70 amp charger cooking 12v LEDs?
Will using one of the upgraded 70amp Progressive Dynamics charger/converters fry my new 12v LEDs (unregulated version)? I've seen talk of leaving the old converter in place, deck mounting the new o...

I have a QRP ham radio that while listening pulls about 180 to 190 mAh. It runs at from 15.0 to 10.0V From 15 to 14V at about 3000 mah, it will transmit at 15w under voltage sag. From 14.0V to 12.0V, it will transmit at 10w. Under 12.0V, it will automatically drop down to 5w.
Since I do remote field operations, I've bought a 4S Li Poly battery that starts out at 16.8V, drops down and runs at 14.8V for a long time, then the V drops off and under 12.0v I will be at 5w.
I want a set of diodes in series that will handle 3 to 4 amps, with enough diodes in series that it will drop the V down from 16.8 to 15.3V or slightly less, as there is also a protection reverse current diode in the radio that drops input voltage another 0.3V. I want to be able to run at 15 watts as long as possible when doing activations while remote.
