BUKNUWO LiFePO4 Battery Charger – 14.6V 20A CC/CV Charger with Anderson Connector
About this product
Reliable 14.6V CC/CV Charging
Delivers a regulated 20A charging current and 146W rated output for compatible 12V/12.8V LiFePO4 batteries. The 100–240V AC input supports convenient charging across a wide range of power environments.
Quick and Secure Connections
The Anderson quick connector makes everyday connection and disconnection more convenient, while the M8 ring terminals provide a secure connection to compatible battery posts.
Built for 12V LiFePO4 Batteries
Combining 14.6V output, 20A ±3% charging current, and 146W rated power in a compact 172.5 × 90.5 × 51mm housing, the charger weighs only 0.94kg for convenient storage and installation.
Automatic CC/CV Charging
The charger delivers a steady 20Acurrent during the constant-current stage, then automatically switches to constant-voltage charging as the battery approaches 14.6V. This controlled charging process helps provide reliable and efficient charging for compatible 12V/12.8V LiFePO4 batteries.
Clear Charging Status & Active Cooling
The two-color LED provides clear operating feedback: solid red indicates charging, solid green indicates standby or fully charged, and fast-flashing red indicates reverse polarity, short circuit, or low battery voltage. A built-in fan provides forced-air cooling to help maintain stable performance during charging.
Built-In Safety Protection
Built-in protection against short circuit, reverse polarity, output over-voltage, and over-temperature helps protect the charger and connected battery from abnormal operating conditions. Under-voltage protection and timed output shutdown provide additional charging safety.
Easy to Connect, Ready to Charge
With AC power disconnected, attach the M8 ring terminals to the correct battery posts, connect the Anderson connectors, and then plug the charger into an AC outlet. Check the LED indicator to confirm charging status. After charging, unplug the AC power before disconnecting the battery cables.
