Batteries

[rmel]

Battery Tender is a good brand. I have one to keep my LFP 12V AUX battery topped off.

Should be fine keeping your pair of batteries in a float state. I'm a bit surprised you even
need a trickle charger -- assuming you open your Ground switch. Then you only have a
rather small internal-discharge, but that can worsen with age, and Temp.

But -- this trickle charger should be just fine.

Yeah just thought it was a good idea to keep them topped off all the time since it sits sometimes for a week+ plus it can get pretty cold here.

I'm starting to suspect Ill need new ones soon though. The NATO Odyssey batteries seem like the best upgrade but holy crap they are expensive, plus I wonder about the lack of a TPPL or AGM charging profile from the alternator. I've never understood how they push the AGM upgrades for many vehicles when they aren't charging at a high enough voltage.
