Dummy battery Huawei e5577 e5573 mifi modem

How to make a dummy battery to run your pocket modem without constantly charging the original battery.

You can prevent your original battery from swelling or potentially causing a fire.

In my case I'm using a small 6v-24v to 5v 3a buck converter inside the battery compartment but you could also use the power from a USB charger.

The list of the components I used is:

1 diode 1N4004 400v 1a DO41

1 resistor 0.5w MTL 10K 1% mini

1 6v-24v to 5v 3a buck converter USB.
