"C" stands for capacity and the "C rating" is the maximum safe continuous discharge rate of a pack. If you see 65C on your battery, it means the manufacturer has tested a safe discharge rate at 65 times that pack's capacity.

Higher C rating typically coincides with less resistance which means less heat which means longer battery life.

Less resistance also means faster charge times.

All C ratings aren't the same. Some manufacturers rate their cells conservatively and some over rate their cells.

But I would stick to 35C or better from a well known source, you'll get newer tech cells with relatively low resistance.

Warranty and crash replacement is always a plus.
