Product Introduction

1.Efficient Charging
Adopting advanced switching power supply technology, the charging efficiency is as high as 85% or more, shortening the charging time and reducing energy consumption.
2.Constant voltage and constant current charging mode
The charger works in constant current (CC) mode until the battery voltage approaches the set value (14.6V), and then switches to constant voltage (CV) mode to ensure the safety of the charging process and avoid overcharging.
3.Intelligent temperature control 
The built-in temperature sensor can monitor the charger temperature in real time. When the temperature exceeds the safe range, it automatically reduces the charging current or suspends charging to prevent overheating.
4.Multiple protection functions
· Overvoltage protection: When the voltage exceeds the safe range, the charger automatically cuts off the power to prevent battery damage.
· Overcurrent protection: When the current exceeds the rated value, the output current is automatically limited to protect the battery and charger.
· Short circuit protection: The charger has a short circuit protection function to avoid dangers caused by short circuits.
· Reverse connection protection: When the positive and negative poles of the battery are reversed, the charger automatically stops working to avoid damage to the battery and charger.
5 LED indicator lights
The charger is equipped with LED indicator lights to display the current charging status:
· Red light: Charging.
· Green light: Charging completed or standby.
6 Voltage and current can be calibrated
· The adjustable resistor VR1 inside the charger can be calibrated between 10-17V
· The adjustable resistor VR2 can calibrate the current between 16 and 20 amps
· The charger needs a battery voltage of at least 6V to work
· The charger can directly output voltage and current for use as an adapter

Charging time

· The 14.6V 20A Lifepo4 battery charger is designed for fast charging of 4S 12.8V Lifepo4 batteries and can charge 4S 12.8V Lifepo4 batteries at a rate of 20 amps.
· With a maximum voltage of 14.6V and a rated current of 20Amp, it can fully charge a 40Ah Lifepo4 battery in about 2 hours and a 100Ah battery in about 5 hours. A 120Ah battery can be fully charged in 6 hours. For smaller batteries (<10Ah), we recommend using a 10A charger. All Lifepo4 batteries should be charged using a charger that is compatible with Lifepo4 batteries, such as this one. Using other types of chargers to charge the battery will reduce the performance and life of the battery.

Frequently asked questions

1. Not working
· Check if the AC input voltage is 110 or 220V
· Check if the input AC terminal is connected correctly and if the fuse is damaged
· Check if the output connector is connected correctly, if it matches, and if the fuse is damaged
· Check if the BMS system is protected
2. How loud is the noise
Since there is a fan inside the charger, the noise is about 40-60 db
