As you know, many/most transceivers want a 13.8 V input – charging voltage of a standard NiMH battery. This does not really match the modern world of LiIon/LiPo chemistry, on which a single cell can have between 3.3 to 4.2V – meaning an 3S pack would be 9.9 to 12.6V (too low) and an 4S…(Continue Reading)
