138Ah Battery
A 138Ah deep cycle battery is the sweet spot for serious tourers who need reliable power without the weight or cost of a massive setup. Whether you're running a fridge 24/7, powering camp lights and gadgets, or operating a portable camp kitchen, a 138Ah battery has the grunt to keep everything running between charges.
Our range uses proven AGM technology, which means they're fully sealed and safe to mount inside your cabin or canopy. No off-gassing, no maintenance, no hassle. They're built to handle the punishment of corrugated tracks and rough terrain, with vibration-resistant construction that won't let you down when you need it most.
You'll get up to 1800 cycles out of these batteries when used correctly, and they recharge faster than traditional deep cycle batteries. Run them with a quality battery charger or pair them with a DC-DC charger and solar setup for true off-grid independence. And if you're looking for even more capacity, linking two batteries together is dead simple with the right cables.
These batteries work brilliantly as part of a dual battery system or as a standalone portable power station when paired with a battery box. They're compatible with most AGM battery setups, and whether you're upgrading from a smaller 115Ah battery or stepping up from a 98Ah unit, the extra capacity makes a real difference on extended trips.
