So I am new to the hobby again in a whole new generation as my last RC car was 25 years ago and boring. So when I splurged on the Kraton at K & K hobby in FL a month ago they sold me Powerhobby batteries. Should I be using something else? Am I missing out on some power loss? Thanks from the newbie.Same here, after 40+ lipo's i only buy the Graphenes, they are worth it.
