One 24V battery in place of two. The Lithium Rhino 24V 100Ah Marine Battery Kit replaces a heavy pair of 12V lead-acid or AGM batteries with a single 25.6V LiFePO4 pack, so you get all-day trolling power at roughly a third of the weight and none of the maintenance.

The Lithium Rhino 24V 100Ah Marine LiFePO4 Battery Kit is a 25.6V lithium iron phosphate battery built for 24V trolling motors, made by Lithium Rhino and available from Lithium Battery Supply, an authorized Lithium Rhino dealer. Every kit includes the battery, a 15A waterproof charger, a console gauge, an external power button, an on-battery color display, mounting hardware and the free Rhino app, and it is backed by an 8-year full-replacement warranty.

A traditional 24V trolling setup ties two 12V batteries together with a series jumper. That is well over 100 pounds sitting on your bow, four terminals to corrode, and a jumper cable to fail. This kit does the same job with one sealed 45.4 lb battery, one clean set of terminals, and no jumper. Less weight on the bow means better trim and easier access, and it frees up space for tackle and electronics.

Inside is lithium iron phosphate chemistry, the same reason your motor keeps its speed all day. LiFePO4 holds a steady voltage through almost the entire discharge, so your trolling motor pulls hard from the first cast to the last instead of slowly fading the way lead-acid does. You get 100Ah and 2,560Wh of energy, a 150A smart BMS watching every cell, and IP67 sealing built for spray, rain, dust and the pounding of rough water.

Who it's for

Anglers and boaters running a 24V trolling motor usually 55 to 80 lb thrust, who want to trade a heavy two-battery lead-acid setup for one lighter battery, hold steady power through a full day, and be done with acid, watering and corroded terminals. It suits bass boats, aluminum and multi-species boats, bay boats, skiffs and pontoons rigged with a 24V bow-mount motor.

What changes on the water

You take roughly 60 or more pounds off the bow, which helps the boat sit and run better. Your trolling motor keeps its speed from the first spot to the last instead of slowing down in the afternoon, so spot-lock and shoreline fishing stay strong late in the day. And you stop planning trips around a fading battery charge it overnight on the included charger and it's ready the next morning.

What makes it a strong upgrade

• One-battery 24V design, no series jumper, fewer terminals, simpler install than two 12V batteries.
• 2,560Wh of usable lithium power, full-day runtime for most anglers who mix cruising, spot-lock and shoreline fishing.
• 150A continuous BMS, plenty of headroom for common 24V motors, with built-in over-current, short-circuit, temperature and voltage protection.
• IP67 marine sealing, protected against dust and temporary water immersion.
• Complete kit, 15A waterproof charger, console gauge, external power button, on-battery color display and the free Rhino app, all included.
• 8-year warranty and US-based support, full-replacement coverage on the cells, BMS and electronics.

Why Lithium Rhino

There are cheaper 24V lithium batteries and there are bare batteries sold without a charger. Lithium Rhino sits in a different spot: a complete, marine-focused kit with the discharge headroom, sealing and support that hold up to real fishing use. Here's what stands behind it.

Discharge headroom that fits high-thrust motors

The 150A continuous BMS, with a 500A peak, gives more current headroom than many competing 24V 100Ah batteries that top out around 100A. That matters during spot-lock bursts and when a bigger 24V motor loads up against wind and current.

Built and sealed for the marine environment

An IP67 rating protects against dust and temporary water immersion — a step above the IP65 rating found on many competitors. The dual-layer ABS shell is made to take spray, vibration and the pounding of rough water.

A complete kit, not just a battery

The 15A waterproof charger, console gauge, external power button, on-battery color display and free Rhino app are all in the box. You can read state of charge three ways on the battery, at the helm, or on your phone which matters with lithium because voltage stays flat and a simple gauge can't tell you much on its own.

8-year warranty and US-based support

The battery is rated for 6,000+ cycles and a 10+ year life expectancy, and it's backed by an 8-year full-replacement warranty on the cells, BMS and electronics. As an authorized Lithium Rhino dealer, Lithium Battery Supply can help you with sizing, setup and any warranty claim directly.

Compatibility

This battery suits trolling motors built for a nominal 24V system, which generally means motors in the 55–80 lb thrust range on boats up to about 20 feet. Compatibility comes down to voltage and current draw, not the brand on the cowling, so always check the label on your exact motor before ordering.

Common 24V trolling motors

• Minn Kota: 24V versions of Edge 70, PowerDrive 70, Terrova 55/80, Riptide Terrova, Riptide PowerDrive and Ultrex.
• MotorGuide: 24V versions of X3-70, Xi5 80 and Tour / Tour Pro.
• Garmin Force, Lowrance Ghost and Ghost X, Rhodan HD: these are offered in both 24V and 36V. This battery fits only the 24V configuration and cannot be paired for 36V.
• Newport Vessels and Haswing: 24V models such as the Newport NV Series and Haswing Cayman and Protruar. Confirm your model's voltage and amp draw before connecting.

Boat types it fits

Bass boats, aluminum and multi-species boats, walleye boats, jon boats, flats boats and skiffs, bay boats and pontoons, anything running a 24V bow-mount trolling motor with room to mount the battery securely. Physical fit depends on your compartment dimensions, so measure before buying.

Boats commonly running 24V trolling motors

If you fish a Ranger, Skeeter, Nitro, Tracker, Bass Cat, Phoenix, Caymas, Triton, Vexus, Lund, Crestliner, Alumacraft, G3, Xpress, SeaArk, Lowe, War Eagle, Blazer, Falcon, Sea Hunt, Sportsman, Pathfinder, Hewes, Maverick or Carolina Skiff, among many others, there's a good chance it's set up for a 24V bow-mount motor that this battery can run. The battery isn't tied to any one boat brand; what matters is that your motor is 24V and the battery fits your compartment.

Boat and motor brand names describe compatible applications only. Lithium Rhino is not affiliated with, or endorsed by, these manufacturers, and compatibility should be verified for your specific boat, motor, wiring and charger.

Runtime

Runtime depends on how hard you push the motor. The rule is simple: divide capacity by your average current draw. The battery is rated for 240 minutes of reserve at a steady 25A draw, and the table below extends that to other loads. These are continuous-draw estimates under ideal conditions wind, current, boat weight, weeds and heavy spot-lock use will shorten them.

Will it last all day? For most anglers, yes. When the motor is used the normal way positioning, drift correction, shoreline fishing and spot-lock rather than wide-open running, a full day on the water is realistic. If you routinely run near full throttle in wind or current, estimate from your motor's maximum amp draw and consider whether a higher-capacity 24V battery fits your style better. Leaving roughly 20% in the tank rather than draining to empty also helps the battery reach its full cycle life.

Lithium vs AGM

The usual 24V trolling setup is two 12V AGM or lead-acid batteries wired in series. Here's how one Lithium Rhino compares to that traditional pair.

The short version: one lighter battery, more usable energy, steadier speed and far more cycles, with three built-in ways to see exactly where your charge stands.

Installation & Charging

Installing the battery

• Confirm the motor is 24V. Read the voltage on the motor label never assume it from thrust or model name, since many families come in more than one voltage.
• Measure your compartment. Allow for the 14.65 x 10.51 x 8.70 in body plus room for terminals, cable bends and access to the display.
• Remove the old bank. Kill shore power and all loads first, and photograph the wiring before you disconnect. The old series jumper between two 12V batteries is not used here.
• Mount it securely. Use the included hardware or a marine tray that stops the battery from sliding or tipping in rough water.
• Add circuit protection. Fit the breaker or fuse your motor maker specifies, as close to the positive terminal as practical. The internal BMS is not a substitute for a main breaker.
• Use the right cable. Tinned marine cable sized for your motor's current and run length, with correctly sized M8 lugs torqued to spec.
• Wire the gauge and button, then test. Route the low-voltage display wiring away from heat and sharp edges, then check polarity, torque, breaker and charger behavior before launch. Compare the app reading to the console gauge.

Charging

Use the included 15A waterproof LiFePO4 charger, it's matched to the battery and is the simplest correct option. If you use a different charger, it must be a 24V LiFePO4 profile that stays within the 29.2V limit.

• Do not use a 12V charger, it cannot charge a 24V battery.
• A two-bank 12V lead-acid onboard charger is generally not right for a single 24V battery unless its maker specifically supports that setup.
• Turn off any equalization or desulfation modes, which are for lead-acid and can apply the wrong voltage.
• Don't wire the battery straight to an outboard alternator, use a proper DC-to-DC charger designed for LiFePO4.

Care and storage

• Charge only with the included or another approved LiFePO4 charger.
• Don't store it fully drained; leave a partial charge and switch off loads.
• Keep it out of standing bilge water even though it's IP67 sealed.
• Check terminal tightness, cables and mounting periodically.
• Store in a dry, temperature-controlled spot for the off-season.
• Don't charge in freezing conditions unless the manual permits it the published temperature range covers discharge, so confirm the cold-charge limit before winter use.
