I have two 12v 100ah lifepo4 batteries in parallel (50a max thru the BMS) which I want to use for an inverter. Most of the stuff in my van is 12v, but I’m thinking of AC to run some tool chargers (makita, hitachi, etc) and a 24” tv with a DVD player. My thought is to get a 1500 to 2000w inverter...
