A reader recently requested I elaborate on the comms equipment battery charging system I carry in my Ruck.
First let me say that the setup I use is not what I would prefer but it works. I would prefer an ultra light weight system that I could attach directly to my Elecraft KX3 and charge the batteries using its built-in battery charger. The radios built in charger requires 13.8 volts dc but I haven’t found a pack-able panel that supplies that voltage. Most backpack/camping panels supply 5 vdc. That would require 3 sets of panels connected in series to get the necessary voltage. So, what I’ve had to resort to is removing the batteries from whatever radio I’m using, and charging the batteries in a charger that’s connected to the solar panels.
My current setup consists of the XTAR VC4 Charger and the Renogy Solar 14 watt E-Flex Solar Power Panel with dual USB ports.
