John,
I enjoy reading your posts because they are always very informative and helpful even though I don't run the JRX-S any longer. However, I have to disagree with you on the Ice charger. I use mine to charge LiPo's and the amp rate is fully adjustable up to 8 amps. I use a 6000 Maxamps 2s2p pack. When first put into LiPo mode and you select the number of cells, it has a charge rate selected. All you have to do is scroll down to the charge amps and push in on the dial. I charge this battery at 1C as well as my transmitter LiPo. At least on my unit, the amperage is adjustable through the full range available on the charger, from .1 to 8.0 amps on any type of cell.
I really think you should reconsider the Ice as it is an excellent LiPo/LiMn charger.
