I might just have to save the Schumacher for EQ sessions, as it seems every time now, to do sky high voltages.
I wanted to test SG again later today, and being partly cloudy, I plugged in, put it on the 12 amp setting, came back 90 minutes later and it was feeding the 31 11 amp at 16.4 volts, and I unplugged it. Not sure of the SOC at startup, as I unintentionally reset the amp hour counter last night.
The solar was then able to do about 4.5 amps and 4 amps was required to hold 14.8 initially. I took a reading on the 3 easy to access cells at this point. 1.250. Temps low 60's.
Envisioning Mex's pallet of warrantied 31's, I just rinse the hydrometer off and walked away.
A few hours later the solar had them at 15.3 taking 1.2 amps. Took another reading, 1.265 to 1.270 on the 3 easy cells.
Right now, under a 7.6 amp load( charging laptop battery), battery reading 12.38v. 9 amp hours from full according to my monitor.
12.29v under a 10 amp load( fridge kicked on)
Fridge kicked off, unplugged laptop, 2 amp load, voltage 30 seconds later 12.51v
Reading 10Ah from full
Turn off most everything. 0.3 amp load, 12.59v and climbing.
