QWW48V13AH 1400W Electric Bicycle Battery with Waterproof Bag and Charger

Good quality quick shipping good customer service

This battery does not give me enough mileage to be worth the money I paid for it. And as the power Runs Out the bike gets slower and slower. Not a great battery spend the extra money on a bigger one

The battery provides the power needed for my son's 1000W electric bike. Acceleration is awesome! He rode on just battery power for over an hour, and the battery's capacity was still registering at three fourths (his e-bike conversion kit came with a crappy, non-LCD display, so we don't have a good indicator of battery power; just four LED's).I'll update again if something goes wrong, and I'll try to remember to update over time even if things go well.

- Great quality battery mount and plug and play with my old battery mount- Great power compared to my 48V battery reached speeds of up to 70km on a decline crazy!!- Huge ammount of torque from this battery allowed me to go up a steep grade at 50km!- Good quality charging block and very cheap price for the A quality of battery compared to competitors

I have only been out twice with it. Do to weather. Works great with my motor. 25 mph up a good grade. I am 200lbs no pedaling. 35mph on mostly leave road. I plan to ride it to work when it warms up a bit more.

This company sucks big time , battery only worked for six months then cut out they don't stand behind there product. They won't give me a refund I'm seeing anybodyelse have problems with this company ?? Let me know

I either buy the cheapest or I make my own using batteries of my choice. This seems well constructed, and the performance is no worse. It is what they claim it to be. In the three years that I have been building and using bicycle electric assist set ups I have yet to wear a battery out.

My granddaughter's electric bike battery died suddenly on her and this is her only transportation to school and work, so we quickly ordered a new battery. It wasn't supposed to come until some time next week, but it came today!! We are so excited that she'll be 'up and running' again on Monday. Thank you so much!!

Battery performs as described, interms of power output, but capacity is lacking. I'm getting roughly 30km of range... not great. After 300 cycles battery has lost 10% capacity... not good. I think the 18650 cells that comprise these Bbattery packs are each rated below 2500mah. Battery pack may be closer to 11ah not 14ah. Take all this in when making your purchase.

Does the same job as original and more (more amps). Had a RadRover bike and needed a new battery.Easy to change and install the support battery plate on my bike. Price is decent. Very happy.

BAD COMPANY, BATTERY WORKS SO FAR. BUT IT CAME WITH A CHARGER WITH THE TOTALY WRONG PLUG CABLE. THIS CHARGER IS TOTALY USLESS. I COULD USE THE CHARGER FROM MY OTHER BATTERY BECAUSE THIS PLUG WAS THE SAME. I WAS JUST LUCKY. OTHERWISE I WOOD HAVE TO FIND AND BUY A MATCHING NEW CHARGER. THE FIRST BATTERY I GOT A 2O AMP BATTERY 48 VOLT FROM "WALLEN POWER". AND I WILL BUY BATTERIES AGAIN ONLY FROM THEM IN THE FUTURE.
