Hi, I am looking at doing an install to charge an auxiliary AGM battery which will be at least a 5 metre cable run from the starter battery to aux. battery.
The model I am looking at is Victron Orion-Tr 12/12-9A
Will this model be sufficient? Also, is it better to mount the charger closer to the starter battery or closer to the aux. battery?
Hi @tristanhooft,
the Victron Orion-Tr 12/12-9 is a DC-DC converter and not a charger.
If you're looking for a DC-DC charger, then have a look at the Victron Orion-Tr Smart DC-DC charger series (isolated and non-isolated).
About mounting: the charger should be mounted close to the battery you want to charge, which is closer to the aux battery in your case.
Ah yes, my mistake. I’m looking at the 12/12-18 Amp charger now. One more question: will this also charge my starter battery when the voltage from the aux battery is brought above the cutoff voltage?
Thanks
