I am trying to make a charging circuit to charge 2 NiMH batteries via trickle charging with 0.015A (15mA)
I have used a current regulator and basically J1 is connected to the source of 24V DC and J2 are the 2x9V NiMH batteries in series that are going to be charged.
I'm unsure where to connect the '2' from the J2 as previously I just connected to ground. Is ground just the same thing as the negative terminal on a battery?
But the '1' from J1 has to connect somewhere right?
