The EarthX ETX680C is fully regulated by an integrated battery management system (BMS) that protects the battery cells from overcharging, deep discharge, short circuit and excessive temperature and ensures that the state of charge of the cells is balanced. The battery is designed for 400ci engine power / 60Amp alternator.

The ETX Series starter batteries also feature redundant electronic circuitry and an LED indication of battery faults. The fault indicator can be connected to an EFIS or linked to a 12 volt LED indicator on your control panel to alert you to the battery's state of charge and health.
