Very professional and i got what i wanted power solution
The 20ah 52V is big! I guess that was predictable, as there are very few non-bag batteries that are 20ah. Even so, I just assumed it would be a no-problem fit on my Northrock XC00 fat bike, but it was tight. Only one of the bike's water-bottle mounting holes lined up with the base, and that was only underneath the wire cover at the bottom. But I secured the top very well with a couple good size zip ties. Quality seems great.
Very good replacement,had to splice the wires to make it work where the old battery was
