Greetings

I am in the process of putting together (battery power supply) for my
amateur radio equipment....I have an ic 735 and ic 275a.

I have a number of rechargable nicad batteries 4.400 amp hour and 7.0 amp
hour.. 1.25 volts..

I need some information about the ic equipment which I can't seem to find in
the manual...
In the manual the d.c. input reads 12 volts...

Can someone tell me what the safe upper limit of these radios tend to be?

I don't plan to come anywhere need the upper limit but I would perfer to
make a battery pack containing 12 x 1.25 volt cells rather than 11 cells.

My battery analyzer, cadex 7000, can only analyzer a series string of 1 to
12 cells.

My Icom 735 manual specifies the power supply requirements: 13.8V DC,
plus or minus 15%, negative ground.

At 200 watts input, it pulls about 20 amps. Receiving, about 1.5 amps,
or 1.2 amps, squelched.

Later in the manual, it says for battery power, you can go with 12 to
15 volts.

It also mentions that anything over 15 volts may damage the rig.
