24V 100Ah LiFePO4 Battery 2-Pack - High Cycle, 2560W Output

In this review the reviewer looks at the 2 pack 24V 100Ah LiFePO4 lithium batteries and finds them best suited for campers, RVs, small off-grid solar systems and marine trolling motors that need a reliable, lightweight power source. The single biggest reason to consider this pack is sustained, stable power delivery: at 24V and up to 2560W continuous output with a built-in 100A BMS, these batteries replace heavier lead-acid options while offering long life and simpler wiring for 24V systems.

Key Features

• 24V 100Ah capacity: Each battery delivers 2.56kWh of usable energy, equivalent to two 12V 100Ah batteries in a single 24V unit for fewer connections and cleaner installs.
• Built-in 100A BMS: The integrated battery management system protects against overcharge, over-discharge and short circuits for safer operation in mobile and stationary systems.
• High power output: Continuous power delivery up to 2560W supports demanding loads such as inverters for camper appliances or small air conditioners.
• Long cycle life: Rated for thousands of cycles and an estimated 10-year lifespan, the chemistry supports extended use for solar storage and repeated deep cycles.
• Lightweight design: At about 48.06 lbs per battery, the pack is substantially lighter than comparable lead-acid batteries, easing installation and transport.
• Scalable connections: Supports series and parallel connections up to 1S4P so systems can be expanded for larger capacity or higher voltage.

Who It's For

The 2 pack 24V 100Ah LiFePO4 set is ideal for RV owners, boaters and solar hobbyists who need a compact, long-lived battery bank that simplifies wiring by using 24V natively. It suits anyone replacing heavy lead-acid banks who values weight savings and longer service life for frequent cycling.

It is less suitable for users who need extremely high peak discharge beyond the 100A BMS limit without additional equipment, or those who require proprietary integrations not supported by a standard LiFePO4 BMS. Buyers should also plan to charge or cycle the batteries at least once every six months if stored to avoid damage from disuse.

Pros & Cons

Pros

• High energy density and 24V output reduce wiring complexity and provide steady power for 24V systems.
• Built-in 100A BMS offers essential protections for safe everyday use in mobile and off-grid setups.
• Lightweight and long-lived compared with lead-acid, making it practical for RV and marine use.

Cons

• Some customers report mixed impressions of usable capacity for certain camper setups, so run-time will vary by load and system efficiency.
• Voltage and current readings can deviate by 1% to 5% depending on measurement conditions, so expect small variances in real-world figures.

Our Verdict

For RV, marine and small off-grid solar users who need a lighter, longer-lasting alternative to lead-acid, this 24V 100Ah LiFePO4 2-pack is a strong value thanks to its built-in 100A BMS, 2560W output and expandable design. It provides safer, cleaner power and easier installs for 24V systems, though buyers should confirm run-time for their specific loads and follow storage charge recommendations.

Frequently Asked Questions

How long will these batteries last in regular use?
With regular cycling they are rated for thousands of cycles and an estimated 10-year lifespan; cycle life will depend on depth of discharge and use patterns.

Can these be connected for larger systems?
Yes, the batteries support series and parallel connections up to 1S4P to scale voltage or capacity for larger installations.

Are there special storage requirements?
Charge or discharge at least once every six months to prevent damage from disuse, and expect small measurement variances of 1% to 5% depending on conditions.
