I beg the differ,i use the reedy 20c with 30c burst and it has not swelled up after running it for about 2 months now.i run the jammin scrt-10 with a mamba max pro esc and the ballistic 550 4.5t and it only runs about 125 After 20 minutes of running,i also run the turnigy 2s 5000mah hardcase 20c-30c and works great.The novak ballistic 550 4.5t is a great motor ,gives great torque and great smooth power(sensored is the smoothest)Now it runs better on a 40c 2s 5000mah and would recommend it but your battery will work fine.
