Off-Season Sales

For obvious reasons, I take October – March off. If you are wanting to build/buy a Frankencooler during these months, I can possibly accommodate you – please contact me directly at frankencoolerusa@gmail.com.

Thanks, Bob

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.
