The C rating can also be helpful when charging as well. As an example a pack with a capacity of 4300 mAh; a 1C charge rate would be 4.3 amps, 2C charge would be 8.6 amps, 3C charge would be 12.9 amps.......etc.
The only company that I can think of that has a really truthful C rated pack is ThunderPower, though I will say my big HK 6s packs have been holding pretty true to their 30c rating. I've noticed one of them has a cell that's starting to take a dump though :banghead:
Who would have ever thought there'd be so much info to learn about a hobby we do for fun LOL.
so as a clarifying question to an old thread. If I have a 3000mah 3s 20C, that would be rated for 6A correct? Is that the max safe draw for the battery? I assume that the battery would provide the full voltage and power for as long as it has any charge in it (think of a direct short). Would you notice a power difference to the motor running a 40C over a 20C battery pack? Also this may be a bit off topic but if I have a 6A pack (20C 3000) why will it run a 45A esc? I have a basic understanding of electricity just trying to clarify.
