Sky rs16 does not work using the balance port, as you say i use the icharger, though many other chargers do allow the balance port to be uused on 1s mode, as matt says the balance leads need to be to the balance port and the battery main terminals at the battery end.

Thats not my lead but a generic picture.(2s lead will not work as the pins on the blance lead are wrong, needs to be wired as picture in op)


Principles are

It gives a safer charge, far less chance of end user sellecting wrong cell count.

It gives a more accurate charge, where the main leads are carrying amps to charge the cell, voltage losses can result in the internal charger voltage readings being out, using the balance function is efectivly sticking an external mutlimeter to monitor voltage.

My icharger on 1s regulary sees 4.3 volts on the main cable voltage, yet the balance port reading is 4.2, at scruteneering on thier claibrated meters its allways 4.2 and never over or under.

Many chargers do do this including the newer skyrc ones.
Its widley used in 1s racing, and if you think about it , its just how a 2s plus voltage is measured


Im sure some one will argue the case its aload of maloney, but as stated widley used in 1s racing and if it had no benifit manufactures would not add it as a feature to thier chargers)
