KFFKFF 12V 20A LiFePO4 Smart Charger 14.6V AC-DC with Anderson Connector, LED Display & 0V Activation — Compatible with 12V LiFePO4 Deep Cycle Batteries for Boats and RVs

Overview: Designed specifically for 12V LiFePO4 batteries, this KFFKFF AC-DC smart charger delivers a 14.6V DC output and up to 20A charging current. It can recharge a 100Ah battery in about 5 hours. Note: not for use with lead-acid batteries. Smart 3‑Stage Charging: The charger automatically manages charging with a Constant Current (CC) stage for rapid charging, followed by a Constant Voltage (CV) stage to avoid overcharge, and a final Full Charge maintenance stage to preserve battery health. An LED display provides clear, real-time indication of charging status. 0V Activation for BMS‑Protected Cells: Built-in 0V activation lets the unit safely revive batteries that have dropped to very low voltages or entered BMS protection mode, enabling charging without external tools and helping prevent damage from prolonged low-voltage conditions. Safety & Reliability: FCC-compliant, the charger includes multiple protections—overtemperature prevention, reverse polarity protection, short circuit protection, and overvoltage defense. A built-in cooling fan helps maintain stable operation during extended charging cycles. Convenient Connection: Comes with a 1.4 ft 50A Anderson-M8 terminal adapter cable for easy plug-and-play hookup. Ideal for use with RVs, boats, golf carts, solar setups, and other lithium-powered applications.
