So @HarryN asked me to post a bit about my Rolls AGM experience.
I have purchased 3 sets of;
Rolls AGMs “S6-275AGM-RE
For a couple of Van builds & also my Off Grid Cabin.
I have had great success with these 6v AGMs as a 2 battery bank in series to make up 12vdc @ 250Ah.
The systems I use them on are very basic & simple & very conservative in energy use & design.
For my Promaster Van, I charge them by DC2DC alternator & I use a Kisae 1250.
For my Off Grid Cabin, I charge them by 600W solar array & Victron 100 | 50.
Why not LFP ? Well at the time I purchased these AGMs I had a saying for LFP & that is they are great except for the 3Cs;
Cost ( no longer a factor )
Charge Complexity
Cold
