Frequently asked questions

Yes, we recommend purchasing a charger specifically designed for lithium iron phosphate batteries. Please ensure the charging current does not exceed the battery's allowable charging current. Alternatively, you can use photovoltaic solar panels with MPPT (Maximum Power Point Tracking) technology to charge the battery, or use an inverter with built-in AC-to-DC charging functionality.

Of course. Lithium iron phosphate batteries are currently the most stable lithium battery chemistry system on the market. Our built-in Battery Management System (BMS) prevents:

Overcharging and over-discharging

Undervoltage and overvoltage

Overcurrent and short circuit

High-temperature protection

Low-temperature protection

Yes—our 12V 314Ah lithium iron phosphate battery is designed for seamless solar charging. Simply pair it with an MPPT charge controller and a 1200W photovoltaic array to fully charge it in a sunny day (approximately 4.5 hours of peak sunshine).

Optimal Recommended Configuration: A 1200W solar panel array powers the MPPT controller, ensuring efficient charging.

Battery Charging Curve: The MPPT controller regulates voltage/current to maintain an ideal 14.2V – 14.6V range, protecting battery health and maximizing cycle life.

1. Recommended Storage Conditions

For optimal long-term storage, LiFePO4 batteries should be kept in a cool, dry place.

Ideal Storage Temperature: 15°C – 25°C.
Humidity: Keep humidity as low as possible to prevent moisture buildup.

2. Recommended State of Charge (SOC) for Storage

LiFePO4 batteries should be stored at a partial state of charge between 50% and 80% SOC.

Why Avoid Full Charge/Discharge?
Storing a battery at either a fully charged (100%) or fully discharged (0%) state puts stress on the cells and can lead to a gradual loss of capacity over time. A partial charge helps maintain battery health during storage.

Additional Tips:

Periodic Check: For long-term storage (>3 months), check the SOC every 3-6 months and recharge to 50-80% if necessary.
Avoid Extreme Temperatures: Never store batteries in freezing (<0°C) or excessively hot (>60°C) environments.

Generally speaking, lithium iron phosphate batteries can be used stably for their designed lifespan under correct operating conditions without maintenance.

EEL 12V: The Revolutionary LiFePO4 Battery. Massive Power, Compact Size.

Built with a 200A JK BMS (Battery Management System), it ensures a continuous 200A (1C) discharge/charge current. Utilizing EV-grade A+ cells, it stores 4.01kWh of energy, providing ample power for your RV trips, outdoor camping adventures, and more.

EEL 12V 314Ah 4kwh LiFePO4 battery for RV,EV,Golf cart,mobile power supply.

Why Choose This EEL 12V 314Ah Bluetooth Lithium Battery?

It utilizes high-performance, EV-grade A+ cells and an advanced 200A JK BMS, delivering 4.01kWh of energy and a maximum output power of 2560W, with an exceptional cycle life of up to 8,000 cycles. Its robust external metal casing protects against bumps and impacts, while the internal metal framework ensures the battery's safety even on rough terrain. The Bluetooth function allows you to monitor the battery's status anytime, anywhere, even when it's installed in "hidden" locations (e.g., under an RV seat).

Featuring high and low-temperature cutoff protection, it ensures your powered devices operate reliably even in extreme cold or heat. During use, if the temperature drops between -25°C and -15°C, the BMS activates a protection mechanism and initiates self-heating. The battery resumes discharging once the temperature rises to between 5°C and 15°C.

The Ultimate Upgrade from AGM Battery

EEL BATTERY's flagship 12V 314Ah Mini Bluetooth Lithium Battery redefines portable power with its space-saving dimensions (L 382 × W 221 × H 252 mm) and an ultralight body weighing just 35 kg. It delivers 2560 watts of output power and 4019 watt-hours of capacity, far outperforming traditional setups—replacing three bulky lead-acid batteries (weighing up to 87 kg) that provide only 1800 watts/1800 watt-hours. This represents a smarter and more efficient energy solution for the modern user.

Enables easy Bluetooth connectivity for smart battery control.

Take full control of your power system in just three steps: install the JK BMS app, detect your Bluetooth batteries, and pair them through the app interface. The app is easy to download—scan the provided QR code or search for "JK BMS" directly on Google Play or the Apple App Store.
