Hello,  
I am still very new to the Raspberry/Maker world - forgive if this is a stupid question. I intend to build a robot driven by a Raspberry Pi Zero W and use the SparkFun Servo pHAT as interface to the motors/servos. As it should be a proper robot, I need to use some batteries as power supply and intend to connect a power bank to the USB-C socket on the pHAT.  
Is there any functionality to monitor the battery level to avoid crashing the system when it runs out? I found a module “PiJuice Zero” (sorry, different supplier), but it also sits on the GPIO pins. Can those two get stacked or what other ideas would anyone have?  
Thanks so much, Stemmi
