8D AGM Charge Settings correct?

Our new Victron MultiPlus Charger/Inverter has the capability of personalizing the battery charge settings, via a laptop and Victron software.

I have read that AGM batteries are a sensitive about being overcharged.

After what I have read, I came up with these number, as shown in the picture.

(absorption and Float voltage)

Thanks for all comments and suggestions.

We have 2 Northstar 8D 220ah House batteries.

They seem reasonable to me but no expert and learning myself. You might want to check at batty terminals during different parts of the profile to see what your battys actually see.
What I've learned from installing a Balmar SmartGauge monitor is what my V drop is from charger to battys. I don't have the capability you have but did choose a different AGM profile on my charger that gets me closer to recommended profile for my AGMs.

Suggest u look at the Marinehowto.com article on charger settings. Bottom line: get the parameters from your battery manufacturer & customize your Victronís settings Accordingly.

Use whatever Northstar says for those batteries.
