Hello,
i am building a portable LiIonbattery for my van (simple diy camping build). I want to build it into a tool box to make it portable.
I already have a MPT 7210a charger that will be inside the toolboxand i would like to be able to charge the battery without solar panelwhile i am driving.
Can i connect (i would use powercon connectors) it to my car battery?
Question: What kind of relay would i need to make sure it only charges when the motor is running to prevent my car starting battery from draining? I think it needs to be something like a voltage meter that opens a relay at the cars charging voltage when the motor is running.
