jjrbus,

The best solution is a dc to DC charger. This will be automatic.

Second best is a solenoid that doesn't switch on until the voltage is 13.5 or higher.

I did opt for manual control of my twin 200 amp solenoids. But that was before dc to DC chargers were available at a cost that did not include your first born son.


You’re confused.
OP is taking aboot charging the start battery from shore power…. lol:S
