4s 8000mah only 5c
 

thats only 4o amps, i want to run a 1515 2200kv neu, will i have problems with only 5c?

I assume your talking about an MT or 1/8th, but no 40 amps won't be enough for decent power with 4s. I'd aim for 100amps or at least 80.
How come you didn't just edit the other thread?

Ha! I thought it was two different battery types. I didn't realize the 40 amp drain rate battery was only 5c. It all comes down to you get what you pay for. Cheap batteries are, well, cheap. But thanks for the help and knowledge everybody, I always learn when I log on. If only I had this much interest in school!
