36V 48V 52V 60V 72V Ebike Battery 10AH 15AH 20AH 30AH Lithium Battery Pack for 250W 750W 1000W to 3500W Bafang Voilamart AW Ancheer and Other Motor

My boyfriend and I both ordered one of these batteries for our electric bicycles. The batteries have a great life and installed super easy. One of the chargers, however, had a short or something and would not charge after a use or two. I am still giving a 5 start rating because I sent a message to the seller, they immediately responded and offered to send a replacement charger. It was coming from China so they informed me it may take 10-12 days to arrive, but we had the replacement in less than a week. They could not have been easier to deal with.

Battery companies that don't lie about the internal components are very hard to find!!! This company is incredible!!!! This battery is very powerful & dependable. There customer service is beyond outstanding!!! There was an issue with first battery, it was damaged during shipping, I am quite sure. This beautiful company and customer representative replaced with zero hassle. I build High powered e - bikes. I have been riding for 54 years. The last build is the most gorgeous bike anyone has ever laid eyes on. And it is faster than most supercars. It is a rocketship!!! The wind tries to rip off my helmet. The front fender ripped right off on my way home from work. I obviously built a better one. This rocketship of a bike is powered by this battery!!!! I am pulling 8- 10,000 watts, there is no need to go any faster. It is the most fun vehicle I ever owned + I had a lot. Thank you for letting me share. Trust me, I am not paid to say anything+ I never leave reviews. Normally way to busy to bother, but also never this impressed by anything!

The motor slowdowns on hills is eliminated, charges faster, runs longer.

HiOne big plus: You now get a 3A charger rather than the 2A that is currently shown in the listing. Battery took just about 3 hours to charge when it arrived. That's pretty normal since they have to ship them "empty" to comply with various regulations.First pass capacity test came up with 93.13% on one battery and 92.64% of rated capacity on the other battery. Charge them overnight and I got 97.88% and 97.21%. Testing was done with a simple 180W capacity tester bought off Amazon. Calibration of the tester was verified against a Fluke meter. Seems like an overnight charge did them a bit of good.Ideally on a brand new battery, you would like to see a percent or two *more* than the rated capacity. The test is certainly accurate to < 1%.The BMS cuts out a bit above 27V. Both batteries cut out at the same point. Nice to know it works properly and does not let the batteries go insanely low.Is a couple of percent capacity worth a star? In this case it was ....Would I buy them again? Sure I would. They appear to be pretty good batteries overall. They just don't *quite* meet spec.Bob

I am impressed with this battery for my ebike. I was unable to find an original replacement as the company that made my bike is no longer making them. This battery has roughly the same aH capacity as the original so I gave it a try. I was able to make it fit into the original clam shell case. The only caveat was with the power connector. The correct connector came with the battery though. A little bit of soldering and I was in business. The charger that came with the battery is very nice as well. It has an indicator LED to tell you when it’s charging the battery and when charging is complete.This battery has been in service for several months now with no issues. I can go about 30 miles on a charge. Perfect for all i do !!

This batter fit right into my son’s four wheeler. It’s compact and lasts a couple hours of riding.

This battery works good had it for a while and it last long this company is Amazon they are always helpful I’ve tried those other cheap battery brands and they suck but btr power is the best…

Had issues with original battery after left charging during an unexpected rain. Found this one size compatible with my Electric Bikes Model C. Installed and running strong.
