I have 2 of the 0610is and use them to network charge 5S and 6S1P a123 pacs as wellas all my other lipos and a few NiMh pacs. I added the 2nd after the price went down and thinkfor my situation, made the right choice. I considered selling the one and getting a DUO, but decided to network charge instead - DUO is limited to 180watts per side. I charge my a123s at 10a, so for the 6S, thats 216watts, hardest I've pushed so far.

The last update, v2, added a new feature in user setup that allows you to chose 1C thru 5C as an available lipo charge rate. Hyperions supposed to have released lipos already that charge at those higher C rates. It was good to see Hyperion continue to support the 0610i - have been 2 firmware upgrades since the 0720 hit the shelves. I think they are still making them or there is still some in the pipeline, anyone thats run out has gotten more back in stock.
