54.6V 3A Charger 48vdc Output 54.6V 48Volt Replacement Charger Universal Battery Power Supply Adapter for Universal Battery 13Series 25Ah 23Ah 17Ah 20Ah 14Ah

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.

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

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.

So I write this review with some trepidation, and Ill tell you for why. I really like this charger, its small, light weight, has a long power cord, a built in fan, and for the past eight months has worked fine. The only problem is that recently the fan stopped working. The charger is still charging, but it does get hot without a working fan. So i'm not sure how long this charger will last now, although I did purchase a two year protection plan.Update: So the charger no longer works. I sent a message to the seller, told them about the problem, and they agreed to send me a new charger, which I received yesterday.

I bought this because it says it has a cooling fan in the description, it does not. I should have payed attention to the review that said it overheated and melted. Now I know why, no fan.

I bought this to charge my Sondor's Fold X. The charger it came with died, I bought this, and it just worked.Couldn't be happier.

Not bad. It charges the battery at a slow rate because its 1.5amps but I can't tell u it takes about 8-9hrs to full charge and will let your battery last longer when in use.

The battery charger works as described and advertised. I had to replace the original battery charger that came with my e-bike battery.
