H HAILONG 36V 48v 52v 60v Electric Bike Scooter Lithium Battery with Charger,2A Charger and BMS for 250W 350W 500W 600w 800W 1000w 1500w Motor

I am extremely happy that this battery performs just as I needed. It extends the range of my commuter by +/- 15 miles. I felt the cost was a touch on the upper end ar $117, but it has more than paid for itself.

Battery is smaller than stock one ---cut packing foam for spacer on top --Seen in photo. Had to transfer power plug from old battery to this with two blue butt-connectors . Also used new battery charging wire/plug ! Drilled a 7/16 hole toward left front down low . Siliconed it in place . Put a vacuum cap over it ! Used the charger that came with battery .

Charger is good. Easy to install and connections are solid. Added electrical tape around the main connection because it does spark. Battery charged and stopped and 42.2 volts. Sadly it didn't work on the bike. Seems like something internal in the battery shuts it down above 10 amps (partial throttle) within seconds. Makes the bike a heavy e bike with a battery that won't provide the power:/ Has no issues when the bike wheel is in the air modulating from minimum to max speed. Just not good for much load (amps) at all.

I hit 32mph on a flat road with this battery fully charged on my 2000 watt 29” e-bike I weigh about 230lbs. The mileage is decent probably 25miles before the cutoff kicked in. Charger gets hot to the touch so that part is sketchy but other than that the battery performs great

I bought this to upgrade my sons MX500. The lead acid batteries ran their life and it was time to replace them. Just changing the batteries saved 18lbs.It was super simple overall. Took about 40 min from start to finish.The included wire was soldered to the old battery connection. I labeled them A and B. I disconnected the old charger but left in place.I had to remove a few Allen head bolts to get the batteries out and the controllers I left the mounting bracket on the controller.I removed the batteries and using a hammer banged out the front lip on the battery tray. Using the included foam from the new battery, I cut a pad out and punted the battery on it. 3 big zip ties holding it down. Then, the old mounting bracket with the controller sits perfect across the battery. That is zip tied to the 3 zip ties. I replaced the outer cover and using the old charging cable . Remove the screw with the spring on it and it creates a holes. Run the charging cable through it and your good.As far as run time, my 10 year old 85 lb son, could ride about a 1/2 mile and the batteries would go to low. Now, he can ride that same half mile loop at least 10 times. It’s winter so we are still testing. But overall we went from 36v 12 amps to 36v 20 amps.Very happy overall.

I love this battery good capacity came with charger I've used it about a month no issues at all. Follow safe charging and storing and you will like this battery too not a paid reviewer just love this battery. Shipping took a couple weeks came from china.

I bought an electric bike and a year ago. Like many things, life got in the way and I finally lost the game of keeping the battery charged and not letting them completely discharge.I decided to give this battery a chance. First, it's a cube, not a rectangle line my pervious battery but it fits in the bag just fine. It took about 1.5 hours to chagrin and powered my bike on all power levels without any issues. That's all I have for now but I promise to keep you updated on the longevity.

Gave my ebike a massive boost to speed and distance.
