Everything you need to add capacity to your existing system is included: battery box, fiberglass tray, epoxy, explosion proof "off-1-both-2" master switch, wire, terminals and all the connectors. Even wire ties are included for a tidy, professional job. Add a group 24 battery from a local source and you've doubled your onboard power.

As an alternative to a second battery you might want to consider one of our solar panel kits pictured below. Rather than adding additional storage, add the ability to recharge the battery you already have.
