Batteries that every vehicle is keen on.
The essential role of the 12V lead-acid battery.
The job description of the 12V battery does not fit on a business card. It is responsible for so many things; nothing works without it. It provides the necessary energy to activate the safety relay and connect the high-voltage battery to the board net and electric engine.
