Hailong Ebike Battery 36V 48V 52V-10AH 13AH 15AH 20AH with 3A Fast Charger 30A BMS, E-Bike Scooter Lithium Battery for 0-1500W Motor.

Perfect fit. Mounting was very easy. Charge lasts longer than expected. If I ever need a new one I will buy this one again.

The battery was shipped in a timely manner. It came with everything needed to install. Installation was easy by following the instructions. I am using it in the pedal assist mode and it works flawlessly. I run it up to 30 MPH without any problem. The battery has stayed fully charged for a thirty mile ride without any loss of power. I am very satisfied with this purchase.

Excellent charge battery. Leave switch on while using charger for better results.

I ordered this battery for a second battery to my e-bike ! It’s works perfect. All summer I was using this battery. It’s making my range much longer and my e-bike faster! Definitely I can recommend this. Delivery was in time!

Battery Dimensions listed DO NOT INCLUDE battery cradle/base - THEREFORE this battery does NOT fit into EITHER mount on my EBike - and IS NOT RETURNABLE. Just wasted over $200 - and can't get it back... all due to lack of proper information by seller on Amazon advertisement.

Large capacity and charges fast, lasts a long time and very easy to mount, would recommend to buy again.

I bought this battery as a backup for my ebike and turned out to be better than the original what came with the bike. Getting about 10 miles more on pedal assist and this battery pack is more than 1/2” taller than the original so for sure has larger capacity. Probably I’m buying an other one because my original battery what came with the bike, one day just quit a few miles from home, so I had to disassemble the whole thing because they put the fuse on the bottom of the case and siliconed the battery pack on the top of it. So the battery from this seller is more durable and better quality

Great battery, last long and powerful, if I would need to buy a new battery this would be the one.
