12V 20A/24V 10A AC-to-DC LFP Portable Battery Charger

DESCRIPTION Supports lithium batteries with activation to exit BMS protection safely. 100–240VAC input; includes ring terminal & alligator clip cables. 3-stage intelligent charging with over 89% efficiency for lithium cells. Five protections: short-circuit, overcurrent, overvoltage, overtemperature, reverse polarity. Plug-and-play design with fanless, fast-dissipating shell, plus bracket and screws.

The Renogy 20A AC-to-DC Charger is an automatic, portable charger intended for 12V Lithium-iron phosphate (LFP) batteries. It includes 12AWG alligator clips and outputs power based on the battery's power, voltage, and current condition. The unit's status indicator light illustrates the connected battery's operating mode and condition. The Portable LFP charger automatically monitors and maintains the battery at full charge.

Lithium Battery Activation

When the lithium battery encounters low temperature/low voltage, the BMS protection will be triggered, and charging cannot be performed. This charger provides a lithium battery activation function that quickly exits the protection mode and recharges. The charger's indicator light can remind the wrong charging status and achieves all-round monitoring and protection.

Smart Charging

This charger features a 3-stage intelligent charging system: high current (CC), constant voltage (CV), and trickle charging. It can accurately identify battery voltage and automatically switch charging mode and provide fast and efficient charging for lithium batteries; the charger's efficiency can reach up to 92%.

Strong Adaptability

The charger comes with a battery charging cable (alligator clips are recommended for short-term use). The battery charger has a wide AC input voltage range, 100-240 VAC 50/60Hz, which is compatible with AC power grids in different countries to meet the needs of fast charging anytime and anywhere.

Build-in Safety Protection

The charger has six built-in protection functions to ensure charging safety, including short circuit protection, over-current protection, over-temperature protection, over-voltage protection, under-voltage protection, and reverse polarity protection.
