Looking for 9.6v butterfly recommendations. Im using a matrix and a tenergy, the tenergy is noticeably better then the matrix. I’ve been told the tenergy isn’t the greatest battery so does anybody know of a battery better then a tenergy? I’ve seen the lancer and the venom batteries but I’m not sure which is better and if they will make a noticeable difference. Also sense we are on the topic. Is there a point in swapping out my connectors for deans?
