The 10s is awesome. I have had mine for a few weeks and its by far the most advanced charger I have seen. The computer interface and graphing battery logging capabilities are flat out beautiful. Everything you ever wanted to know about your battery and more. Internal resistance of the individual cells and everything and perfect balancing with no thought at all.

But be aware of a couple things. The price includes 2 wire sets for charging FMA batteries only. To charge packs with Hyperion and TP style balance plugs you need to buy their adapter. Its only $10 but to do 2 packs at once you need 2 of them. Also they don't include charge plugs for the main battery hook up. You will need 2 sets of banana plug to Deans(or whatever you use) wires also. And then the usb wire is also another $20 if you want to use the computer graphing and analysis capabilities.

So there are a few "extras" that you need to get the most out of the charger that IMO should just come with the charger. But even at that its still worth it IMO. the most advanced charger I have ever seen or used yet still very easy to use.

BTW... I have an Extrema as well and it too is a stellar unit. The lack of built in balancing is its only shortcoming IMO. They do have a balancing system that plugs into and directly interfaces with the Extrema so it works like a single unit, but If I remember it was pretty pricey. I just use it with the old LBA10 balancer with no troubles at all.
