Watch the full walkthrough in the video above — a real-world 24V lithium trolling motor installation covering wiring, charging, and on-water performance.
Why Trolling Motor Batteries Matter for Anglers
Your trolling motor is your most important piece of fishing gear. It positions you on fish, holds you against wind and current, and keeps you fishing all day. Losing battery power mid-session — or having a trolling motor running sluggishly on a depleted lead-acid bank — costs you fish.
LiFePO4 lithium batteries solve every common trolling motor battery problem:
- More runtime — up to double the effective capacity at the same weight
- Consistent power — voltage stays high until the battery is genuinely empty
- Less weight — critical for boat trim and fuel economy
- Longer life — 3,000+ cycles versus ~500 for AGM
Wiring a 24V Lithium System
Series Configuration (2× 12V)
Connect two Revolution Power 12V batteries in series:
- Mount both batteries securely — vibration is the enemy of any connection
- Use appropriately rated cable — for a 80lb thrust motor drawing 50A peak, use 6AWG minimum, 4AWG preferred
- Fuse at each battery's positive terminal — not just at the motor
- Connect: Battery 1 (+) → Battery 2 (−) [series link], Battery 2 (+) → Motor (+), Battery 1 (−) → Motor (−)
Standalone 24V Battery
A single Revolution Power 24V battery is even simpler: two terminals, one fuse, connect directly to the motor. The internal BMS handles all protection.
The Performance Advantage
AGM batteries drop voltage as they discharge. At 50% state of charge, a 24V AGM bank might be providing 23.0V. At 80% discharged, it could be below 22V.
Most 24V trolling motors are rated for 24V ±10%. At 22V the motor loses significant thrust — you're working the motor harder to maintain position against current, using more current, draining the battery faster. It's a downward spiral.
Revolution Power LiFePO4 batteries maintain 26–27V until below 10% remaining capacity. Your trolling motor runs at full designed performance all day.
Tournament Considerations
In tournament fishing, consistent performance and reliability are everything. Lithium batteries give you:
- Full thrust in the final minutes — as important as the first cast
- Charging overnight — LiFePO4 charges faster, so a full recharge is achievable from a standard charger in 4–5 hours
- Weight savings — replacing 50kg of AGM with 18kg of lithium affects your boat's trim and run angle
- No maintenance — no checking electrolyte, no equalisation charges, no terminal corrosion
Charging After a Tournament Day
Use a dedicated 24V LiFePO4 charger. The Victron Blue Smart IP22 24V/16A is a popular choice — it connects to the VictronConnect app so you can monitor charging from the motel room overnight.
Never charge a 24V lithium series bank with two 12V chargers connected to each battery independently. Always charge as a 24V system with a 24V charger.
