Is it worth it to use a down tube insulation in the winter to protect the battery from 20-40 degree temperatures? Or colder?

Wondering if it actually does any good to buy or make a neoprene cover for the down tube/battery for the winter temperatures and charge longevity and battery longevity longevity.
Thank you.

I use one that a mate gave me. Not so much for the battery but more as a frame protector and it's easy to undo and get rid of all the mud.
it's quite a handy thing to have on the bike.
I doubt that you manage to keep the battery warm but keeping a bit of wind chill off it can't do any harm .

Concerned about the bike on the hitch rack while driving down the road, or stationary and while ridin.

This is mine. I think it's from eBay and I use it during the winter months

Is there any difference between having 30f temperature wind moving at 60-80mph vs stationary for a hour or 10hrs vs riding in 30f temperature?

Wind chill will not lower temps for inanimate objects to below the ambient air temperature. A cover may protect from spray and chemicals on the road but your battery will stay at air temperature. Wind chill affects humans and animals.

Any idea what you'd call that @Bones ?

Looks like just what I'm after. I use velcro straps around my battery which means the rubber cover doesn't seal 100% and I'm concerned water will easily get in, a similar cover to yours should sort that out.

Sorry no . I've had this for a couple of years now and the only small tag on it says xlg.
I have managed to get the Bosch 500 battery to fit in the frame and like you I use a large velcro strap and this cover does a great job of keeping it fairly watertight.

Amazon seem to have a number of neoprene downtube covers, perhaps start from here and find one the right size?

Thank you, I will have a search

I thought the same thing! Someone at work said they had battery issues after keeping the bike in the garage over winter

Neoprene won`t help.

Neoprene won't help with what?

 

[Bndit]

keeping battery warm

keeping battery warm

Can help to slow battery temperature dropping to ambient temperature. hth.

 

[Bndit]

Sure, and it keeps your battery nice and warm on winter storage.

Got one from Amazon. Don't know if it helps but the theory is good. It collects the mud and had to be washed after a wet ride. Be better if it had a smooth waterproof outer

Neoprene is waterproof (not porous) so I think what you have is not made of neoprene.

I doubt there are benefits of having a cover to keep the battery warm. Especially with aluminium frames as they are just a huge thermal bridge.
