12v from 24v Battery Bank ?
With two 12vs in series and the 24v charger on the other two posts, can you draw 12v at the same time as they are being charged at 24v, from the pos and neg of just one of the batts? If so, will th...

Nope. Just thought of it :) Anyway with 24v charging on a 24v battery is everything the same as 12s except half the amps? Same charging profile, SOC vs time etc?
If so it would be easy to compare results. With my 230w panel and MPPT I was getting 15.5a in the Spring and 13.5a in the Summer. With PWM I should expect 14.5a all the time based on my 130w having 8.2 Isc. (which I got)
However, the Isc of the 230w panel is 8.3 and in the summer I often saw 8.4 or so. (Isc goes up with heat) So since I get Isc with a 12v panel I should get Isc with the 24v? and is 8.3a worth 16.6a in 24v language?
I notice that the 230w and the 130w have about the same Isc, so it is not twice really. Confusing.
I would take the 16.6 worth instead of 13.5 if that is how it works.
