Best damn balance charger I ever had

Actually, wouldn't the fact that the battery has the same wire and connection on both sides of the circuit make the resistance the same in front and behind the charger making the voltage read lower and lower when the internal resistance of the charger goes closer to zero (aka a high rate of charge)? In a since it's making a voltage divider circuit.



In this case the outer 2 resistances are the connectors/wires and the middle is the charger. But in all honesty, I doubt the wires have enough resistance to really matter enough considering that Lipo batteries can actually go slightly over 4.2v per cell. They just cut it at 4.2 for safety and most chargers are programed to read a just slightly higher voltage than actual so in production, the resistor values put in it don't have to be super extreme tolerances to still be safe.

Just my two cents and theory from what little electrical engineering know how I have.
