i have that charger and it is great except for mine has a problem with balancing my 4s lipo. it has no problems with any of my other 10 or so batteries, it just won't charge my 4s right. it can charge 10a @200W.
They say a good mechanic only needs 2 tools - WD40 & Duct tape. If it moves, and its not supposed to, duct tape. If it doesn't move, and its supposed to, WD40.
