Connecting batteries in parallel is not a good idea.
They will begin to discharge each other.


I agree with that. Plus, if that guy plans on using the IC-735
transmitter at anywhere near its full power capability, even 2 4.5AH
batteries paralleled would be insufficient current capability. I don't
understand why someone would want to go to such lengths to use a bunch of
NiCd cells when the cost of a small automotive or motorcycle 12V lead acid
battery isn't that much, and would work much better.

This responce is to both Bob and Ed...

Actually my plan is to parallel at least 2, if not more, of these nicad
batteries together...

With your comments I think I may start out at 10 cells....

Thank you, muchly, for your input....appreciated...

Even that won't last too long. Myself, I wouldn't bother with those
small batteries unless you only plan to be on for a short time. Even
if you used 10 of the 7 amp/hr batteries, thats only 70 amp/hrs. Not
really too much for a 100w out HF rig. You have to worry about the
voltage drop/stability also, which BTW , Icoms are picky about.. Might
run the smaller 2m radio ok though..I use lead acid batteries for 100w
HF rigs. Preferably deep cycle, but a car battery will do fine as long
as you don't let it discharge too much to damage it. I run my ic-706
on a car battery and automatic charger here in the house.
