Received my item an waiting till spring to try out

Mounted easily. works as advertised. Wish there was a better way to rout the connecter cable. Have it covered with Gorrila tape so I don't trip over it when I get on the bike.

This is a handy way to have the extra power for bike use when camping off grid for extended periods. Unless you have an elaborate solar power setup, it takes quite of bit of time to totally charge up the larger batteries. It adds extra weight to the bike, but that's not a big issue for my particular use. It would be a smart idea to drill and tap a couple of holes in the frame to be able to clamp the electrical cable down, so it's not able to be snagged by brush or your foot. I ended up buying the cheaper extra battery because in haste , I didn't review the options close enough. Its not even worth trying to exchange it because of the return policies. I think that selection process could be a little more easier to understand if it were more obvious that there are two options of battery quality. I'm happy with the outcome, and know I have plenty of battery power to get me around before I have to charge everything back up. I use mine for better fishing access and exploration when camping, i don't use the extra battery a lot for just doing errands and exercise trips, the main one ( 17 AH ) does fine for that.

Fits perfectly and functions/meshes perfectly with the standard battery as one. The only possible weakness are the 4 firnished mounting bolts which I think should be 1/8" longer to provide more threads screwed onto the frame. So I just got longer bolts to make a more solid connection. Also the battery electrical wire connection to the frame mount is bent into what I consider to be too-sharp an angle that may weaken over time...possibly the frame socket could have been located 2" lower!?

The battery was sent expeditiously, well packaged and complete as described, and included a charger which can be used on my Juggernault Ultra Duo also. However, my range increased only about 11 miles which is not much ( I had expected ~20 miles more). So possibly not cost effective for $400 more... you can decide if it's worth the additional $$s for you.

Works Great!

Installed correctly, but no indication if they work or not. Nothing on the computer screen. Rode 37 km with both turned on but got down to 2 red bars, just the same as if I only had 1 battery. Used pas 1 100% of the time. No instructions or advice on what to expect from the company and no easy to find (did not find any) links to show how they work.
