So am building a portable solar kit of two 5 watt solar panels to charge SLA's and 12 volt (10 x 1.2 AA rechargeables) pack. Based on the rated current stated is .32A X 2, I should come out with +/- .64A if connected in parallel. I measured the open circuit and its giving around ~.54A so there is a slight difference. I know the conditions are not always ideal e.g. direct sunlight and PV performance so would the .10A difference really impact the way the batteries are charged say at a constant 14V coming from the charge controller?
