Power Queen 29.2V 20A LiFePO4 Battery Charger – Fast and Safe Charging
The Power Queen 29.2V 20A LiFePO4 battery charger is designed for efficient and rapid charging of 24V 100Ah LiFePO4 batteries. This charger offers reliable performance without compromising safety, ensuring your battery is charged quickly and efficiently, making it ready for use in no time.
Comprehensive Safety Features for Reliable Charging
The Power Queen 29.2V 20A charger comes with four essential safety features: Output Over-voltage Protection to prevent battery damage, Over-temperature Protection to ensure safe operation, Reverse Polarity Protection to avoid incorrect connections, and Output Short-circuit Protection for quick response to electrical faults. These features guarantee safe and reliable charging every time.
LED Indicator for Easy Monitoring
The Power Queen charger’s LED indicator provides clear feedback on the charging status: Red means the battery is charging, Green indicates it’s fully charged, Flashing Red alerts you to a fault or protective mode, and Flashing Green shows the charger is on standby. This ensures you're always informed about the battery's condition.
Upgraded Connection for Easy and Safe Use
Equipped with a new Anderson connector and M8 battery terminal, the Power Queen charger offers a more convenient and user-friendly experience. These connection options ensure secure and efficient charging, optimizing battery protection while maximizing charging speed.
Efficient 3-Stage Charging with Battery Activation
The Power Queen charger features a 3-stage charging function that automatically adjusts the charging mode based on the battery's voltage. It provides efficient and rapid charging. If the battery is in protection mode due to the BMS, simply connect the charger, and the battery will activate in 3 seconds.

FAQ
What charger should I use for LiFePO4 battery?
To fully charge a 24V LiFePO4 battery, you require a charger that provides a voltage between 28.4V and 29.2V. Using a charger with a lower voltage can still charge the battery, but it will not attain a full 100% capacity.
Can I charge a LiFePO4 battery with a trickle charger?
Trickle charging is unsuitable for lithium batteries. Charging a LiFePO4 battery with a trickle charger not specifically designed for this type of battery could result in overcharging or damage, as lithium batteries have distinct charging requirements compared to traditional lead-acid batteries.
Can I charge LiFePO4 to 100%?
Yes, it is possible. However, charging a battery to less than 100% and avoiding complete discharge consistently enhances cell longevity. Similarly, keeping the state of charge (SoC) within the 20%-80% range significantly extends the lifespan of lithium batteries. Power Queen deep cycle lithium batteries exemplify this durability, enduring over 4,000 deep cycles at 100% Depth of Discharge (DoD), more than 6,000 cycles at 80% DoD, and exceeding 15,000 cycles at 60% DoD.
Is it OK to leave a lithium-ion battery on the charger overnight?
It's generally safe to leave a lithium-ion battery on the charger overnight, especially when using chargers such as Power Queen lithium battery chargers. These chargers are designed to automatically stop charging once the battery reaches full capacity, a feature common in most modern lithium-ion chargers to prevent overcharging.
How to choose the right charger for my LiFePO4 lithium battery?
It's essential to verify that your charger supplies the correct current and voltage for charging LiFePO4 lithium batteries. For example, using a 24V charger with a 12V LiFePO4 battery is not advisable. It's crucial to use a charger designed specifically for the battery's chemistry. Moreover, when charging LiFePO4 batteries, avoid using standard lead-acid chargers that may include features like desulfation or dead battery mode, as these can potentially damage LiFePO4 batteries.
