UPP (UL Certificated) 36V/48V/52V Hailong/Shark Ebike Battery for 500W 750W 1000W 1500W Bafang &Other Ebike Conversion Wheel Kit(with Smart BMS)

The 25ah with grade-a cells.To get the negative out of the way, there is no usb port. I don’t need it, but it did indicate that there would be one.In what I have to compare to, which was an Upp 20ah 30a, this thing packs an extra 20+ miles, with more zip. I’m on the heavier end (240). This took me 50 hilly miles on my first run, with a little bit of life to spare. I built a single speed, out of an old mt bike, that I fitted with a bafang mid drive. I did have a whole 8-speed cassette but the torque of the motor just chewed them up. I replaced at least 10 of them over a few years. Have had the one rear cog running for a year with no issues and barely any wear. The downside to that is, I have middle of the road top end speed and less ability to climb really steep hills on the other end. If I had my 8 speed and this battery, I could probably get through the Rockies.One other thing that I noticed is that it seemed to be a longer charge time than stated in info. Maybe 8 hours to full. The charger box gets fairly hot as well.The performance and stability of the actual battery, which was 95% of my concern, is really high quality. Range and speed with more initial torque. The build of it is very sturdy and sealed as well. I get much less shaking over rough terrain than with my previous upp battery.I feel that you could adapt this battery for use with any bike by hard wiring it. This was plug and play for me with the xt90 connector already attached.I have only taken one ride so far, so longevity pending. So far, good report.

This battery is amazing, I originally had a 48v and would go about 2 hours and have half the battery gone. I switched to this monster a 52v 24ah and this thing is powerful, I drove for about 4 hours so far and still on 5 bars full. I also got 10mph more from my bike. Strong battery and super quick shipping, ordered it on a Saturday and received it on Thursday.

Performs well on mountain bike with mid drive Bafang motor.

Reliable shipper. Came before promised dated. Battery works good.

Rufus says the description says it has a USB port. It doesn't.

Powerful and long last ing

Works great! Great customer service!

3 stars for neutral cause it doesn't work for all ebikes. Maybe should include how to program.
