I will start by saying that these batteries are great for the price. I have 4 or 5 five of these batteries. I bought a few the day after Thanksgiving last year for $20. I use them in my race trucks because I couldn't see paying a $100 bucks for one. They have worked well and seem to have good power and reserve but I have noticed they are starting to loose some of their juice. I probably have over 50 cycles over the ones I use the most (I marked them when new) and it just seemed that at the last race I was missing some speed about 2 minutes into the race. For someone just starting to race or getting into the hobby, I feel that these are the best batteries that money can buy. NEW info I have since purchased some of the Protek 100C batteries and there is definitely a difference in performance. I still recommend though for someone getting into the sport or hobby to buy the Ecopower batteries first. Until you understand the whole concept of charging and discharging LIPO batteries properly I would not buy expensive batteries just in case you damage a battery. Plus I wouldn't have been able to tell the difference between the Ecopower and Protek batteries when I first started racing because I could not consistently hold the truck straight and get on the throttle hard.
