GDRV Extreme Lithium Package Review (TWO Mods for Better Generator Power)

We’ve spent the past year testing Grand Design RV’s Extreme Lithium Package (ELP) in real-world conditions, and in this video we’re breaking it all down — from installation and components to performance in every power scenario. We’ll cover how the system handles 50A hookups, 30A shore power, off-grid inverting, and generator use, plus the two simple wiring mods we made to unlock the full 6,000 watts from our generator. We’ll also touch on what happened to Volta Power Systems and how their tech lives on through Voltagen. If you’re curious about RV lithium power systems, inverters, solar, and off-grid camping setups, this is a must-watch for anyone considering the GDRV ELP option or planning their own lithium upgrade.
