Real life solar results
Just thought I’d post what I’m seeing. I have 400 watts of panels feeding 250 Ah (3000 watt-hours) AGM batteries. I ran them down fairly deeply, pulling 100 Ah of the 125 Ah feasible. Yesterday was ra...

Pulling that much out of any type of lead acid battery will significantly reduce it's life.
By lithium next time.
It really depends on how often he needs to deep cycle. Even at 80% DoD, he can get hundreds of cycles out of AGM's, so if he only deep discharges a few time a year, he may never see a payback on lithiums.
Pulling 100 Ah out of a 250 Ah battery is using only 40% capacity. Last time I looked, 50% is supposed to be the limit without damage. And we are talking about a true deep cycle battery, designed for solar applications, not a faux deep cycle "marine" battery.
