I hate to say that, but El, those BC6 review are just reproduction of their manual to tell the features whereas Tim's review is a scientific testing of the IMAX B6, in addition to Tim's one, there is another scientific review about the IMAX B6, they probvide real life testing and I would say their data are from abuse testing of the charger. For me, as a novice flyer, the charger did provide safe, ease of use, fairly accruate and most important, stays within my budget. I use it to charge to packs in series at field and even I just take the lowest cell voltage as a reference point, I still have fun. BC6 has a problem of its own, a 50W charger for that price is a bit too much.
