You’ve Got Questions

I receive a lot of emails asking questions about my coolers so I have created a FAQ section at the top of the right column addressing many of the most common. If you don’t see an answer to your question, contact me at

Bioenno Lithium Batteries From Frankencooler

After using Bioenno lithium iron phosphate (LifePO4) power cells in my personal coolers, I was so impressed by their quality, performance, and price that I became a dealer.

Frankencooler is proud to offer these battery/charger combos at factory-direct prices in sizes perfect for our products.

Also, from this point forward, just like in our Blowbox Component Packages, every Frankencooler Major Component Package and AIR Battery Remote Major Component Package will include a power plug that mates with any of these Bioenno power cells.

Shop around – you won’t find a better battery at these price points, period.
