I have designed a two stage battery Charger using 555 timer IC in Schimit mode. I would Like you to review it and make some suggestions if necessary.
This Circuit Switches on the Relay Whenever the Supply Voltage is Less than 12.6 Volts (set by VR2) and switches of the Relay whenever the supply voltage is greater than 14.8 Volts (set by VR1). The Relay Swithces between two chargers, one of High Amperes and Other of Low Amperes.
