sir
actualy i have now decided not to use that ckt, because practically this ckt is proven with resistive load of 15 amp 100v, but for this battery load where current is not predictable ,i have studied different options, after than i came to conclusion i will use mosfet driver ir 2110,or 2118, i will use current sensing resistor and keep the current in limit, i will use inrush current limiter, 555 pwm controlled signal ,and appropriate snubber ckt, i have found different ckts, now i am just optimising it
