M-Wave E-Bike Battery Protective Cover , Black

fit the Bosch 400 battery perfect

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.

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.

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

This does not fit the standard size Radpower battery. I thought it would but it's about 3 inches to short.

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.

Covers my battery and keeps it from getting as dirty

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..
