All weather charging, in any condition! The waterproof GVB-8-WP charge controller with MPPT allows a lower-voltage solar panel to charge higher-voltage batteries. The GVB-8-Li-54.2V-WP can charge a 13S Li-ion (48V nominal) battery with a 36/60-cell solar panel. True MPPT delivers consistent performance! The advanced electronics inside the controller are encased in a proprietary potting compound making them ideal for ebikes, marine, golf carts, and electrical vehicle applications where they are exposed to the elements.

As a electric bike tourer this little device help me get across my state using solar along the way when a plug in wasn't available. It small, light, and has no fan.
