M-Wave E-Bike Battery Protective Cover , Black

fit the Bosch 400 battery perfect

Overall it fits my Bosch eBike battery nicely and protects very well against any scratches and/or from any damages. The only fault it has is that it does NOT have Thermal protection against cold weather.

I bought two of these for my Bosch PowerPack 500 batteries. They fit pretty well, although they could stand to be half an inch or so longer, because they don't quite fit all the way over the handle, but they do what they are intended to do, and for the price, they cannot be beat. I went on a 45 mile ride with them on Turbo in 40 degree F temperatures, and the batteries got about half depleted, which is what I would expect for normal temperatures. I have yet to see how well they work in the winter; I suspect they are appropriate for spring and fall but that winter will require additional insulation.

A magazine recently recommended one of these for battery care. I bought this one, but as stretchy as neoprene is, I think it's about 3/4" short for my Haibike battery. But it's one. It quiets the battery movement down. Maybe it will help keep the battery at a slightly warmer temp, and maybe it will prolong its life. My Chevy Volt works hard to keep it's battery happy..

This product says it will fit the Yamaha batteries, but it only covers 3/4 of it and will slip out of position. Booo

This "sleeve" or cover slipped on perfectly over my Bosch battery. Definitely will protect it from those unexpected downpours.

I have a Haibike XDURO ALLMNT with Bosch drive and my removable batterypack is a Bosch PowerPack 500 and this neopreme cover fit well, wanted a insulated jacket for cold weather riding to keep the battery warmer for more power.

Great !

I bought this because another reviewer said it fitted the battery on a Carrera Subway E “perfectly”. The must have a different battery to me, because it doesn’t fully cover mine. It’s about 2 cm too short to fit over the top of the battery (model EPB30A093C1) , just not quite reaching the top recessed part of the battery moulding. Also the notch for the key slot is on the wrong side. If you’re not too bothered about covering the top of the battery though, it does fit snugly over the terminal end where the battery clips into the frame, which is the important part to protect, so it’s good enough to keep until I can find something that completely fits over a Subway battery.

Contoured Neoprene Protective Cover to fit my Bosch 400w eBike battery. If you've just shelled out over £400 for an expensive bike battery, you really should pay an extra few bucks to help keep it as safe as possible. The only downside to ordering was that it took three attempts to get it right; the first received was misshapen, the second had holes in the seams but luckily the last one cover received was ok... As usual, Amazon were really good about the returns.

The media could not be loaded.  I've give it a 4 its just a tad bit to small bout an inch or so other than that its great strong sturdy material etc im still going to use it tho it just about covers the relevant bits I have the 2020 21 inch crossfire electric hybrid carerra

Cover fitted snugly on the battery (def bought the right one) but no way could battery then be fitted to frame? Seems like seams get in the way (might work better with thin retaining strips of fabric at the back rather than full coverage. A shame as these batteries do show the scuffs and scrapes. Returned

I have a new Carrera Crossfuse with the Bosch Active Line Plus crank drive powered by the Bosch 400 Powerpack.This perfect fitting cover will not only help keep the battery clean and fairly dry, but the extra insulation should keep the battery operating at its peak during the colder months.It’s true you could probably achieve a similar level of insulation using an old sock, but it wouldn’t look as good.One star lost because of the cost - a more complex shaped neoprene knee support can be picked up cheaper for instance.
