This build is a 1.3 kwh battery inside an ammo can at 48 volts!
I'm using 168 lithium cells. These cells are called "18650" for the size. Each cell is rated for 3.6v and 2200 mah. This means each cell is about 7.92 watt hours of capacity. When we add them all together this ammo can contains about 1.3 kwh (kilo watt hours). I arranged the cells in a 12p14s for a nice 48 volt battery.
Inside the ammo can I included a 20 amp circuit breaker and a 60 amp BMS. This provides protection built right into the enclosure. By using a real military metal ammo can, we have fire protection.
I used a 20 amp circuit breaker to limit the discharge. This is in an effort to keep the heat from building up. However, the charge current should be half of this.
