TAKING IT TO THE MAX, AGAIN! BigBattery’s 12V 3 kWh LiFePO4 OWL Max 2 battery takes all the incredible features you loved from our flagship OWL and OWL Max and adds even more capacity.
On top of brand new LFP cells, our advanced BMS, and 300A Fuse, the OWL Max 2 comes with an additional 418 Wh and 26 Ah of capacity, a sleek stainless steel casing, and an internal fire extinguisher. When you upgrade your RV’s power system with the OWL Max 2, you can cut the weight and space used by your battery bank in half. You’ll be able to provide more than twice the power in the same amount of space while lasting 4 times longer than the lead acid equivalent, all with ZERO maintenance!
With a compact, portable design and the ability to connect several units in parallel for a huge power system, this truly is one of our most versatile solutions. So if you’re looking for a battery that can not only bring you the power you’re looking for, but look good doing it, the 12V OWL Max 2 is the battery for you.

I had an amazing experience with the staff. They were super thorough with helping me find the right type of battery I needed and couldn't have been any nicer. Off the experience alone they've earned a long-term customer in me.
