In the bar, we put the battery screen engine, then the flat washer, the flat washer and the lock washer, we put the whole screw tightly, but don't be too tight, so as not to damage the thread, tighten the power to be held motionless by the woven mesh. It can be converted into a butterfly with a screw. This solution does not require tightening the key to prevent over-tightening.

Protection: Remember the fuse, which can be mounted on the motor cable or between the motor and the battery. If any short circuit occurs or current consumption is too high, the fuse will operate and protect our health and equipment.
