cool I was going to post a thread just like this as some of my 4200's are dieing so I can use my ripmax elite competition charger ?
the instructions say a charge current of 0.1 to 8A on li-po charge current but they also say 1C limited and as 7.4 v lipos are 2 cell this is a bit of a worry as the blurb in the manual mentions nothing else about the 1 cell limit.
I suspect I will pobably get 2 lipos of the saddle pack style and a balancer as they seem to be on ebay already

safe ebay linky.
I just hope lipo become legal as the amount of mucking about with cells I do seems never ending
