When this power supply model is applied to an external circuit, then the circuit current also flows through the internal resistance. ... is equal to the open circuit terminal voltage of the power ...
Get PriceI have an idea to make a mod that supports both an internal battery and DC power in socket. You have these DC sockets that have a physical switch which disconnects the internal power source when you insert a plug. Pretty easy but the problem is that you can only switch between Battery power and Power Supply through escribe.
Get PriceThe power supply has an emf (E) and internal resistance (r). An external resistor (R) (also called a load) is connected in series. ..., where R is the external circuit resistance and I is the current in the supply. A battery delivers maximum power to a circuit when the load resistance is equal to the internal resistance of the battery.

Get PriceI use both a regulated external power supply and/or a 12.8 LiFePO4 battery. The radio does not fall back to 5W. However, I have not done the testing to see at what volatage it might drop back to 5 watts. Since the internal battery voltage is around 8.2V which gives 5 watts, I suspect it will require between 10v and above to achieve 10 …

Get PricePortable equipment that can operate from a battery pack or an external power source (such as a wall-adapter or external supply) needs to be able to smoothly switch between the two power sources. This application note describes a circuit (Figure 1) that switches power sources with good efficiency and without switching noise. Figure 1.
Get PriceActually, 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.
