LiTime 24V 50Ah LiFePO4 Deep Cycle Battery - Marine Group 24

In this review the LiTime 24V 50Ah LiFePO4 battery is examined as a compact, marine-ready power source for trolling motors and small onboard systems. The bottom line: it is aimed at anglers, small boat owners, and RV users who want a lighter, longer-lasting alternative to lead-acid batteries. The single biggest reason to buy is the combination of a built-in 50A BMS with heavy cycle life, which delivers dependable, safe performance over years while saving space compared with two 12V batteries.

Key Features

• Marine-grade design: TVS surge protection and shock resistance help the battery withstand wet, rough conditions common on boats and trolling motor installations.
• High cycle life: Rated for 4,000+ cycles at 100% DOD (6,000 at 80% DOD and 15,000 at 60% DOD), this battery is built for long-term daily use without rapid capacity loss.
• Built-in protection: The integrated 50A BMS provides over 20 protections to reduce the risk of faults during charging, discharging, and short events.
• Bluetooth 5.0 monitoring: Live readings of SOC and voltage via Bluetooth let users track state of charge and avoid unexpected shutdowns during outings.
• Low-temperature safety: Automatic cutoff stops discharging below -4F (-20C) and prevents charging below 32F (0C), which is useful for cold-weather fishing or winter storage.
• Compact Group24 size: At roughly 10.24in x 6.61in x 8.3in and 21 lbs, it saves space and weight versus two 12V batteries while providing a 24V output for 70-100 lb thrust motors.

Who It's For

The LiTime 24V 50Ah is best for anglers who run 24V trolling motors in the 70-100 thrust range and need a durable, waterproof-tolerant battery that is lighter than equivalent lead-acid setups. It also suits small boat owners, yacht tenders, and RV users who want a compact 24V pack to power accessories or off-grid systems.

Those who need very high continuous discharge above the built-in 50A BMS limit or operate exclusively in freezing charging conditions should consider other options. If raw, inexpensive upfront capacity is the priority over lifecycle cost and weight, traditional flooded or AGM batteries may still be preferable for some buyers.

Pros & Cons

Pros

• Long lifecycle with thousands of cycles, offering lower total cost of ownership than lead-acid alternatives.
• Integrated 50A BMS and TVS surge protection deliver robust safety for marine and RV use.
• Bluetooth 5.0 monitoring provides convenient real-time SOC and voltage data to prevent surprises.
• Compact Group24 format saves weight and space while providing a true 24V solution for trolling motors.

Cons

• 50A BMS limits maximum continuous discharge compared with some high-current lithium packs, which may not suit very demanding motor setups.
• Charging is disabled below 32F (0C), which restricts use in freezing conditions unless warmed or managed carefully.

Our Verdict

The LiTime 24V 50Ah LiFePO4 battery is a strong pick for boaters and RV owners who need a compact, durable 24V pack with long life and built-in safety. Its marine-focused protections, Bluetooth monitoring, and high cycle ratings make it good value over time for routine use with 70-100 thrust trolling motors or small onboard systems, provided the 50A discharge limit meets the intended load.

Frequently Asked Questions

Can this battery run a 24V trolling motor?
Yes, it is designed for 24V trolling motors in the 70-100 thrust range, though users should confirm their motor's current draw stays within the 50A BMS limit.

Will it work in cold weather?
It has low-temperature protection that prevents discharge below -4F (-20C) and charging below 32F (0C), so it will protect itself in cold conditions but may require warming for charging or heavy use.

How does Bluetooth monitoring help?
Bluetooth 5.0 provides live SOC and voltage data to the user, helping prevent unexpected shutdowns by making charge status and overall battery health easy to monitor.
