Mark, have to disagree with you on this. I have soldered up many nimh packs. These are flight batteries powering the motor/rx on electric
planes. I have had drains up to 30 amps and more on these packs without nary a problemo. I've also soldered up 4 cell 1600 mah nimh batts for rx use in my glow planes. Never had a failure. For what ya pay for a futaba transmitter pack, I can make 3 nimh packs that last 3 times longer at the same voltage.
