Sparkfun LiPo Fuel Gauge - wiring

I bought two of these: LiPo Fuel Gauges.

Mine always reads 256% charge and 5 Volts. I’m guessing that I’ve hooked it up wrong.

There are + and - pins; and there are also VCC and GND pins. Do I hook the LiPo to + and -? Then do I run my load from VCC and GND?

Basically I’m looking for a hookup diagram. I’ve seen conflicting videos re: hookup. Thanks for any help.

Note: I got eBay clones, so that may well be the problem - I've ordered two more from Sparkfun. I'll post here when they come in.
