 60°C. Storage temperature range is -20°C to 60°C. BMS high temperature cut off is set to 60°C.

Communication and Monitoring
RS485 and CAN ports allow the battery to communicate with the vehicle controller, display dashboard, and charger. Real time data includes voltage, current, temperature, state of charge, and fault codes. This enables range estimation, performance optimization, and diagnostic alerts.
