How do you convert 20v to 12v?

You can use a resistance in series with 20-volt source to drop down the voltage to 12 volts. You can use a resistance in series with 20-volt source to drop down the voltage to 12 volts. You can drop down the voltage by use of 7812 regulators or by Zener diode voltage regulator.

What does 12v 20v mean?

The main difference between 12v, 18v, and 20v tools is their power; the higher the voltage of the tool means the more influential the tool is, so here the voltage is 12, 18, and 20 volts, indicating the 12v tool has less power compared to the 18 and 20-volt tools.

Can I charge 2 12V batteries in series?

Series Batteries. Charging time will be the same as charging a single battery. Charge more than five batteries by connecting one 12-volt battery charger across each battery in the series, as if each battery were the only one being charged. Charge all the batteries at the same time.
