Lifepo battery compatibility question

Hi! I think I have an easy one that I just want to confirm. Current setup is 2x Renogy 100 watt panels to a SmartSolar MPPT 75/15 to 2x 100ah AGM batteries in parallel. The AGMs are getting up there in age (came with the camper) and I’ll be replacing them in the next couple months. Can I plug and play 2x lifepo batteries with that setup? 12v system. Using a Smart BMV712 to monitor.

Thanks!

Vince

Yeah, no problem. Just connect to the MPPT, go to Settings > Battery and choose the LiFePO4 preset. You will need to change the capacity setting on the BMV too.

First, thanks! So, the capacity thing should be the same, though - right? The AGM batteries are both 100ah (each) and I’ll be replacing them with 100ah batteries. The only difference is the chemistry (presumably?).


As far as the presets, is that pretty straightforward?


Trying to decide whether to replace before a month long trip starting in late June or wait until we get back. There isn’t an issue at the moment, just being a little paranoid. It wouldn’t be the end of the world to replace during if the need arises. The batteries are around four years old.
