Power Queen 29.2V20A LiFePO4 Battery Charger for 24V LiFePO4 Battery
C$149.99
C$309.99
[Specifically Designed For LiFePO4 Battery] Power Queen 29.2V 20Amp LiFePO4 Charger is uniquely designed for a 24V LiFePO4 battery, adopting the 2-stage constant current/constant voltage (CC/CV) charge technology which enables full charge of the battery to 100% capacity automatically. Besides, the charger has an exclusive pre-charge mode which is designed for activating the 0V battery protected by BMS. Simply connect the charger to the battery to initiate a restart which sets you worry-free.
[Saving 1/2 The Charging Time] With input voltage from 100V-240V, which maintains a stable voltage accuracy at ±0.2V (approx.29V to 29.4V) and affords output constant current at 19A to 21A. It enables charging a 24V battery pack instead of charging a single 12V battery individually one by one. Only needs 5 hours of fast charging time to fully charge a 24V 100Ah battery pack compared with a 12V 20amp charger which needs 5hrs+5hrs=10hrs to fully charge it. Save half charging time and disassembly steps.
[Easy Operation & Intuitive LED Light] Just an easy connection to the LiFePO4 battery by using the included battery alligator clips. Then plug in the input cable to the charger and connect it to the input power, the battery will start charging your battery. The LED light provides visual charging state feedback and diagnostic information and displays the charging status.
[Reliability & Multiple Protection] The advanced circuit design and strict production process according to the IS09001:2008 quality management system make the charger more reliable and with long service life. Providing multi-protection from over-temperature, output short-circuits, output over-voltage, and reverse polarity connection, to ensure safe use.
[Professional Warranty Service & Faster Delivery] As a professional seller, we contribute to providing higher quality products and better service to our customers all the time, so we promise a 2-year warranty and quick response customer support within 24 hours. And the local warehouse in the CA makes the delivery time faster.

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.
