Hi Everyone
I am a new H user and have bought 3 batteries from China. I have seen and read some posts regarding Internal Resistance (IR) and understand that this changes with temperature, charge and that they should all be low values and closely matched for a good battery etc.
I took the IR when i received them yesterday (uncharged / storage charge) and again 30 minutes after the 1st balance charg today. All values are milliohm's. I am using a Reaktor Quadcore charger bought from HobbyKing a few years ago.
My question is - As the new battery cells IR are not all closely matched to each other - should i return them as defective or am i worrying to much about them?
The IR results are posted below:
Battery 1 - Cell 1 (new = 9, charged = 6), Cell 2 (new = 8, charged = 5), Cell 3 (new = 13, charged = 10), Cell 4 (new = 11, charged = 10)
Battery 2 - Cell 1 (new = 10, charged =7), Cell 2 (new = 9, charged = 6), Cell 3 (new = 12, charged = 12), Cell 4 (new = 13, charged = 11)
Battery 3 - Cell 1 (new = 10, charged =7), Cell 2 (new = 8, charged = 5), Cell 3 (new = 14, charged = 11), Cell 4 (new = 13, charged = 10)
