Thanks for sticking with me. I am searching for a web link that would help. The system is made by BOSS Battery Operated Shower System, the model is the top of the line XW 20 designed to be recharged by the vehicle battery
The pump is designed to be submerge in bucket of water, powered externally the BOSS 12 volt battery, but pump is not 12Volt, it appears to be 5 volt so I guess I am looking for a battery pack that would not burn out pump
