Trolling Motors Batteries

A lithium trolling motor battery changes how a fishing day ends. Instead of thrust fading by mid-afternoon, Vipboss 12V LiFePO4 batteries hold a steady voltage until they are nearly empty, so the motor feels the same on the last drift as on the first cast. This collection brings together three 12V deep cycle marine batteries, 105Ah, 210Ah and 320Ah, that cover everything from kayaks to bass boats running 24V or 36V motors.

Why Anglers Are Moving From Lead-Acid to LiFePO4

A flooded or AGM marine battery loses voltage steadily as it drains, and pulling it below about half charge shortens its life. In practice that means you carry twice the battery you actually use. A LiFePO4 marine battery lets you draw most of its rated capacity on every trip and still delivers over 4,000 charge cycles, which is why it behaves like a true deep discharge marine battery rather than a consumable you replace every few seasons.

• Less weight in the hull. The 12V 105Ah weighs about 24 lbs, and the larger models come in at roughly one-third the weight of a lead-acid bank with the same energy. That matters on a kayak, a jon boat or any skiff where every pound affects draft.
• Consistent thrust. Flat voltage means the speed you set at 9 a.m. is still the speed you get at 3 p.m.
• No watering or acid. The cells are sealed, there is nothing to top up, and the batteries can sit through the off-season with very low self-discharge.

Which 12V Trolling Motor Battery Fits Your Boat?

All three models share the same 12.8V platform, Grade A LiFePO4 cells, IP65 housing and Bluetooth app. The difference is how many hours you want on the water and how much room you have in the battery compartment.

Vipboss 12V 105Ah Bluetooth LiFePO4 Lithium Battery is the lightweight trolling motor battery of the range. It stores 1,344Wh in a Group 31 case (12.95 × 6.77 × 8.42 in), so it drops into most existing battery boxes. Its 100A BMS comfortably handles 12V transom and bow-mount motors, making it a good kayak battery for trolling motor setups, a single-battery jon boat, or a dedicated fish finder battery on a larger boat.

Vipboss 12V 210Ah Bluetooth LiFePO4 Lithium Battery doubles the energy to 2,688Wh and steps up to a 200A BMS. It suits anglers who fish full days in wind and current, use spot-lock for long stretches, or want one battery to run both the motor and the electronics.

Vipboss 12V 320Ah Bluetooth LiFePO4 Lithium Battery carries 4,096Wh in one case. It is built for heavy multi-species rigs, guide boats and tournament anglers who need dawn-to-dusk runtime. The 210Ah and 320Ah share a 20.55 × 9.45 × 8.58 in footprint, so measure your compartment before you order.

Matching Battery Voltage to Your Trolling Motor

Trolling motors are made in 12V, 24V and 36V versions, and the battery bank has to match the motor, not the boat. Each Vipboss battery supports series connection up to four units, so the same three models cover every common motor voltage.

When you build a 24V or 36V bank, use identical models bought at the same time so every battery starts at the same capacity and ages at the same rate. Charge the bank with a lithium-compatible charger: a multi-bank onboard marine charger that charges each 12V battery separately is the most common setup. If you are deciding between one high-voltage pack and three 12V batteries, our guide to 36V trolling motor setups compares both approaches.

How Long Will It Run Your Trolling Motor?

Runtime depends on how hard you push the motor. Slow trolling on a calm morning draws a fraction of what the same motor pulls holding position against wind. The table converts each model into hours at typical average current draws. The same figures apply to a 24V or 36V series bank built from that model.

Estimates assume about 90% usable capacity and the motor as the only load. Actual hours vary with thrust setting, hull, wind, current and any electronics sharing the battery.

A lead-acid battery with the same amp-hour rating delivers noticeably less than these numbers, because draining it this far damages it. For a closer look at sizing, see what lithium battery capacity your boat needs.

Built for Spray, Vibration and Cold Mornings

Every model has an IP65 enclosure, which keeps out dust and splashing water. It is not rated for submersion, so mount the battery in a dry, ventilated compartment and secure it against hull slap. Our marine lithium installation guide covers fusing, cable sizing and tie-downs.

The built-in smart BMS protects against overcharge, over-discharge, overcurrent, short circuit and temperature extremes. Charging pauses below 32°F and resumes automatically at 41°F, while discharge works down to -4°F, so early-season and late-fall trips are covered. Through the Bluetooth app you can check state of charge and voltage from the console and know exactly how much trolling time is left before you head back to the ramp.

Charging and Off-Season Care

Charge with a LiFePO4 profile set to 14.2V to 14.6V. Recommended charge currents are about 21A for the 105Ah, 42A for the 210Ah and 64A for the 320Ah, so the battery is ready again overnight. At the end of the season, store the battery partly charged in a cool, dry place. Thanks to its low self-discharge, it will still have power in spring. The marine winterization guide explains whether to leave it on the boat or bring it home. Need help choosing between models? Compare them side by side in our full 12V LiFePO4 battery range.
