Hello everybody,
I have an old huawei r215 4g router with the battery almost dead, the original battery has three pins (you can see it here and here ), I found on youtube a tutorial how to build a "fake battery" with a capacitor and two resistors (here DIY Simple Dummy Baterai (Fake Baterai) | DIY. - YouTube ), but I'd like to use a 18650 battery: it has the same voltage, but i cannot understand how to connect it to the central pin, which I think should control battery status, using a resistor as shown in the tutorial could work? can anyone help me?
Thanks a lot
