So ive been out for a while and need some battery help for my revo

[jokerjustin]

Like i said ive been out of commision for a while.. after having my turnigy battery almost blow on me i havent had the finances to get another one... its been almost a year and i feel out of the loop
its a revo that i had set up for 4s and would like to keep it at 4s since thats the max my ice charger can handle. im looking to spend about 100 max on a battery.. are turnigys still the answer? i saw something about nano tech batteries?

currently have a mmm with the 2200kv motor
