eBay bike light battery mounting??

JGTR

Hi all, got a Solarstorm light from eBay, was thinking of mounting battery in old water bottle so it doesn't scratch frame and is waterproof - will it be a problem sealed in a water bottle with regard to airflow/heat????

Antithetical options for water proofing battery??

Thanks

I just use some silicon sealer smeared across the ends to close up the heat shrink and waterproof it, the battery is then strapped under the stem using the supplied battery carrier.

I am working on a new mount for my battery as I don't like how they intend it to be used. I also have a thing about wires.

I've stuffed mine in an old water bottle for now, i have cable tied the batteries in place by drilling the bottle and i have drilled a few holes in the bottom to let water out. I have also drilled some holes in the top so I can coil my wire up and cable tie that in place too.

This has just been a test and I plan on 3D printing something which looks a bit more 'the part'.

In answer to your question; no. The battery will not malfunction because of your restricted air flow. If anything, it will work better.

First night ride tonight, here's what I've done with the battery, it's my first effort but seems pretty good so far, could wrap it with tape if it's really wet.I've ordered some Velcro One Wrap to use instead of the tape so I can remove and refit the lights easily. Bottle is a tool bottle from Decathlon.

I'll be using a different light in future with a longer lead so the connector will be inside the bottle. When riding I have the wire between the bottle and frame to reduce water ingress.

For me it's an over complex and heavy solution to a problem that doesn't exist. I've always (last 5 years) sealed mine with silicon and mounted under the stem, never had an issue.

over complicated

Depends on the person I suppose :P

Well its more complicated than my solution at least!
