Hi,
I’m not sure this really matters but just need a sanity check.
I’ve installed an Orion Tr Smart 12V/12V - 18A ISOLATED DC-DC charger between the two batteries in my small boat (A starter battery for engine only, and secondary battery for all the accessories - VHF/Chart Plotter/Nav lights etc).
I was just about to install a standalone switch between the L and H pin of the remote wiring - I.e. I chose when the Orion is on or off with an independent switch. But according to the manual I could just run a 12V+ from my starter battery isolator switch to the H-pin. Therefore the Smart charger is switched on as soon as I switch on the main engine battery isolation switch on (which is technically easier as it saves me buying a new switch).
Presumably both options are pretty much identical. Are there any pros or cons to each method?
Thanks in advance
Ziggy
