Hello everyone,
This is my first post on this forum, and I am looking for people who could give me advise on my design!
The software is based on microchip's AN1015, and the circuit has been 'extensively' tested, apart from the 'anti reverse polarity' relay.
I'd like to know if I am doing something horribly wrong and/or should make some smaller changes. Minding, when this project is 100%, I'd like to make several of these, so want to keep the components as cheap and the disign as simple as possible!
Also I have few questions:
PS: Do not mind the max. voltage of 15.6V stated in the circuit2.jpg, that was intended for a future 'battery equalizing' stage which is not even implemented into the software yet. For now ATX =max. 15.07V and the battery =max. 14.70V.
Thanks in advance.

Also I have few questions:
- Would I be able to draw 15 amps from the modified ATX(normally 12V/16A) regulated at 14.7V ?
- I am assuming the wire-wound shunt resistors need a fly-back diode. What is the right diode for this(now using SF16 and/or for the relay?
- Can I be A 100% sure a 12V relay will work with an empty battery of +/-11V ?
- Would there be a better(cheap) solution to reduce the voltage on the fan M1, from 13.6/14.7 to +/-12V ?
