I just purchased 3 and have purchased 5 or more over the past few years. Theses batteries are awsome, especially perfect for fdl3, fdl basic, and many other blasters I own. The size is quite perfect and performance is excellent as well. There's plenty of power and the battery last a long time as well(charge wise). Also ineven have the batteries I bought years ago still work, great quality. Take care of this battery and it will take care of you.
This battery is a BEAST. It will rev a pair of Krakens with Daybreak wheels (these are really heavy at over 7 grams and a really long polar moment at nearly 37mm) from full stop to max rpm in about 1/4 second. It will rev 2 pairs of Fang RVs (over volting to 3S) to stratospheric rpm in about 1/2 second while powering an overvolted pusher motor to 16 rounds/second. I'm buying a second one! Luke, could you see about sourcing a similarly monstrous 2S version?
