Mysterious Trace in Battery Fuel Gauge Datasheet
The BAT pin should not be shorted to the SRX pin. The SRX pin goes to the system VSYS and the charging source. The charging source cannot be a raw USB+5v, that will kill the LiPo, it needs to be the +ve output of a LiPo charger. The BAT pin goes to the battery pack. 

Figure 9 on page 20 is not meant to be a 'layout', it is a hybrid abomination which shows the footprint of the device, and a schematic of its connections. Unfortunately, the data sheet shows evidence of having been cobbled together hastily from a previous gas-gauge IC that used an external resistor. Section 10.2.2.3 discusses the selection of a suitable resistor. The tracking under the IC on figure 9 appears to show a trace between the BAT and SRX pins, which could be an alternative implementation of this resistor. This should not be there, and is obviously a hangover from the previous data sheet.

The resistance inside the chip between SRX and BAT is typically 7m\$\Omega\$ which produces a voltage for the ADC to digitise when battery current flows in or out. You do not add any extra resistance externally between these pins, or you will upset the calibration.
