703S is under development, so stay tuned

Is anyone aware of what type of battery this takes?

It has a built in rechargeable 18650 battery.

Can this unit charge from a USB-C to USB-C cable? Or does it need to be a USB-A to USB-C cable?

The meter has a USB C connection on the body, just like a modern cellphone, so that end of the cable must be USB C. The other end can be whatever you like, A, or C, or even B. In my case I just used my cellphone charger, which has USB C on both sides.

How show the wave line bigger? It just showes a small straight line and the arrows does not changes a lot

Not sure of your question, but let me go over these items. I assume when you say a line, that you are in the oscilloscope mode of the meter. The input to the oscilloscope mode is a probe that plugs into the top of the meter. (Meter mode uses the other two probes that plug into the bottom front of the meter.) With no signal the line is a trace of a single point moving according to the time base. If you input a clean signal then the signal wave will be a single point trace. The trace may be showing noise or harmonics on top of the signal making the trace look wider.
