This looks like a real nice charger as it does about everything! Is there a US version?

One for all – the new power charger cannot only charge all commercially available battery systems simultaneously, including LiPo batteries, it does very fast on four independent charging channels and operates in a way which protects the batteries. A newly developed microprocessor-controlled battery management saves battery data individually, compiles it in a database and transfers to a PC via a USB port. The data can be evaluated in detail with the optional “Charge Professional” PC software. You always know the state of all your batteries. If something new comes onto the battery market – no problem! Thanks to the Flash memory technology, the charging device can fulfill future needs!

Well interesting but what about balancing?
Would be nice if it supported a balancer with data about each cell and how far out they were, etc.

I strongly agree with Bob. Balancing is the most important feature
of a charger, as well as software that logs data about individual cells.
I would hate to buy a new charger that requires the use of an external
balancer.

Nice videos Finless :noteworthy
