How long will a 24V 100Ah lithium battery run a trolling motor?

Runtime depends on the trolling motor’s average current draw, boat weight, speed, wind and water conditions. As a simple theoretical guide: 20A average draw: approximately 5 hours 40A average draw: approximately 2.5 hours 60A average draw: approximately 1.7 hours Trolling motors usually consume much less power at lower speeds, so real-world runtime can vary considerably.

WattCycle 24V 100Ah LiFePO₄ Deep Cycle Battery for Trolling Motors, Marine & Off-Grid Power

Q: What charger should I use for this 24V LiFePO₄ battery?

Use a dedicated 29.2V LiFePO₄ battery charger or a properly configured 24V-compatible MPPT or DC-DC charging system. With a 29.2V 15A charger, a full charge from empty generally takes approximately 7–8 hours. Charging time varies according to remaining capacity, temperature and charger output.

Q: Can WattCycle 24V 100Ah batteries be connected in series or parallel?

Yes. The battery supports expansion up to 4P2S , providing a maximum system capacity of 20.48kWh. For a 24V system, connect matching batteries in parallel. A series connection increases the system voltage and should only be used with compatible 48V equipment. Always use batteries of the same model, capacity, age and state of charge, together with correctly rated cables, fuses and system protection.

Q: How long does the battery last, and what protection and warranty are included?

The Grade A+ LiFePO₄ cells are rated for 6000+ cycles at 80% DOD and can provide up to 10 years of service under suitable operating conditions. The built-in 100A BMS protects against overcharge, over-discharge, over-current and short circuits. It also features IP65 protection and low-temperature charging cut-off. The battery includes a 5-year warranty , with extended coverage available after product registration under the applicable warranty terms.

24V 100Ah LiFePO₄ Battery FAQs

This 2.56kWh deep-cycle lithium battery is designed for 24V trolling motors, marine house-power systems and small off-grid solar setups. It can support fridges, fish finders, navigation equipment, lighting, water pumps and other compatible 24V loads. It is not designed for engine starting.

Yes. It is suitable for many 24V trolling motors rated between 30 and 70 lb of thrust, provided the motor’s maximum continuous current does not exceed the battery’s 100A discharge limit. Always check the motor manual, recommended fuse, cable size and voltage before purchasing.

Yes. One WattCycle 25.6V 100Ah battery provides 2.56kWh—the same nominal energy as two 12.8V 100Ah batteries connected in series. Using one 24V battery reduces cables and connection points while simplifying installation and maintenance.

One battery is the most common choice for a standard 24V trolling motor or light marine loads. Choose two batteries in parallel for longer fishing trips, heavier boats or overnight marine use. Small cabins, farm sheds and remote solar systems may require two to four batteries, depending on daily consumption and available solar charging.

1 battery: 2.56kWh
2 batteries in parallel: 5.12kWh
3 batteries in parallel: 7.68kWh
4 batteries in parallel: 10.24kWh

Runtime depends on the trolling motor’s average current draw, boat weight, speed, wind and water conditions. As a simple theoretical guide:
