What's the different lithium 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?

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: 10℃~35℃ (50℉~95℉),45%RH~75%RH.

Can a lead-acid charger charge Power Queen LiFePO4 batteries?

We do not recommend using a lead-acid charger charge your LiFePO4 batteries, 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 battery be better than two 12V batteries in series?

In a battery system, the less the quantity of batteries, the more stable the system will be.
A single 24-volt battery is more stable than two 12-volt 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 battery or two 100Ah batteries?

Between a single 200Ah battery and two 100Ah 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 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 the poor performance of the batteries if they are used correctly according to the user manuals.
The batteries can be used for about 10 years if properly used and maintained because they are made of automotive-grade battery cells with superior quality.
