PST-SBI-3112 is a componet that isolates and connects two batteries used in a system with what appears you have ..
the main battery with this product has charging priority...when the slave battery drops this componet connects the main battery to the slave..
when starting both batteries are connected..this device costs about 90.00.....
to avoid any surge damage always connect the battery grounds to the same ground stud...........also the loads being driven need fuses current limiters.. this device has a limit of 150amps @12volts dc...
