yeah, that's true unless there is like 3.7v in each cell, then he would be reading 3.7, 7.4 and 11.1, but that last reading wouldn't match up... =P hrm, you do make a good point arrow

on the balance end if you number the contacts 1 2 3 4, measure 1 and 2 record that voltage, measure 2 and 3 and record that voltage and then finally 3 and 4.... all of them should be the same and between 4.1 and 4.2v

35 min to charge sounds really suspect. You might also look at your main and or tail motor and see how hot they are getting because they might need replacing. Also your battery could be toast if you have run it below 3.0v under a load one or more times. I find a good battery meter makes alot of difference that way. I use this one

but there are several out there.
