A CPU monitors charging and shuts the charger off when the battery is full. A wake-up mode can reset and repair a battery after BMS cut-off and wake a low-voltage battery. The cooling fan runs while charging; overheating protection shuts the charger down above 65℃ (149℉).

The charger is intended for RVs, campers, solar systems, marine use, truck batteries, trolling motors, electric yachts, off-grid applications and home energy storage. Its 2-color indicator uses LED2 and LED1: 1. From 0%-90%, both are red; 2. From 90%-99%, LED2 is green and LED1 remains red as current decreases; 3. At 100%, LED2 is green and LED1 is off, indicating charging has stopped; 4.

In no-load/0V wake-up mode, LED2 is red and LED1 is off.
