The 31 has not been working very hard. 20 to 30 ah a night. Ive been urban stealth boondocking for the last 2 weeks. And not using biggest electric al draw, the laptop. No meanwell assist. Alternator and solar only.
It is not holding impressive voltages under this lighter duty use, but I had lowered max voltage to 14.7 in deference to agm many days. Today it spent hours at 15.3v while winding through the mountains and it appears to be rallying somewhat
However I suspect that getting 400 cycles from it might be unrealistic.
Well see.
