My cheap Yuntong Smart Balancer from HobbyKing.com (luv ‘em!) arrived a couple of weeks ago, I’ve been using it a lot, and I’m happy to say that it actually seems to work. The ability to balance “offline” (while not charging) is surprisingly useful, because I can balance my LiPos while my charger is busy doing other (NiMH related) things. $19? Crazy price. I sometimes wonder if HobbyKing is too good to last.
