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

How to store LiFePO4 batteries?

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.

Frequently Asked Questions

Yes. Our 200 A BMS protects against charging or discharging in unsafe temperatures.

Charge cutoff: 0 °C – 45 °C
Discharge cutoff: –20 °C – 60 °C

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.

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

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.

Zero maintenance—no watering or equalizing. Just install, register your 7-year warranty, and enjoy consistent, long-lasting power for years to come.
