2 + 1 battery charging???
I'm getting ready to use the long holiday weekend to install my solar system on my travel trailer. 2 X 140w panels, Bogart Engineering solar controller.... I just bought two AGM Group 31 12V dee...

PWM, 12v charging, 12v panels in parallel.
PWM, 24v charging, 12v panels in series.
yes, the abs V, float V and IUI is based on battery brand/type and other stuff is based on capacity/type. No need to try and find/program battery charging specs for listed batteries.
You've bought into bogart's engineering, others buy into their own or experiment or other's or even WFCO, go for it.
TABLE 4: Programmed values for each P22 charging profile number. See *NOTE below
All values are normalized to a “capacity” of 220Ahr. After placing a profile in P22, then change the P3
setting to your value unless your system has capacity=220 Amp hr.

There are a couple of pages of various batteries listed by make and model numbers with the appropriate specs for each.
