Battery came in quick, works as it should and as a bonus, it looks good too, all for a fair price. I've ordered a couple of products from yose power and i haven't been let down!

Fantastic price. Needed it to fix a bike that someone tried to install an aftermarket EV conversion to a regular bike. The batteries they were trying to use were not the correct type. This matced our particular application. The bike works great powered by this battery. That baby really moves!

This battery holds its charge very well and it was easy to mount on a surrey bike. The connections were easy to use and the safety key is a great feature.

This is nicer than I expected with a switch, nice lock, and USB port.I ordered a 36v but it’s actually a 42v. For my hub motor it doesn’t matter and it’s kind of nice, but the battery meter will never work. It’s so heavy because it’s high capacity, and it’s easy to slide on and off or lock, but I wish the holder was more robust and allowed pipe clamps to hold it on. I’d recommend an additional adapter to allow a more secure mount on the bike.

This thing burned out my motor. It is a very heavy battery and does keep a decent charge but I am so upset that o have to now pay so much for a new motor. This was an upgrade from the terrible 36v 8ah battery my bike came with but turned out to be a disaster instead. Not sure why it destroyed my bike's motor but it did. Also these are basic Chinese batteries you can get anywhere on Amazon but they slapped their sticker on it. Cheap Chinese battery not with its weight. Buy higher quality with a proven reputation. You will be happy you did.

Update March 27 2021After the second charge, I went for another ride that was slightly more than the 4 miles from the first ride. This time, it stayed at 100% the whole ride. It was a mix of pedal assist and. Just accelerator mostly flat but a few smaller upslopes.I have raised my rating to 3 stars now. I will do another update after the next ride out!Dimension wise, this is the same size as my old battery and was easy to install. After fully charging it, ii went for a pedal assist ride and after just four miles... yes 4 miles, the battery was just above 50%.That means I can expect a range of 10-12 miles and its totally unacceptable!Incredibly disappointed and DO NOT recommend! (see update)
