I have 2 orion lipo's and one trackpower, I use them in my touring car,buggy and in my starter box for my 1/8th scale.Probably the best money i have spent on anything for my rc's in a couple of years. The bit i like the most with them is they don't discharge when not used for a week or two.The sooner we are able to race in all brca classes with lipo's the better
