Hello,
I am installing Lithium house batteries that are Solar charged on my boat.
House bank is separated from engine battery by a Orion DC-DC Tr smart 30Amp to prevent the alternator from overheating.
I would also like to be able to charge the engine battery from house battery. I understood that Orion DC-DC are unidirectional so I would need to add another one.
I started looking at this model Orion Tr 12-12 9A, which is the smallest one available. https://www.victronenergy.com/dc-dc-converters/orion-tr-dc-dc-converters-isolated#technical-information . This is the non Smart one, it does not seem to be a proper battery charger and only outputs a constant voltage.
Would it be OK if I configure it for a float LeadAcid voltage of 13.4V and leave it ON all the time ? Or is there a risk of overcharging and potentially damaging the engine battery this way ?
Should I consider a smart model instead which seem to have a proper charger algorithm ?
Thanks
Loic
