Would 2 BattleBorn 100ah Lithium Batteries Be Enough For 1,800W Inverter In RV?
Published 09/16/2025
Question:
I have two Battle Born 100Ah batteries. Would that be enough for the 1,800W inverter GP94XR?

Expert Reply:
Yes Jenna, two 100Ah Battle Born lithiums are a very good match for the 1,800 watt inverter # GP94XR. Each 100Ah 12V battery holds about 1,200 watt-hours (Wh) of energy (12 volts × 100 amp-hours). Since lithium can safely use almost all of its rated capacity, your two-battery bank in parallel gives you about 2,400 Wh of usable power.
To put that into perspective, most RV microwaves are in the 1,000–1,350 watt range when on max power mode. If you ran a 1,200W microwave for 30 minutes, that’s about 600 Wh consumed - only a quarter of your total battery capacity. That still leaves plenty of room for lights, fans, charging devices, or even a CPAP overnight.
What’s the main appliance you want to power with your inverter?
