For anyone reading this and still wondering, I found the answer by searching "lipo C rating explained".
Here it is:
Say you have a 10 AH cell. It can provide 10 amps for an hour, or 1 amp for 10 hours, or 2 amps for 5 hrs, etc.
Say the 10 AH cell is rated at 1C. That means you can charge it (or discharge it) at 10 amps. If it's rated 2C, you can charge/discharge it at 2x that rate, or 20 amps. If rated 5C you can charge/discharge it at 5x that rate, or 50 amps. Exceed that rating and you'll overheat it or damage it some other way.
There's usually a second, higher rate also posted. That's a higher charge/discharge rate that can only be maintained briefly. The spec should state how long it can discharge safely at the higher rate.
