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 system from the ceiling. Each of these devices use 12VDC.
Here is my question: Would it be possible to use a car battery charger hooked up to a car battery, and then hook up the devices to the battery so that the battery will work as a safety in case the power goes out? I do not want to get locked out of my house in case of a power failure. If so, what would the circuit look like? Can I just set everything up in a parallel arrangement? I would like to have the devices feed off the battery and the charger to charge the battery as it needs to without any intervention.
Thanks very much for any help you can offer me and sorry for the noob questions; I'm not really skilled with electronics but they really fascinate me.
