FLAGSHIP MODEL! BigBattery’s 12V 2.17 kWh LiFePO4 OWL battery was designed with your vans and RVs in mind and serves as a benchmark for the quality batteries you can expect from BigBattery.

Our OWL is equipped with brand new LFP cells, which is the safest lithium chemistry available today. Plus, our advanced BMS guarantees you Over/Under Voltage Protection, Over Current Protection, and a Thermal Management System that affords safe charging and discharging within a wide temperature range, with a 300A Fuse to back it all up. Whether you’re a full time van-lifer or a boondocking enthusiast, the OWL can keep you powered
and prepared.

When you upgrade to lithium, you’ll see and feel the difference. The 12V OWL has twice the power, half the weight, faster charge times, and up to 4x as many cycles when compared to the lead acid alternative, all while requiring zero maintenance. Not only is the OWL cheaper than lead acid since you don’t have to replace your batteries every 2-3 years, but at $0.43/Wh, the OWL is one of the most cost effective lithium RV batteries in its class. Upgrade today and power your next RV vacation with the 12V OWL from BigBattery.
