What''s a simpler way to switch between power sources?
The highest performance (most power efficient/coolest) method is to use a FET OR-ing setup. Their primary advantage is a near-zero voltage drop, limited only by the R DS(on) of the FET and current sense resistor (10 mΩ total resistance is fairly easy, but 1-2 mΩ if you really need).. Controllers for said systems typically use a low-value sense …

What external battery do I pair with the Icom IC-705?
Actually, Brad, the IC-705 wants 12 VDC +/- 15% to run a full 10 watts. 16 volts is *way* over the amount the IC-705 can handle and could very well damage it if overvoltage protection doesn''t kick in. All of the Bioenno packs I mention are 12 volts, so ideal for the IC-705 and most of the portable transceivers on the market today.
