Power Queen 12.8V 100Ah Trolling Motor LiFePO4 Battery - Low Temp

In this review of the Power Queen 12.8V 100Ah trolling motor LiFePO4 battery, the verdict is straightforward: this pack is aimed at anglers and small-RV users who need a lightweight, long-life deep cycle battery with reliable cold-weather charging protection. The single biggest reason to buy is the upgraded 100A BMS with a 1-second 500A withstand and a built-in low temperature cut-off that prevents charging below 32F, which protects cells during cold-weather charging and makes this battery especially practical for fishing in cooler conditions.

Key Features

• Upgraded 100A BMS: The built-in high quality BMS endures higher current loads and can tolerate a 500A surge for 1 second, useful for trolling motor start surges.
• Low temperature cut-off: The BMS cuts charging when cell temperature is below 32F and automatically resumes when cells warm, protecting cell life in cold weather.
• Grade A battery cells: Uses LiFePO4 cells rated for a long service life, with up to 15000 cycles at reduced depth of discharge and a projected 10-year lifespan.
• Lightweight and expandable: At roughly 22 lb and 1280Wh, the battery is much lighter than lead-acid equivalents and can be configured in 4S4P banks up to 51.2V 400Ah for larger systems.
• Automatic overload protection: The battery automatically recognizes overloads, protects itself, and recovers without manual resets, reducing downtime on the water.

Who It's For

The Power Queen 12.8V 100Ah is best for anglers running 12V-36V trolling motors (roughly 30-120 lb thrust range) who want a reliable, lighter alternative to lead-acid batteries and protection against cold-weather charging damage. It also suits small solar setups, RV auxiliary power, and users who value long cycle life and built-in BMS safety features.

Those who should look elsewhere include users needing very high continuous discharge beyond the BMS rating for prolonged periods, and buyers who require an integrated inverter or a different nominal voltage out of the box. This battery is a cell-level power source rather than a turnkey system with additional power electronics.

Pros & Cons

Pros

• Long-lasting Grade A LiFePO4 cells provide thousands of cycles and an extended service life compared with lead-acid alternatives.
• Upgraded 100A BMS tolerates short 500A surges and offers automatic overload protection and recovery, improving reliability for trolling motors.
• Low temperature cut-off prevents charging below 32F, protecting cells from cold-weather damage.
• Lightweight at about 22 lb and expandable into larger 51.2V banks for solar or RV use.

Cons

• Not intended as a fully integrated power system-requires compatible chargers, wiring, and possibly a separate inverter for AC loads.
• While the BMS handles short high-current surges, sustained very high continuous discharge beyond the BMS design should be avoided.

Specifications

Our Verdict

The Power Queen 12.8V 100Ah LiFePO4 battery is a strong value for anglers and small-RV users who want a lightweight, long-life deep cycle battery with robust BMS protections and cold-weather charging safety. It replaces heavier lead-acid options and provides expandable capacity for larger systems, though buyers should pair it with compatible chargers and avoid sustained discharge beyond the BMS continuous limits.

Frequently Asked Questions

Can this battery run a 12V trolling motor?
Yes, it is designed for 12V-36V trolling motors and is suitable for motors in the roughly 30-120 lb thrust range when used with appropriate wiring and controllers.

Will it charge in cold weather?
The BMS includes a low temperature sensor that prevents charging below 32F and automatically resumes charging once cell temperature rises above 32F to protect the cells.

How long will it last compared with lead-acid?
Using Grade A LiFePO4 cells, the pack is rated for up to 10 years and thousands of cycles (examples include 4000+ cycles at 100% DOD and up to 15000 cycles at lower DOD), substantially longer than typical lead-acid batteries.
