Hi fellow hobbyists,
I'm setting up something that involves a couple of linear actuators (5A each) and a winch that is normally used on ATVs. The actuators will be used to open and close a door as well as latch and unlatch a security device that's attached to the frame of the door. The winch will be used to raise and lower bikes from a pulley sy

I have 12v car battery with 150 Ampere
I want to make a circuit that allow me to get 6v from it since I need these 6v to turn some devices.
It would be okay if anyone gave me a circuit that transform from 12 volt to any other rating voltage including 6v
I want a circuit or something like that.
your help is appreciated

To charge a 12v car battery you must have at least 13v from the charger ..
The amperage only dictates how long it will take to charge your battery .
A bicycle "Bottle Dynamo" (which is a generator) doesn't give much current if you go slow ..
Bottle Dynos are spec'd at 6V around the speed of ~15..20 km/h (...)

Hello, my car battery charger says its "4 Amp" ....it's a "BasicCharge4"
however, when i read the small print it says that its 4 Amps rms and 2.7A DC.
Why are they stating the rms current ?
surely its just the DC that matters ?

I think the voltage is 12v, right? What is the current rating of your battery? That will determine the charging current required, in turn the charging power and so the circuit topology.

Assuming a car amplifier with an IC designed for car use, then you dont need a lot of thinks.
