Hello,
I have a system powered form a 14.8V (nominal) battery; It's a LiOn and can be recharged by an appropriate battery charger with a 16.2V output. I want to have an external power source (DC 9V to 36V) that, when plugged in, power my system and also disconnect the battery (and obviously the charger). Upon external power disconnection the system must return to the battery source. The system load is around 6A, but I would to like to support up to 10A. Someone can suggest a nice MOSFET based circuit avoiding use of mechanical relays.
