Description
In stock and shipping now. The Lithium Rhino Marine series is a complete lithium upgrade for anglers and boaters who are done hauling lead-acid. Its LiFePO4 pack weighs a fraction of the batteries it replaces, delivers its full rated capacity, and sits in an IP67 sealed case with a smart BMS that protects the cells for thousands of cycles.
The Rhino guarantee
If the battery fails for any reason within 8 years, Lithium Rhino replaces it at no charge.
8-Year Warranty
10+ Year Life
6,000+ Cycles
App ConnectedDead batteries shouldn't decide when you head home. Replace hundreds of pounds of lead-acid with one sealed lithium pack built to run all day.
Serious technology, built to take a beating
Three reasons the switch pays off on the water.
Power for the whole trip
Offered as 36V 65Ah, 36V 120Ah and 24V 100Ah, so there's a size that covers a full day on the water for your setup.
Smart sleep modes
Light sleep kicks in after 30 idle minutes, and deep sleep after a further 7 days, so stored charge is still there when you launch.
Monitor it three ways
Read the full-color screen on the battery, the round gauge at the console, or the free Rhino app. A helm-mounted button turns the pack on and off.
Take a closer look.
A complete drop-in lithium conversion for your boat.
Marine performance
Grade A LiFePO4 cells managed by Rhino's own proprietary BMS hold a nearly flat voltage curve, so your trolling motor pulls just as hard at the end of the day as at the start.
Tough case, color screen
The marine-grade shell is designed for pounding, vibration and rough water. A waterproof full-color display on the case shows status at a glance, day or night.
150A smart BMS
150A continuous output, built-in monitoring and an 8-year full-replacement warranty put this pack at the top of its class.
Zero maintenance
There's no water to top off and no corroded terminals to clean. Install it once and spend your time fishing.
