i'm building a robot (a sort of rover) which includes a 12V/7Ah SLA battery. The robot circuit needs a regulated 12V supply to work correctly.
I would like to charge my rover using a generic 14-19V DC power supply.
Now the question is, what device should I use to charge the battery when this is connected to the robot circuit and at the same time regulate the output to 12V?
I found the following device, but apparently this will work only if connected to solar panel. Other than this limitation it does exactly what I want to accomplish.
Could you suggest a on-the-shelf product for what i need, or otherwise if simple to create the circuit that I should build?
Thanks for your time :)
