charging 10 cell nimh pack 6 cells at a time?
I need to charge a 10 cell nimh pack, but my input voltage is only
12VDC. I dont want to use a switching power supply.
I'm thinking that if I charge the 10 cells in two banks, i.e., 5 at a
time, and I switch between the banks very quickly (100 times per
second say), that I will be able to charge the entire 10 cells okay.
And since I am switching between the packs so quickly I could still
use dt/dt termination (change in temperature rise) since its a
relatively slow phenomenon and switching between packs is essentially
like using a pulsed-current charge method which is pretty standard.
Anyone ever do this? Comments?

The thing here is that as long as the packs are of the same chemistry/construction style and from the same manufacturer, *even if the cells are of differing capacity* you can connect two packs in parallel *once you are sure they are at an equal state of charge*. ...
