Congrats on your new lipo 4s battery set up. You did it right and you did your research. The only thing I would suggest is to add a battery monitor 4s. ( picture below) Wire it parallel to circuit.
If the battery goes below 3volts from the battery factory rate the monitor will beep. This is better than watching your FF screen all the time. And yes keep an eye on your cells with a cell monitor as well.
You should be good all day and more with only one 14'8 4s battery. I wanted something that would last me for two days so got the 6500mAh Lipo Batt.
