【🌸 Spring Deal】WattCycle 12V 314Ah Mini Deep Cycle Lithium Battery (Regular Version without Bluetooth)

Absolutely. LiFePO4 is the most stable lithium chemistry on the market. WattCycle cells are UL-certified and housed in an IP65-rated case. Our internal BMS guards against:

• Over Charge & Over Discharge
• Under Voltage & Over Voltage
• Over Current & Short Circuits
• High Temperature
• Low-temperature Cut-off

1. Cell Overcharge Protection and Recovery
When the voltage of any cell is higher than the set value of the cell overcharge voltage, and the time of duration reaches the cell overcharge delay, the system enters the overcharge protection state, the charging MOS will turn off, and the battery cannot be charged.
After the cell overcharge protection, when the voltage of all cells drops below the cell overcharge recovery value, the overcharge protection state is released. It can also be released by discharge.

2. Overall Overcharge Protection and Recovery
When the overall voltage is higher than the overall over-voltage set value, and the time of duration reaches the overall overcharge delay, the system enters the overcharge protection state, turns off the charging MOS, and cannot charge the battery.
When the overall voltage drops below the recovery value of the overall over-voltage protection, the overcharge protection state is released, and it can also be released by discharge.

No. Unlike lead-acid batteries, LiFePO4 deep cycle batteries do not require regular maintenance or water refilling. Simply store and operate within the recommended voltage and temperature ranges.

You can charge it with a LiFePO4 battery charger, solar panels + MPPT solar charge controller, or generator/alternator (with the correct voltage regulation). For optimal performance, use a charger specifically designed for LiFePO4 deep cycle batteries with the correct charging profile.

We recommend using a WattCycle LiFePO4 battery charger, which is specifically designed to meet the unique charging needs of LiFePO4 batteries. Alternatively, you can also charge the battery using photovoltaic solar panels through MPPT or use an inverter with a built-in AC to DC charging function.

Yes—our 12V 314Ah LiFePO4 Battery is designed for seamless solar charging. Simply pair it with an MPPT charge controller and a 1.200W PV array to top up in one sunny day (≈4.5 hrs of peak sun).

Optimal Setup: A 1.200W solar panel bank feeding an MPPT regulator ensures efficient charging of your 12V 314Ah solar battery.

Charge Profile: MPPT controllers adjust voltage/current to maintain the ideal 14,2V – 14,6V range, protecting cell health and maximizing cycle life.

Scalable: Whether you’re building out 12V 314Ah batteries for solar panels in parallel or keeping it simple with one pack, the WattCycle system adapts—no special wiring or firmware tweaks required.

1. Recommended Storage Conditions

• To achieve optimal storage results, 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 avoid moisture buildup.

2. Recommended Charge Level During Storage
LiFePO4 batteries should be stored at a partial state of charge (SOC) between 50% and 80%.

Why Avoid Full Charge/Discharge?

• Storing the battery fully charged or fully discharged can stress the cells and lead to gradual capacity loss over time.
• A partial charge helps preserve battery health during storage.

Additional Tips:

• Check Periodically: If storing for extended periods (>3 months), check the SOC every 3–6 months and recharge to 50–80% if needed.
• Avoid Extreme Temperatures: Never store in freezing (<0°C) or excessively hot (>60°C) environments.
