Hi all,
I bought a telescope that requires 12V 1500mA power supply. I would like to make a battery pack that powers it up without the need of external power supply. Even it comes with car battery cable I would like to make my power tank using Lithium batteries because they are light in weight and I have to place battery pack on the rotating shelf without worrying about the cord being tangled when telescope moves.
I would like to connect 4S (14.8V) battery, what I can do to regulate the output to 12V? If I use LM7812 it only allows 1A max. Please suggest some simple circuit so that I can power my telescope. Also, I have a very good charger for LiPos so I don't have to worry about charging the pack.
Thanks all
