I am pleased with rhe new battery. I received it very quickly. The only other comment is that the power indicator on the battery doesn't work, it reads fine on the screen so its no big deal.

Replacement 15ah upgrade battery
Our 2 year old battery didn't go bad, it fell out of our RV onto concrete and broke. The upgrade battery will be great for us as we have 2 Hammers and I weigh 80 pounds more than my wife. So the extra battery life will be great. While the battery is a direct fit, I had to adjust the slide and grind a little bit from the top. We already noticed that the slides were adjusted for each battery as our old batteries were not interchangeable. No big deal. Love our Hammer bikes!!

very helpful...
I needed a controller and a battery for my Fat Tire Hammer electric bike. The controller was out of stock but they put me on a list and emailed me when it was available.
