Ammo Box .30 Cal Battery Box

thingiverse

This is my 20AH LiFePO4 battery box panel specifically designed to slide into a .30 caliber steel ammunition box. It accommodates a 30A switched circuit breaker, a panel meter for monitoring the battery state, a panel meter for monitoring the charge voltage and current, power supply cooling fans, wide input voltage power supply, powerpole connectors for charge input and battery output, switched USB ports, and a DC socket. The power distribution PCB was custom made on my CNC machine and accommodates auto-resetable automotive circuit breakers and screw terminals. The original models are available in TinkerCAD at the following links: https://www.tinkercad.com/things/7skgvDnMWiN https://www.tinkercad.com/things/aij7RCkeB2j The panel was too long for my Prusa I3 MK2.5S, so it was split and tabs were created that are bolted together with four 3mm socket hex cap screws. The screw heads are below the side surface and do not interfere with sliding the assembly into the box. The text was too thick for my Prusa I3 MK2.5S, so it was thinned out and cut to size that are bolted together with four 3mm socket hex cap screws. The screw heads are below the side surface and do not interfere with sliding the assembly into the box.
