If you thought the first generation of BigBattery’s OWL MAX was a powerful battery, get ready for the OWL MAX 2!

With the same great base features as the OWL, and all the safety and performance upgrades of our OWL MAX, this battery is already powerful… but then they added an extra 300 Wh of capacity, and didn’t have to sacrifice any space to do it! When you upgrade with the OWL MAX 2, you can cut the space and weight of your battery bank by more than half, allowing you to have more room for storage and greater fuel efficiency.

The BigBattery Owl Max 2 is the most advanced 12V battery they offer. A wide temperature range allows it to be discharged in below freezing temperatures for all you winter vacationers, and a Max Charge Current of 175A allows you to recharge in a matter of hours so you’re never held up by your battery system again. Plus, the OWL Max 2 has the same versatility with how you can connect your OWLs together so you can create as small or as big of a battery bank as needed.

If you’re looking to get outfitted with the latest lithium ion battery technology available today, look no further than the Big Battery OWL Max 2!
