    I want to cutoff the battery from load, while charging it. Schematic of the designed circuit is attached. I have used a PNP transistor to do it. Positive terminal of the battery is connected to emitter, charger positive input is connected to base. Simulation is running good but I want to know would this circuit work in hardware? Is there any problem with the circuit?

    It should work, but a FET might be more efficient.
