Minimum Battery Specs?
 

What is the Minimum Battery spec I need for a 4s Brushless conversion using a Medusa 2200 60mm can battery?

At the moment I have Reedy 5000's 20C which seem fine, but I can get some 4600's 20C, or is that too low?

What should I be chasing?

Really need the whole setup to really know, but so long as you got at least 90 amp continous you should be good. I have run 3700 mah 20c LIPO's on my MT with no problems, I have a G2R with neu 1515/2.5d w/quark 125, It has been run on 4,5 and 6s setups with those batteries

i used to run my 8ight on a v2 2200-60mm medusa on 4s 5000 zippy's rated 20-30C and neuenergy lipos 4s 5000mah rated at 20C....the same motor and setup worked fine in my e-maxx as well...
