For the price, you can't really go wrong. I have run 5-6 charges through it so far, and after the first 2-3 now I'm getting the range I expected. After the first charge, I was worried I got one of those packs with half the capacity, but hindsight tells me it was just hard terrain and I was really pushing the motor in some spots. Today I road about 18 miles on old railbed, so about as perfect for an ebike as exists. I averaged 14-18 mph and when I was done, the cheap-o battery display that came with my motor kit still had 1 bar left on it. (out of 4) 750w BBS02 motor kit. Over-all --- if you're worried they're a scam.. mine wasn't, I'd suggest one of these to anyone that has the physical space for it. Check your mounts though - it doesn't line up with some Trek MTB frames, I had to modify some stuff. Read full review

The battery charges Knisley and performs well. The only negative thing I would say is that I’m not getting any power at the USB port. I did buy two of these batteries as I have converted to bikes to electric and neither one has power at the USB port.

Received this product sooner than promised and was easy to install on modified bike rack. Pleased with discharge performance so far. Have not tested for 12.5 Ah but range on a converted 24" cruiser looks to be about 40 miles at 10 to 12 MPH on common asphalt bike trails. Can't speak to durability yet but confident so far.
