The main difference between the Power Queen Group 24 and Group 31 batteries lies in their physical dimensions, with Group 24 batteries typically being smaller than Group 31 batteries.

For more details, you can explore the comparison between Deep Cycle Group 24 and Group 31 batteries.

The Group 24 battery, a standard model, measures 10.5″L x 6.1875″W x 8.875″H and is commonly used in vehicles, backup power systems, and medical equipment. These batteries are often employed as deep cycle batteries rather than for engine starting purposes.

When you receive your battery, please note that it may arrive with a low State of Charge (SOC) due to transportation and storage. To ensure optimal performance, we recommend promptly charging the battery to avoid the risk of over-discharge.

If you intend to store the battery for an extended period without use, it's advisable to charge it to 50% SOC and conduct maintenance every three months. These practices will help preserve the battery's functionality and performance over time.

The 12V lithium battery from Power Queen allows for a maximum of 4 batteries to be connected in series and 4 in parallel, enabling you to create a battery system with up to 16 units. This configuration offers a maximum capacity of 20.48 kWh and a peak power output of 20.48 kW.

Note: When connecting batteries in series or parallel, ensure they meet the following conditions:

a. They must be identical, with the same battery capacity (Ah) and BMS (A).

b. They should be from the same brand, as lithium batteries from different brands have unique BMS systems.

c. They should be purchased within a short time frame (within one month).

No, Power Queen LiFePO4 lithium batteries are designed for energy storage, not for starting devices. Therefore, please do not use them to start any equipment.
