Why Carry the GBX55?

Today's UTVs and trucks depend on complex electrical systems. Winches, audio systems, auxiliary lighting, GPS units, radios, and other accessories increase battery demand, while cold weather and long periods of storage can leave you with a dead battery when you least expect it.

The GBX55 gives you a dependable way to get back on the trail quickly without waiting for another vehicle or carrying bulky jumper cables.

Its higher output also makes it a smart investment if you own multiple vehicles with varying engine sizes.
