In this review, we'll explore its features, benefits, usage guidelines, and why it has become a popular choice for off-grid energy storage.

Product Overview

The Qidianfy 24V LiFePO4 battery is available in 100Ah and 200Ah capacities, making it suitable for both medium and large power requirements. Unlike traditional lead-acid batteries, LiFePO4 batteries provide higher energy efficiency, longer lifespan, lighter weight, and faster charging.

Whether you're powering solar panels, home backup systems, boats, electric equipment, or recreational vehicles, this battery delivers consistent and reliable performance.

Key Features

Advanced LiFePO4 Battery Technology

The biggest advantage of this battery is its Lithium Iron Phosphate chemistry.

Compared to AGM or lead-acid batteries, LiFePO4 offers:

Longer lifespan Higher safety Better thermal stability Faster charging Lower maintenance Lightweight construction

This technology also provides stable voltage during discharge, ensuring connected devices perform efficiently until the battery is nearly empty.

Large Energy Capacity

The battery delivers approximately:

24V 100Ah = 2560Wh 24V 200Ah = 5120Wh (depending on the selected model)

This makes it ideal for powering:

Solar energy systems Portable refrigerators LED lighting Home appliances Camping equipment RV electronics Marine accessories Emergency backup systems

Large energy storage means fewer charging cycles and longer operating time.

Built-in 100A Smart BMS

One of the most valuable features is the integrated 100A Battery Management System (BMS).

The BMS protects the battery from:

Overcharging Over-discharging Short circuits Overcurrent High temperature Low temperature Cell imbalance

This intelligent protection system significantly improves both battery safety and lifespan.

Excellent Cycle Life

Unlike conventional batteries that often last only a few hundred cycles, LiFePO4 batteries typically provide thousands of charge and discharge cycles.

With proper maintenance, users can enjoy years of reliable service before experiencing noticeable capacity reduction.

This makes the battery an excellent long-term investment.

Charge with Compatible Equipment

Always use a charger designed for 24V LiFePO4 batteries.

Avoid chargers intended for lead-acid batteries unless they specifically support LiFePO4 charging profiles.

Avoid Complete Discharge

Although LiFePO4 batteries tolerate deep discharge better than lead-acid batteries, avoiding complete depletion helps extend service life.

Recharge when the battery reaches a low state of charge.

Store Properly

If storing the battery for several months:

Keep it partially charged (around 40–60%) Store in a cool, dry environment Avoid excessive humidity Disconnect unused loads Monitor Temperature

While LiFePO4 batteries perform well across a wide temperature range, avoid charging in freezing conditions unless the battery includes low-temperature charging protection.

Keep Connections Tight

Inspect terminals periodically.

Loose connections can create unnecessary resistance and reduce efficiency.

Do Not Exceed Current Ratings

Avoid connecting loads that exceed the battery's rated discharge current.

Respect the limits of the built-in 100A BMS.

Advantages

Some of the biggest strengths include:

High energy density Excellent safety Long cycle life Maintenance-free operation Lightweight construction Fast charging capability Reliable BMS protection Excellent compatibility with solar systems Stable voltage output Eco-friendly battery chemistry
