We completed testing on the solar charger for the Whippet Drywasher K2 Battery. We were very happy with the results in performance and usability. With the Whippet Drywasher, K2 Battery and solar charger, you can effectively prospect a remote area for days or even longer.
The charger is rated 15,4 volts, 30 Watts at 1.8amps, which can charge the K2 battery in as little as 3 hours. The unit folds from, 47" x 25" down to 13" x 7" and weighs less than 2 lbs.
Because the K2 Battery has intelligent circuitry built in, the solar charger can be connected directly to the battery without using a charge controller. This is both simpler and lighter.
This charger is very rugged, there is even a video of the unit being shot 12 times with a gun and it keeps on working at 90% efficiency.
We will be offering this charger as an accessory to the Whippet Drywasher.
