1. I see there is two options for power; PWM and DC-DC. I would like to know the difference between the two and which is better?
2. I notice sometimes the LED screen doesn’t fully shut off, it goes into dim mode. Is this going to cause my battery to drain faster and if so how do I make it so it does not go dim and just always shuts off completely?
4. Last question, the store I bought it from said that you can connect it to a computer to download a new firmware if the come out with a new one. Is this true? If so how do I do that?
