DIY How to make a battery, Power Bank 12 Volt

Описание

DIY battery. Very powerful. May start the car engine. It can work as a backup source of energy. Compact. Easy. Fits in a bag or pocket. And it costs less than 10 dollars.
Do it yourself. It is always useful in difficult conditions. If there is no electricity, if the battery is discharged, it will always help out. Watch the video, learn how to do it. This is not difficult. Only 1 hour to manufacture.
No special knowledge needed. No complicated equipment needed. Only your hands and 1 hour of time. It will last up to 25 years. A very reliable source of energy.
