Hi emailed Sterling this:
I am buying this product, being recommended by fellow cruisers:
Alternator to Battery Chargers up to 130A | Sterling Power Products
Need to know one thing though. I will connect it to my Gel house bank 300 Ah. The start output -> will connect to both start battery and windlass battery via relay.
House bank (bank 1) + start battery (bank 2) + alternator + Sterling will be near each other.
Windlass battery (bank 3) 10 m away!
I want to use a not so fat cable to the windlass battery and raise the voltage near the windlass battery. One of the purposes of the windlass battery is that it is way cheaper than the 150 mm2 cable (40 m total!) required from the house bank.
Do you have a echo charger or "inverter charger" I can put near the windlass battery. Am I asking to much to also get temperature sensing (I will not get that on the start battery with your product) on that battery (perhaps a feature of the echo charger/inverter charger)?
Sterling start output -> relay -> start battery (short way no need for volt raise) AND to windlass battery (long way need ro raise voltage). Not sure about the relay AND an echo charger though.
What do you guys think, please?
Read the net a bit, can't seem to find my exact scenario.
