We decided to build a brand new battery storage for our pits...
We used a 48in Kobalt Job site box.
Has padded slots for 14 batteries, 7 chargers, Laptop, cell phone and power tool charging deck. We've added 2 large fans for intake air and 2 for exhaust for optimal temperature in the case.
Took us about 6hrs yesterday to complete. Come check it out in St. Louis next week!
