I'm converting the lead acid battery to LiFePO4 on my rv right now, just hooked up the Victron mppt 100/50 solar charger, Victron BMS 712 and a 2000w inverter connect to a brand new 200ah LiFePO4 battery for testing, all other chargers and loads are disconnected. I did few discharge tests with a hair dryer through the inverter, in 10 mins it used about 20ah battery, and it shows 80% battery remaining, I charged up again did the same test and got the same result. According to this the battery is only 100ah not 200ah, a 1700w device can only last 45mins, is there something wrong with the settings or the battery?
Thanks in advance.
