230 Amp parallel set up for CPAP
I purchased a second 230 amp low temperature battery to run in parallel with one I got a couple of months ago. Primary use is to power our 12 volt system including a 90watt CPAP machine in our 5th wheel. This combo worked flawlessly and our nightly drop in voltage was less than .5 volts and about 25 AH. We have a 600 watt solar array which replenished the batteries daily.
