I need somoene to design a pcb that will take power from a 12v 5amp DC adapter and will have 2pc 18650 lithium [login to view URL] batteries will be parallel connection . The batteries will be charged via the the dc source but will switch automatically to battery on power failure. The out put power will be be constant and linear 5v 2amp and 4v 2amp. I will have separate overcahrge and discharge protection circuiut for the batteries. These are meant to power up arduino with a number of microchips and gsp modules with gprs.
