100Ah Deep Cycle Batteries

100ah Lithium Batteries That Are Built for Australia, But Trusted by Explorers.

You could be navigating the open road in a fully kitted-out van, tackling rugged 4WD tracks, or cruising along the great Aussie coastline. It really doesn’t matter, iTech World's 100Ah deep cycle battery is built to go the distance. Designed and tested right here in Australia, these batteries promise reliable, efficient, and long-lasting power in even the harshest environments. From red dust and salt air to extreme heat and heavy rain, they won’t let you down. 

This range includes our popular LiFePO4 100Ah Deep Cycle Lithium Battery, which is a favourite among vanlifers and caravanners who need a waterproof, externally mountable solution. From the compact design that fits neatly under the bonnet or into canopy setups, or the IP67-rated protection, iTech World batteries are engineered for anything that you find on the road.

Why Trust iTech World to Power Your Adventure?
