Hello!
I want to make a circuit where by when the 5v dc source is switched on it charges the 4 X 18650 li-ion batteries in parallel. The total internal resistance of the 4 batteries in parallel is 0.025Ohm and the batteries are pcb protected.
And also while at it, it powers my load (a pocket router) rated at 5V, 1A input.
The maximum my 5V source can produce is 2A.
Here's the part where I just could figure out how to make it. How do I make it so that when the 5V source is present. The load (pocket router) is powered by the source and when the 5V source is switched off, it discharges from the batteries.

Any help is appreciated! Thanks in advance
