GPS is correct, but I would prefer if you connected the sensors like this:
(just move all 3 connections 1 place)
A0 = Battery voltage (from resistor divider)
A1 = RSSI
A2 = Current sensor
It can be changed in software, but that's what I'll be using as default.
Please be aware that the voltage you have connected from the current-sensor MUST be connected with a voltage-divider. Otherwise you will end up with a dead Arduino.
(Vin is battery-voltage, Vout goes to A0 pin on Arduino. For max 4S li-po, with good safety margin, something like R1= 10K ohm and R2 = 3.3 K ohm could be a possibility)
