RELiON® Battery Unveils New RB100-HP Lithium Starting Battery

January 25, 2023
The enhanced battery is the first lithium-ion starting battery to be evaluated and approved for use with select Mercury outboards

Menomonee Falls, Wis. (January 25, 2023) – RELiON® Battery, a global leader in the development of lithium batteries, today announced the launch of its enhanced RB100-HP lithium battery, a Group 31 12V, 100Ah deep cycle lithium-Ion battery built for starting and cycling of marine and RV applications.

"We are happy to offer users an enhanced version of our RB100-HP battery and continue to provide the power they can rely on," said Eric Lindquist, VP and General Manager, Power Systems at Navico Group. "Our talented product team was thoughtful in the development of this battery, not only in enhancing the features, but also making sure it met all the specific requirements needed to be approved for use with select Mercury outboard engines."

New RB100-HP Dual Purpose 6 Terminal Lithium Battery

The new RB100-HP has increased peak amps for starting motors, electric start generators, and other high-amp-draw devices. It also doubles as a house battery, powering peripherals, accessories, and more. The new enhanced version features six 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 equalizes 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.

One of the most exciting benefits of the new RB100-HP Battery is that it is the first starting battery to be evaluated and approved that meets all the requirements for use with approved Mercury outboards. The models approved for use with the RB100-HP include:

  • 2.1L 75‑115hp FourStroke, Pro XS® and SeaPro™
  • 3.0L 150hp FourStroke, Pro XS and SeaPro
