Keystone RV & Dragonfly Energy sent us 2 new Lithium-ion batteries. Kelley was easily able to remove the old lead acid batteries and install the 2 new Lithium batteries. Dragonfly Energy batteries can be purchased from Keystone RV dealers. Keystone openers will have a dedicated technical support team at Dragonfly.
