RELiON’s RB100-HP is a Group 31 12V, 100Ah deep cycle lithium-ion battery built for starting and cycling. The RB100-HP has increased peak amps for starting motors, electric start generators, and other high amp draw devices, plus, it doubles as a house battery, powering peripherals, accessories, and more.

The RB100-HP now includes six battery terminals versus the two on standard batteries, offering users more flexibility when connecting electronics to the battery. The battery includes an IP67 ingress protection rating, which completely repels dust and resists water ingress for up to 30 minutes submerged at 1 meter. Other improvements include an atmospheric vent added to the top of the case that equalises pressure while preventing contaminants from entering the battery; a glue channel to ensure IP67 seal; screw latched closure to ensure seal longevity, and tied a rope with handle guides that replace ultrasonically welded straps to improve durability.
