FAQ
Are Power Queen LiFePO4 batteries safe?
Yes, LiFePO4 is an inherently safe chemistry and is considered the most stable lithium battery type on the market. Power Queen lithium cells are UL certified, meeting the highest standards for safety and sustainability. Each Power Queen LiFePO4 battery comes equipped with an internal Battery Management System (BMS) that offers protection against under-voltage during discharge, over-voltage during charge, over-current during discharge, over-temperature during both charge and discharge, and short circuits, safeguarding the battery cells. Additionally, Power Queen LiFePO4 lithium batteries have been rigorously tested to ensure they are free from the risk of fire and electric shock, even in harsh environments.
Can I use Power Queen LiFePO4 lithium batteries as starting batteries?
No, Power Queen LiFePO4 lithium batteries are specifically designed for energy storage and are not suitable for use as starting batteries. Avoid using them to start any devices.
For more information, explore the differences between Deep Cycle and Starting Batteries.
Can this battery be used in series to build a 48-volt system?
Yes. Power Queen 12V deep cycle lithium batteries can be connected 4 in series to create a 48V battery system.
Note: DO NOT connect batteries with different chemistries in series or parallel:
1. Batteries must be similar in terms of capacity (Ah) and BMS (A).
2. Batteries from the same brand are preferred, as different brands have unique BMS.
3. Batteries should be purchased within a month.
How many Power Queen 12V 300Ah lithium Batteries can I connect at most?
The 12V series batteries offer flexible connection options, including series, parallel, and series-parallel configurations. You can connect up to four 12V 300Ah batteries in series, four in parallel, or up to sixteen in a series-parallel setup, achieving a total capacity of 40.96 kW and 61.44 kWh of energy.
Ensure that batteries of the same model and similar capacity are used for these configurations.
How do I store Power Queen LiFePO4 lithium batteries?
It is recommended to store Power Queen LiFePO4 batteries at 50% state of charge (SOC). If the batteries are stored for long periods, cycle the batteries at least every 6 months. Recommended storage environment: 10℃～35℃ (50℉～95℉), 45%RH～75％RH.
Can I charge Power Queen LiFePO4 lithium batteries with solar panels?
Yes, you can charge Power Queen LiFePO4 lithium batteries with solar panels. Here are 3 recommended ways to charge LiFePO4 lithium batteries.
1. Using Solar Panels
The Power Queen 12V 300Ah lithium battery can be fully charged by in one day (with effective sunshine 4.5hrs/day) by 1200W solar panels. It may take more than one day to fully charge the battery by ≥1200W solar panels since the duration and intensity of light would be a great factor for their charging efficiency.
2. Generator/Alternator
If the alternator or generator supports DC output, a DC-to-DC charger is needed to connect the battery to the generator; if your alternator or generator supports AC output, please add a suitable battery charger to connect the battery and the generator according to our recommendations.
The Recommended Charging Voltage: 14.2V - 14.6V. The Recommended Charging Current: ① 60A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 150A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.
3. LiFePO4 Smart Chargers
To charge 12V battery, it is recommended to use 14.6V battery charger.
The Recommended Charging Voltage: 14.2V - 14.6V.
The Recommended Charging Current: ① 60A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 150A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.
Related reading: Can I Charge a Lifepo4 Battery With a Lead Acid Charger?
Can Power Queen LiFePO₄ batteries be used to charge a portable power station?
No, we do not recommend using Power Queen batteries to charge portable power stations such as EcoFlow or Bluetti. This may lead to over-discharge, triggering the battery’s protection mode and causing it to remain in a low-voltage state that cannot be reactivated.
