电瓶护套 2. Battery Sheath
A protective sleeve wrapped around the battery will protect the battery well and prevent the battery from being affected by high temperatures. Too high a battery temperature can easily lead to shortened life. It cuts off the heat transfer between the engine and the battery and plays a very good protective role. Then fans will ask, why is there no sheath for the negative electrode?
You do n’t see the positive sleeve less than a red sleeve, and a black sleeve is placed on the upper frame, because the negative pole is directly connected to the frame. If the positive pole hits the frame, the battery will be short-circuited. , The negative electrode does not have this problem.

It must be raised, and the sound of passing the speed bump has the rush of high-end cars. This can also be done by yourself.
