Clean electricity generation paired with the first grid-level sodium battery energy storage system can bring costs down to just $0.028 per kWh. The 10 MWh storage capacity is executed with sodium-ion cells that can be charged in just 12 minutes.
The C rating is generally what battery charging (and discharging) is measured in. C being the capacity of the pack. So if the pack is 10 Ah and it takes 10 hours to charge it’s 1c, if it takes 1 hour to charge then it’s 10c.

I found this high current battery pack that’s rated for 30c. https://www.lipobattery.us/high-discharge-lithium-ion-battery-30c-2/
I don’t feel like doing the math for this battery pack.
The C rating is for discharging only.
The C rating can absolutely still be used when talking about recharging, it’s just usually less relevant.
No. The C rating is a cell’s maximum discharge rate without damaging the cell.
You absolutely can’t charge that 30C battery at 30A
Batteries have separate C ratings for charge and discharge.
You are not completely right. 1 C means it can (theoretically) be charged in 1h. Regardless of the capacity.
10 C means it can be charged in 1/10th of an hour.
To get the maximum current, multiply the capacity by the C rating.
