Sure, it's 80W, I think it has current limiting too. I need, however, to be able to soak up power quickly, more quickly than a 1.2AH battery should be charged. I have three motors, the largest being a gearmotor current-limited to 4 or 5A. They only run maybe 10% of the time tops but if I were only charging the battery at a tenth of an amp, it won't keep up with the demand and I'll be wasting the 1.8A my panels put out. I need to be able to jam current in and out quickly which is why the caps are perfect other than their ultimate capacity - which mainly comes into play late in the day when the sun's waning.
