*** Update 2 I just got an email from a second representative at efest, where they state that the 2000mah is 5C. Boggles my mind. 2000mah is back down to 10A.
***UPDATE I have recieved a reply from efest regarding the c-ratings of their IMR batteries, a topic which I know has been of debate on these forums. They clearly stated that the absolute lowest c-rating for any of their red IMR battery types is 8C. Unfortunately they did not comment specifically on the models I asked for info on. This means that the 2000 mah actually has an max discharge of at least 16A.
Continuing on from my post on battery safety, I have compiled a list of the accepted maximum amp discharge ratings for different battery types. This has been a work in progress for quite some time. Several emails had to be sent to manufacturers in order to obtain correct data.
It should be noted that where definitive data could not be obtained (due to Chinese new year) I have posted the lowest accepted maximum discharge rate for the battery. With more information I will endeavour to update this list as I get it.
*NOTE! This resistance number will put you at EXACTLY the maximum discharge rating for the battery when using a fully charged battery at 4.2 volts. It is NOT advisable that you toe this line, give yourself a margin for error and safety!
