[NSRCA-discussion] NiMH Question

[Bob Richards]

The diodes they used back then probably would not work as well in a modern system, since we have much more of a current drain with today's servos.
   
  I would suspect any good rectifier rated for the expected current would work.

  Some of the old radios (Proline, for instance) had diodes across each cell in the airborne pack, in case a cell went open. Also, if a cell died (lost voltage) it would minimize the problem by preventing a cell from reverse charging.
