I have a charger that connects to my PC and I can monitor and graph parameters in real time for each cell in a balanced pack, from internal resistance, to current, voltage wattage under various loads for each cell. For an unbalanced pack it shows the total values. You would be surprised how bad some packs are and how they age. I've all but done away with NiMH packs in particular. Sometimes you get a battery from a bad batch too, been there.
