I also worry about their charge voltages a bit. I'm still analyzing the charger when I can. I have not seen proper charge voltages yet but it seems to be doing it's job.
Sorry, I don’t know much about the specifics. I just plug them in and unplug after they’ve been “green” for a while.
I sometimes even remember to switch to AGM mode when connecting to the little batteries in ATV and mower. Hope that’s not too critical 😳

I have tried the repair mode but didn’t have much luck with it on failing batteries. Some reviews said that it works but . I can’t fault the charger though as the batteries I’ve tried it on weren’t in good shape.

If I figure out anything good, I'll be sure to share it.
They are all the same size physically, so the 15 amp won't be any bigger than the 5 amp.

Little update on the NOCO G10... It has been hooked up well beyond 24 hours now. I checked it yesterday, last night, this morning, this evening....It has a green light that slowly fades in/ out. That should be maintenance/ optimization mode. It's still charging at 14.4x volts. seems a bit odd as most would be float charging around 13.6 with occasional checks and optimization.

Charger isn't warm nor the battery, so i'm not too worried...just seems odd.

The Victrons should be here in a couple days. I have another identical group 31 X2 odyssey extreme I need to charge up and check. So I will see how the Victron does in comparison.
I just noticed the Victron's don't come with an inline fuse but they offer an accessory plug that does have an inline fuse...that's about silly. I was going to order come of the accessory plugs too. Oh well, I have some in line fuse holders I can splice in or can come up with a different solution.
Now that I'm looking...the supplied battery clamps don't either but they sell sets that do...WTF!


Anyway, I'm just trying to provide some useful info to any newcomers that come across this. Most probably won't even care.
