C288 Battery Charger Config (or C24, 32)

[Remedy2]

I believe most of our chargers are configured the same: plugged into shore power the charger is to the house batteries only. Has anyone put the engine batteries in-line to charge and is there a benefit?

The other battery banks (two engine, one thruster) are charged via the ACR’s when the house bank is being charged by shore battery charger. Not sure how it works on the mixed chemistry (luxury edition), but that’s how my NW edition works.

OK that makes sense. I have a mixed bank- Lithium House; AGM thruster and Engine. Trying to solve a mystery- when on shore power the onboard battery charger quits charging. Its winter and I'll run the engines a bit to fully charge them and it starts charging again. Wondering if the ACR relay maybe bad?

I had a similar experience with our 288 LE. The charger stated that the house batteries were full and there was no amp draw.. I would run the boat for a bit and then see a draw on shore power (hence charging). After talking with Dakota and Balmar, and checking outputs with a multimeter- turns out house bank was full and Balmar monitor shunt was wacky. I did purchase the Kisae remote screen from DonRowe.com and mounted to port of the breaker panel- so alot easier to check battery charger status.

Interesting. I just had the shunt replaced and the Bluetooth module. Both had fried (no idea how). Only thing I haven't replaced is the ACR- I'm gonna search for that and see if maybe that's it. Thanks for the tip on the remote screen- that's helpful and a lot easier than crawling in the cockpit locker!
