This is a down and dirty lithium build using some LiFePO4 cells. I'm arranging these as 16s for a 48v pack. I found an old milk crate that works great to house the cells. I padded around the cells with plywood. Since there is no good airflow around the cells I'll be limiting my amps to prevent overheating.

I bought the cells from https://batteryhookup.com/ but sadly, they are already sold out. But there are always some cool batteries for sale. Use the discount code "DAVIDPOZ" for 10% off your order.

This battery needs a BMS. I'll be testing a brand new BMS for this build. It's called the Tiny BMS. There are many advanced features I'll be exploring.
