For charging I use a Powerfilm Solar R14 rollable solar panel that produces an operating voltage of 15.4, at 14 watts and 0.9 amps. This is quite adequate to charge the battery packs. Because I sometimes use different solar panels, I have a 7-amp Sunforce controller between the panels and the battery pack. …
