Didn't see a battery section Tony so the charger section seemed like the next best spot.
Question number 1: How do you measure the voltage of individual cells? Whenever I put a multimeter on the first and second pins of the balance plug I get a number that looks like 1 cell voltage, i.e. 3.7, but when I put it on pins 1 and 3 I get a number like 2 cells i.e. 7.2 and so on. Do I just write down each value and subtract the first cell value from the second value and that is it, or am I doing it wrong somehow?
Question number 2: How damaging is it really to leave a lipo at full charge for extended periods of time, like a month or more? With my Thunder AC6 it takes a full evening to charge all my 3S lipos and with the wind in Oklahoma I never know when I might actually get a chance to fly. If I don't leave them charged I stand a good chance of missing a nice flying day.
Question number 3: Are there any good sub $100 charger/powersupply combos that will show internal resistance? I have looked on my AC6 and it doesn't appear to do it.
