Where To Buy It:
FAQ: “Can I charge my batteries by plugging this charger directly into a solar panel?”
It is not recommended to charge directly from any solar charger to your batteries without a battery pack, as the intermittent charging from clouds or coverage can lead to damaged battery capacity readings, whereas the battery pack is made to handle the intermittent charges without concern.
In other words: it’s always better to charge the battery pack, and then use the battery pack to charge your batteries. The recommended solar charger above comes with a great battery pack for just this purpose.
