FAQ
What are the advantages of upgrading to a lithium wheelchair mobility scooter battery?
Lithium batteries are lighter, lowering the overall weight of electric vehicles while enhancing energy efficiency and acceleration performance. Supports 4P4S, which meets the requirements for long-range mileage.
The BMS features a self-recovery protection function, which means that once protection is triggered, there is no need to disconnect and reconnect the load, making it easier to use.
This wheelchair batteries contain a low-temperature protection mechanism that stops charging at 0°C, resumes charging at 5°C, and prevents discharge at -20°C.
With certifications and test reports: UL-2271, FCC, CE, ROHS, and UN38.3. This lithium battery meets worldwide safety, environmental, and performance standards, providing customers with dependable and safe power for a variety of applications.
Can I connect the battery in series or parallel?
Yes. Power Queen 12V 45Ah lithium battery supports up to four in parallel and four in series (Max. 4P4S) to create a 51.2V 180Ah battery system with 9216Wh of energy and a maximum load power of 9216W. It has multiple applications, including wheelchairs, mobility scooters, campers, backup power, trolling motors (＜30 lbs), and off-grid systems.
To connect batteries in series or parallel, they must be identical with the same capacity (Ah) and BMS (A), from the same brand (since different manufacturers have unique BMS), and purchased within a month.
Are Power Queen LiFePO4 Lithium batteries safe?
Yes, LiFePO4 (Lithium Iron Phosphate) is one of the safest and most stable forms of lithium batteries available today. Power Queen lithium cells are UL certified, ensuring the greatest levels of safety and sustainability. Each Power Queen LiFePO4 battery contains an inbuilt Battery Management System (BMS) that provides full protection against a variety of dangers. These include under-voltage during discharge, over-voltage while charging, over-current during discharge, over-temperature during both charging and discharging, and short-circuit events, which ensure the battery cells are not harmed. Furthermore, Power Queen LiFePO4 batteries have been carefully tested and proven to be free of fire and electric shock concerns, even in harsh conditions.
Can I use Power Queen LiFePO4 Lithium batteries as starting batteries?
No. Power Queen LiFePO4 lithium batteries are not intended to be used as starting batteries but energy storage, please do not use them to start any devices.
For further details, please consult the "Deep Cycle VS Starting Battery" article.
Can I charge the Power Queen LiFePO4 lithium batteries in cold weather (below freezing)?
LiFePO4 batteries may be securely charged at temperatures ranging from 32℉ to 122 ℉ (0℃ to 50℃). The Power Queen 12V 45Ah Group U1 Lithium Battery includes low-temperature charging protection, which prevents charging if the battery cell temperature drops below 32°F. This function protects the battery cells from harm when charged under cold conditions.
Why is 12V lithium batteries so popular?
12V lithium batteries are popular because they are compatible with many common devices and systems, including cars, boats, and solar setups. Their popularity comes from the fact that 12V has been the standard for a long time, especially in vehicles. Lithium batteries offer a better alternative to older battery types because they are lighter, last longer, and perform more efficiently. This makes 12V lithium batteries a preferred choice for modern applications that need reliable and consistent power.
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.
