[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 US makes the delivery time faster.

FAQ

Is 24V(29.2V) 20Ah lithium battery charger waterproof?

No. The 24V(29.2V) 20Ah LiFePO4 battery chargers are not waterproof and should always be used in a dry environment.

For trolling motor batteries or marine household backup batteries, we recommend pairing them with a waterproof charger to ensure safety and long-term reliability.
