Battery Voltage drop under load
Is a voltage drop to 12.0V to be expected with a 21.3A load with a fully charged ~216Ah battery bank? I've never loaded the batteries that much before, so really have no idea what to expect. It...

Sun came out.
Tested Sp.Gr.
6V bat attached to + was fine: 1.274-1.277
6V bat attached to - was weak: 1.260-1.270
Equalized at 15.8 for 2 hrs. Lots of nice bubbles.
Broke the Sp.Gr. float trying to clean out a bit of rubber. grrrrr.
So no "after" Sp.Gr. #'s. In the past they've been pretty good though (all over 1.270) after equalization.
Disconnected the solar panels this time. Turned on the inverter and frig.
Same thing happens. About 265W draw at inverter, V drops to 12.0V at the batteries and holds. V pops back up to ~12.5V after removing the load.
Guess this is just normal for these batts.
