Hi
I recently decided to add a Smart BLUE IP76 25a 120VAC charger to my off-grid setup.
I was looking at the history this week and noticed in the Smart BLUE IP67 charger my 210aH GC2 12v battery bank is listed as a 103aH battery! Being that it’s 2x 6v in series and reads correctly as a 12v by the system (and I double checked the connections) it’s not an issue with the series part (unless the series cable has too much resistance; it's a 6AWG I think?), and I checked the physical connection myself of course.
So I have a 25a charger that is only treating the bank it's charging as having half the capacity. Could it be the bank is nearing the end of it's usable life and has too much internal resistance? Or that I regularly only use about 40% (sometimes 50%) of the capacity?
I checked everywhere in the app and didn’t see a setting to change the aH capacity of the bank being charged by the BLUE IP67.
I have NOT networked it to the rest of my system (MPPT’s and BMV712), preferring to keep things as simple as possible.
Q: What's going on here with the incorrect AH reading of the battery it's charging?
