Worked great for e-bike battery
Simple yet effective! Seems solid.Update as of 5 Aug 2022: it is very solid. Have had ZERO issues with using it inverted for the battery mounting. Very impressive

I have a vintage frame for holding my electric bike batteries...
...so i knew I needed to trim the clamps it came with. But I REALLY appreciate that this actually came with the bolts that is not pictured. THANK YOU!!

Great for ebike battery
If you do not want to drill frame for mounting ebike battery, get these! Work perfectly, and holds 48v shark pack.

More secure than built-in water bottle mounts.
I'm using this product to mount a very heavy e-bike battery and it works great! Thanks Grin!
