Recharge your LiFePO4 battery from AC power with the Renogy Portable LFP Battery Charger. Choose the 12V 20A or 24V 10A variant to match your battery system. Its portable design makes it convenient to recharge between trips, while automatic charging and status indicators help you keep track of progress.

Choose Your Variant

• 12V 20A: For compatible 12V lithium iron phosphate batteries.
• 24V 10A: For compatible 24V lithium iron phosphate batteries.

These are separate charger variants, not selectable output modes on one charger. Match the selected variant to your battery's voltage and permitted charging current.

Features

• Designed for LiFePO4: Charging profiles intended for lithium iron phosphate batteries.
• Automatic charging: Adjusts charging operation as the battery charges, with indicator lights for charging status and faults.
• Fanless cooling: Heat-dissipating plastic enclosure avoids cooling-fan noise.
• Wide AC input: Listed input range of 100–240V AC, 50/60Hz.
• Built-in protections: Short circuit, over-current, over-temperature, over-voltage, under-voltage and reverse polarity protection.
• Convenient battery connection: Battery charging cable included; alligator clips are recommended for short-term use.

Package & Connection Details

The supplied 12V 20A package information lists one portable charger, an alligator-clip battery cable and a blade fuse. The blade fuse provides additional protection in the event of a reversed battery connection. Confirm the selected variant's supplied accessories before installation.

Battery Compatibility & Use

Match voltage and current: Use the correct variant for your LiFePO4 battery system. For the 12V 20A variant, the battery must permit at least 20A charging current. Charging time depends on battery capacity, starting state of charge and charging conditions.

Battery activation: The supplied 12V model description lists a lithium battery activation function for compatible batteries in BMS protection. Follow the battery and charger instructions, and do not use activation to bypass temperature or other safety restrictions. Only charge within the battery manufacturer's permitted temperature range.

Connection: Follow the selected charger's manual for polarity, connection sequence and AC power requirements. This is an AC-to-DC charger, not an alternator-powered DC-to-DC charger.

Specification note: The source description mentions 12AWG alligator-clip leads, while its specification table lists 14AWG terminal size. Confirm the supplied cable and terminal requirements in the model-specific documentation before choosing replacement wiring.
