A bit oversimplified...but that is the reason to use an echocharger if one doesn't have a really sophisticated charger like yours.
Thanks Cam for taking the time to straighten me out..I'm sure it will help others as well with similar installations and the seemingly endless variables that get presented about it all the the way Simple works for simple minds like mine...

Re: Echo Charge drawbacks?

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.

Re: Echo Charge drawbacks?

So the Echo Charge only passes 15 amps? I'm using another combiner relay that's rated to pass 55 amps and since I have a 55 amp alternator it made sense to get that one. But a couple times now when checking the battery water I've found the house bank fine and the start battery dry. Looks like the combiner is passing too much current to the start side and boiling it out. So am I right in assuming the Echo is less likely to do that with only 15 amps passing over?
