  • Current limited charge relay

    Hi there, I am looking to charge an auxiliary windlass battery (130Ah lithium) that is located 35 feet away from my main bank (1030Ah lithium). My charging input will range from to 40 to 100 Amps, but I need to keep the wire size to a maximum of 6AWG. Do you know of any current limited charging relays similar to the "Mastervolt 83304002 Charge Mate Pro 40", which has a maximum output of 40A? Are there cheaper ways to achieve the same result? Thanks in advance!

    Sounds like a Current Limited DC power supply. Get a schematic for one, and scale the output stage for the amps you want.

    Nothing "off the shelf" that I know of.
