The unit meets exactly the requirements that one has to such a single slot-loader, even more so, the opportunity to make the _tatsächliche_ capacity newly purchased battery packs to determine and avoid it so, to operate different strong batteries in a team, is a real "added value": Otherwise, namely make the stronger battery dead the weaker sooner or later, and then you have to buy more which again. With the BC 700 it is therefore possible at this level still save money, not to mention the protection of the environment throughout. Weak point is that unfortunately some practice requiring operation, especially the fact that the onset of a new battery when this makes any errors, can also affect the settings of the already active neighboring bays. Somehow there seems to have 1 slot priority over the other, or vice versa? Really understood anyway, I'm not that. But maybe that is still ;-). Still, a purchase that I have regretted a moment and to whom I would also advise each other.
