1. Quick Details of 12.8v 42Ah SLA replacement battery
2. BMS management system of 12.8V 42Ah lithium battery
Over current protection: The BMS will cut-off protection circuit if it is over current.
Low-voltage protection: When the battery is low voltage, BMS automatically close all output function. You need to recharge the battery.
Over-voltage protection: When the battery is over voltage, BMS automatically close all input. You need to disconnect the charger.
Overload protection: When output power or start power of device is too large, BMS automatically cut off the circuit.
Short circuit protection: When DC output protection, BMS automatically cut off the circuit.
Overheating protection: When internal temperature is over 149℉ or 65℃, BMS automatically cut off the circuit.
