Hi-would anyone have a few 4S batteries for sale new or used?. I bought a Weekender from Towers and it flies on a 4S. Thanks,Alan.

Alan, I have a 2200 mAh Nanotech 35-70C, bought last June, used about 4-5 times. Internal resistance on each cell measured today at 005 mOhm which is excellent.

My charger do not show internal resistance. Any other way that I am not aware to measure it?

a simple wattmeter can do the job with some "math's"...

U=RxI
Volts = Ohms x Amps
The volts are : the drop voltage when loaded
Amps : the current with the load.
