Ryobi Dual Battery DC to AC inverter

Wanted to make a portable Inverter for camping trips, and already use a ton of Ryobi One Plus devices (lights, radio etc.) when camping. So i remixed this existing dual battery mount. Leaf spring contacts work perfectly as described in the source build. The battery contacts are set up in parallel for the added amperage. cannibalized a 150watt auto inverter, and soldered on a 24v to 12v dc step down transformer. For some added heat dissipation 2 fans were added.
