FAQs
What's the different lithium battery and LiFePO4 battery ?
"Lithium battery" broadly refers to rechargeable batteries using lithium ions, including Li-ion, LiPo, and LiFePO₄ types.
LiFePO₄ batteries are a specific kind with lithium iron phosphate cathodes, known for:
- High safety and thermal stability
- Long cycle life
- Steady power output
- Strong chemical stability
- Slightly lower energy density than other lithium types
How do I store Power Queen LiFePO4 lithium batteries?
When storing lithium batteries, it is recommended to store LiFePO4 lithium batteries at a 50% state of charge (SOC).
For prolonged storage, it is advisable to cycle the batteries at least once every six months.
Recommended storage environment:
- Temperature: 10℃~35℃ (50℉~95℉)
- Humidity: 45%RH~75%RH
Can a lead-acid charger charge Power Queen LiFePO4 batteries?
We do not recommend using a lead-acid charger charge LiFePO4 battery, it will affect the long-term performance of the battery.
For Power Queen LiFePO4 batteries , we recommend using battery charger that support lithium iron phosphate (LiFePO4) battery charging.
Would a single Power Queen 24V LiFePO4 deep cycle battery be better than two 12V batteries in series?
In a battery system, fewer batteries generally make the system more stable.
A single 24-volt LiFePO4 deep cycle battery is more stable than two 12-volt LiFePO4 deep cycle batteries connected in series to form a 24-volt battery pack because of the voltage difference between the battery connections. This is why we prefer to use a single 24V battery.
Is it better to have a single Power Queen 200Ah lithium battery or two 100Ah lithium batteries?
Between a single 200Ah deep cycle lithium battery and two 100Ah deep cycle lithium batteries, we recommend using a 200Ah battery. It is because a single battery is more stable than two batteries connected in parallel.
If your space is not limited, both models of batteries are ok. However, if space is limited, we recommend using a single 200Ah battery.
Why does Power Queen lithium battery declare a 10-year lifetime but only provide a 5-year warranty?
We’re sorry for the confusion caused by "10-year lifetime" and "5-year warranty." A 5-year warranty is not the same as a 10-year lifetime. We provide a 5-year warranty service for poor battery performance if they are used correctly according to the user manuals.
The battery life of lithium ion batteries depends on proper use and maintenance. Our batteries, made of automotive-grade cells with superior quality, can last about 10 years when cared for properly.
Where is my order shipped from?
We have multiple warehouses located in US. We will arrange the shipment from the nearest warehouse according to your shipping address and stock situation.
