When charging, first connector to the battery, then connect to AC; after full, cut off AC,  then pull the battery plug. If you pull the battery plug first while charging, especially when  the charging current is large (red light), it is very easy to damage the charger. 2. LED display after turning green, then charge for 2-3 hours. 3. Please do not run out of battery power, then charger.

## Features

- Output 54.6V 3A, World Wide Input Voltage 100-240VAC 50/60Hz, red light -- charging, green light -- charge OK, it stop automatically when the battery is full
- 105℃ Output capacitor, global applicable AC Input voltage.100% full load aging test, Internal EMI filter, ripple minimum. The precision current between ±0.1A, the voltage tolerance is ±0.1V, absolutely not virtual marking.
- The charger Built-in simply fan, with radiating fin surrounding the board, dissipating the heat through the shell, So some hot on the shell when charging is very normal, but it is durable.
- The Charger protected: Battery detection function / reverse polarity protection, Our product is equipped with ‌thermal protection‌ and ‌overload protection‌ to prevent charging issues caused by overheating or excessive current
- Replace your broken charger or add an extra charger to charge in 2 locations without taking the original charger with you
- The one Lithium battery is normally 4.2 volts max, so 13S boards * 4.2volts = 54.6 volts. That way you can't overcharge the batteries as long as they are rated correctly. Make sure you have the correct female power connector for this: 5.5 x 2.1 mm plug

## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Works great on Addmotor electric bike batteries....  but green charged light burned out!
  

*by T***W on Reviewed in the United States on May 11, 2020*

Needed a charger for our Addmotor electric bikes and this one works really well, one concern I had was it is a LOT lighter weight than the stock charger, but it does a great job at charging the batteries to full charge at a fast rate, plug it in and red light shows it's charging, green light when the battery is fully charged. However the green light quit working but it still charges the battery great and well, basically if the red light goes out then you know the battery is fully charged so green light being on is not a big concern for me.

### ⭐⭐⭐ 







  
  
    Hot charger melted a hole, and stopped working.
  

*by K***S on Reviewed in the United States on May 5, 2019*

But it lasted me 7 months so i cannot complain too much. Im buying another until i can find one with a fan

### ⭐⭐⭐⭐ 







  
  
    Seems to work as advertised
  

*by 9***N on Reviewed in the United States on May 2, 2019*

While I have only used it once, it worked as expected.  One enhancement which would be nice is if it indicated how full the target battery was via an LED array or a blinking LED or a colored LED.
