I think that a protector has two uses:

Protect the battery when the bike is parked out in sub zero temperatures - keep the temperature in the battery while you are stopped for that hot chocolate.
Protect it from wind chill: -1°C = -13°C with wind chill
You are only protecting capacity/range not the batteries from damage, they can stand those temperatures as per manufacturers specs.

It will be useful in places like Germany and Holland where people ride a lot in sub zero temperatures to keep range from falling off the cliff. Last winter I was seeing -15 to -20% range on very cold days.

Is it worth the price? No, you can probably make one yourself from a retired neoprene sailing suit like the one I have rotting away in my closet.

.... while you are stopped for that hot chocolate.
What hot chocolate?...... it wasn't me ...... I was never there ...... you must be mistaking me for someone else :rolleyes:

I'm a hardened pedalist me, dedicated to the cause. No time for hot chocolate, or cakes..... or hobnobs.... or maryland cookies/bourbons/garibaldi's/custard creams etc :D

My battery cover silenced any rattling noises my battery made in its cradle, the squidgy material seeming to help to hold the battery gently but firmly in place where it was squeezed against the frame. Whether the extra insulation does any good I am not sure.

I'm guessing my £35 neoprene cover will not serve any purpose for me.

I ride casually from spring to mid autumn. I don't ride if wet. Do like cross coutry trails which I can see will most probably cause rattling.

So the cover is only being used to prevent rattle!

Would a cover be harmful if in hot days preventing battery from cooling??

Is it worth it or should I get rid.

I keep my neoprene battery cover on in the summer with no ill effect that I can detect. I do now ride in eco and off on the downhill bits off road, but do now use the middle assist of the three I have available on my 2015 yamaha system on the steeper uphill road riding bits,

What are the benefits of keeping cover on in summer?

Why would the battery cool?. An ambient temperature of around 20 is perfect for the battery. A

My neoprene battery cover combined with correctly adjusted battery mount cradle screws holds the battery very securely and adds some more shock absorption to the way the battery is held making everything very quiet.

Although I have not taken advantage of this benefit it would help protect the battery from impact.

Bosch recommend batteries are charged and kept at room temperature.

To add to that, it probably helps to keep the lock free from dust and muck as well.

Stops sunburn :rolleyes:

With the weather the way it is I thought exactly the same thing! A battery cover will keep heat out if you are parked in direct sunlight.

Can a battery suffer wind chill?
It does not perspire so I would not expect it to experience wind chill.
