Product Description

Step into the future of reliable energy storage with a power solution meticulously engineered for demanding operational environments. Housed in a rugged, high-impact plastic casing, this 24V 100Ah LiFePO4 Deep Cycle Battery feels exceptionally solid yet surprisingly lightweight when handled. The matte finish of the exterior resists abrasions and environmental wear, while the heavy-duty, precision-machined terminals ensure a flush, high-conductivity connection that minimizes electrical resistance. When integrated into a power array, it operates in absolute silence, replacing the constant hum, vibration, and off-gassing odors of traditional lead-acid units with clean, odorless, and highly efficient energy delivery.

Beneath the robust exterior lies a sophisticated internal architecture designed to maximize usable energy and protect your investment. Delivering a formidable 2.56kWh of power, this unit transforms how commercial fleets, off-grid solar arrays, and marine vessels manage their energy reserves. Every internal component is securely mounted and insulated to withstand persistent vibrations, ensuring that power delivery remains uninterrupted even in turbulent maritime conditions or rough off-road transit. By eliminating the need for routine fluid top-ups, terminal descaling, and equalization charges, this battery allows operators to redirect their focus from equipment maintenance to core operational productivity, securing the continuous, high-output power flow that modern applications demand.

1. Ultra-Long Cycle Life & Durability

Built with LiFePO4 cells, the battery provides ≥3000 cycles at 85% DOD, lasting over 8-10 years under normal use. This is 3-4 times longer than traditional lead-acid batteries, significantly reducing replacement costs. The stable chemistry ensures consistent performance and safety, with no risk of thermal runaway.

2. High Efficiency & Power Output

With 100% charge efficiency at 0.2C and 96-99% discharge efficiency at 1C, the battery minimizes energy waste, maximizing usable power. It supports a 100A continuous discharge current, powering high-demand loads like inverters, motors, and appliances with ease.

3. Comprehensive BMS Protection

The integrated 100A BMS protects against overcharge, over-discharge, over-current, and short circuits, ensuring safe and reliable operation. It balances cells during charging, preventing damage from voltage imbalances and extending battery life. The BMS also provides over-temperature protection, suitable for use in extreme conditions.

4. Wide Operating Temperature Range

Designed for diverse climates, the battery operates from 0~45℃ for charging and -20~60℃ for discharging. This makes it ideal for both cold winters and hot summers, maintaining performance in outdoor and off-grid environments. The storage temperature range of 0~40℃ ensures safe long-term storage.

5. Low Self-Discharge & Maintenance-Free

With a self-discharge rate of ≤3% per month, the battery retains its charge for long periods, reducing the need for frequent recharging. The sealed, maintenance-free design eliminates the need for water topping or corrosion checks, making it ideal for remote installations and off-grid use.

1. Solar Energy Storage for 24V Systems

The battery is ideal for storing energy from 24V solar panels, providing reliable power for nights and cloudy days. Its high efficiency and cycle life ensure long-term performance, while the wide temperature range suits diverse climates. It’s compatible with most 24V solar charge controllers and inverters.

2. RV & Camper Van Power Systems

Power 24V RV appliances, lighting, and electronics with confidence. The 100Ah capacity supports extended off-grid trips, and the BMS ensures safe operation. The low self-discharge rate reduces maintenance, making it perfect for seasonal use and long journeys.

3. Marine & Trolling Motor Applications

Boaters and anglers rely on the battery for 24V trolling motors, fish finders, and on-board electronics. The deep cycle design provides consistent power, and the plastic casing protects against splashes. The long cycle life reduces the need for frequent replacements.

4. Backup Power for Emergency & Off-Grid Use

The battery serves as a reliable backup power source for blackouts, powering essential appliances and communication devices. The 2.56kWh capacity and high discharge current support critical loads, ensuring safety and comfort during emergencies.

Install the battery in a well-ventilated, cool location. Connect the positive and negative terminals to your system, observing polarity. Use a LiFePO4-specific charger to charge the battery, setting the cut-off voltage to 29.2V. The integrated BMS will manage charging and discharging automatically. Avoid exposing the battery to extreme temperatures outside the specified range. Store in a cool, dry place when not in use.

Q1: How does the integrated BMS handle high-surge inductive loads, such as air conditioning units or heavy motors?

The built-in Battery Management System is specifically engineered to support a massive continuous discharge current of 100A. This robust handling capacity ensures that the battery can easily absorb the initial high-surge demands of inductive loads without triggering premature over-current protection, providing a smooth, stable, and uninterrupted power delivery to your critical appliances.

Q2: Can this 24V 100Ah battery be integrated into an existing solar array utilizing a standard MPPT charge controller?

Yes, it is highly compatible with most modern MPPT solar charge controllers and inverters. To ensure optimal charging efficiency and to maximize the battery's lifespan, simply configure your charge controller's profile to a LiFePO4 setting, specifically adjusting the charge cut-off voltage to the recommended 29.2V.

Q3: What are the long-term storage requirements if the battery is not deployed immediately?

Thanks to its exceptionally low self-discharge rate of ≤3% per month, the battery requires minimal maintenance during storage. We recommend storing the unit in a cool, dry environment between 0~40℃ at approximately a 50% state of charge. A brief top-up charge every 3 to 6 months is advisable to maintain peak cell health and readiness.

Q4: Is it possible to scale up the system voltage or capacity by wiring multiple units together?

Absolutely. The battery architecture supports highly flexible expansion. You can safely connect multiple identical units in parallel to increase your total amp-hour capacity, or in series to build higher voltage systems (such as 48V arrays). Always ensure all batteries are of the exact same model, fully charged, and perfectly voltage-balanced before linking them.

Q5: How does the LiFePO4 chemistry perform in freezing conditions compared to traditional lead-acid batteries?

Unlike lead-acid batteries that suffer severe capacity loss and risk physical cracking when frozen, our premium LiFePO4 cells are designed to safely and efficiently discharge in temperatures as low as -20℃. While charging below freezing requires careful management (which is automatically handled by the intelligent BMS), the discharge performance remains highly robust, making it the ideal choice for harsh winter deployments and remote off-grid cabins.
