Question about P/S and chargers

[genexis]

With so many chargers in the market, and most of the them requiring a 12V DC regulated power supply. But then, each 3S LIPO cell is 4.2 X 3 = 12.6 V

How can the 12 volts charge the 12.6 votes to max capacity ?

Which of these chargers have a inbuilt transformer or something inside that will charge them fully ?

It difficult to explain the electrical circuit involve. But most if not all should be able to charge cell w voltage higher than the input voltage, all had been taken care

Example, triton can charge Nicad/Nimh up to 25 cells.... and that is talking abt 30V

Cheers

There is something called the Transformer.

Either a setup transformer or step down transformer.


Like US is using 110V supply and SG is using 230V supply. U will need to get a transformer to use products from either country if its not the same.



Therefore there should be a transformer inside ur charger that will either step up or down the output voltage.

There is some circuits inside the charger that increases the voltage when charging higher voltages.

For the charger to charge at higher voltage, it comes at the price of increased current consumption.

Let say input voltage 12v, charging 24v at 5 amps, the consumption would be 10amps at 12 volts. The formula is V=IR.

I hope u are confused!

Yep, so the 2nd part of the question, does all these chargers all have transformers ?

The triton and schulze have, I have not used the others, so cannot comment.
