Neoprene Battery Covers for Ebikes?

[jason]

What do people think of Neoprene battery covers for ebike batteries? Anyone using them?

For example I have found the NC-17 here: https://www.amazon.co.uk/NC-17-Battery-Protector-battery-Neoprene/dp/B01M5B4W4D and the Fahrer Bosch battery cover here: https://www.amazon.com/Fahrer-Bosch-Bicycle-Frame-Battery/dp/B00J4LUQRS

Usually you want the battery to be cool when using or charging it. However in cold weather it may be more appropriate when insulation is required. You definitely want to take the battery out of the cover when charging it or at least unzip the bag...

They're only really suitable for temperatures below 15°C. As stated above make sure to take the battery out of the cover while charging. I would also check the battery when riding under strenuous conditions, eg. Uphill, at high speeds or under high loads. If the battery heats up under these conditions then you want to take the cover off so that it cools down.
