I'm charging my 800ah 12v LifePo4 battery bank with a Powermax 55a, 3-stage charger. The charger is integrated into a power center (30-55LK). When I energize the charger, it delivers 44-47a to the batteries (measured by Victron Smart Shunt).
Unfortunately, it hums pretty loudly, and then after approx 6 minutes it cuts off entirely. At cut off, it feels pretty hot to the touch, but the cooling fan never turns on. Do I have a dud on my hands, or is there some troubleshooting I could try?
Notes: I've set voltage output to 14.4 and tried both constant and three-stage settings. 120v power coming in via 10ga wire to main breaker.
