I just unboxed a new Nitecore SC4 battery charger. Was very excited to have the ability to charge at 6amps across four slots AND to be able to measure the battery's internal resistance.
So, after measuring the internal resistance of twenty 18650s and six 26650s, I realized the resistance measured by the charger would almost always be different if I remeasured the battery.
When measuring the battery, I only insert it long enough to take a reading not to begin charging and therefore heating the battery which could affect the resistance.
Does anyone else have this charger? If so, what are your results when measuring the IR?
