downtube battery

[SirBikesalot]

Hi there i have a upp 48v 24AH downtube battery and the 2x screws for the bottle holder isn't enough it wobbles a little meaning in time it will get looser or even brake the thing my battery clips in to what is the best way to make it more secure i just don't want it looking a mess i do have a couple idea but i would like to see what you pro say about this. Thank you for taking the time an wish you a blessed day!

Have you tightened bolts enough? Use any means available to secure battery. Rivet nuts, velcro straps, extra bracket etc. 48V 24Ah must be massive.
Battery can't wobble.

UPP don't have good reputation. Ideally charge and store outside.

Yes with the UPP do make sure it is properly secured , there have been issues in the past with battery build quality .

I have used a Wolftooth B- Rad mount base for down tube batteries, but tbh any heavy battery on a down tube fixing needs extra strapping support to prevent sideways wobble /jolting. A couple of decent cam buckle type straps or a couple of nice velcro straps to tie down for rigidity.

A couple of examples.

Tbh bike conversions using exsisting bottle rivnuts aren't designed to take heavy 3.5kg + batteries , the issue is vibrations and the sideways movement of the battery mass.
Extra strapping is the way to go to make sure of a nicely securing the battery on a bikenot designed for one.

If your battery is shaped like mine a few cable ties joined together in a large loop can secure the battery to the tube and slip off and back on again when the battery needs removing..

Thinner cable ties have more elastic stretch to slip on and off again if concerned with their strength double/triple up

I've found old fashioned toe straps are cheap and effective. Link two together for a larger battery.
