Software Over-Current Protection

When discharge current exceeds 200A, the discharge MOSFETs are TURN OFF, no current is drawn
from the battery. When charge current exceeds 40A, the charge MOSFETs are TURN OFF, no cur-
rent input to the battery.

Hardware Short Circuit Protection

When Discharge current exceeds 300A, the discharge MOSFETs are TURN OFF, no current is dra-
wn from the battery until you charge the battery.

LED Indication

A dual color LED can properly indicate the status of TI 12V 110Ah battery
