Rogue MPPT, 490W and charging mysteries
Now that we were finally all in one place - me, Rogue 3048 and my rig - it was time to have some fun. 1)Battery: old starter, tested beyond dead, plates above the water. No wonder, 8 months in Mex...

BFL, fancy controller I need to learn how to use yet, if you followed the thread.
Batteries were sitting there 8 mos in warm weather. In fact, 10 mos counting from the day of purchase In January, though it was cooler then. And for some time before I bought them. And were never charged during those ~10 mos, and went down to ~60% judging by Deka numbers. This is AGM, they should be able to take such an abuse. Though 60% is exactly the line that UPG manufacturer warns not to cross, or "irreversible loss of capacity may happen". Deka, btw, have identical self-discharge chart, don't remember if the same warning. Will see. Let them float.
