Charge current is increased to 7A and the custom LCD now includes a blue backlight for easy viewing. T2 can handle LiPo packs with up to 5 cells in series. The input cord has installed banana plugs and large attachable alligator clips are included. The modified programming dial is easier to control. And a slight programming change, plus a totally new instruction manual for ease of use and understanding.
