Admiral Batteries vs. Turnigy

Since the measurement method of your charger is unknown, you can't compare your numbers to mine. And, yes, DeoxIT is a contact cleaner - a rather good one, IMO.

I got my Wayne Giles meter today and took some quick readings by the book on a 4s 3300mah, 60-120c heavy duty pack at 76° in the room and have this for each cell:
cell 1= 14c, Max I= 46.8a, 3.84v, 9.08ohms.
cell 2=14c, Max I=48.6a, 3.84v, 8.92ohms.
cell 3= 13c, Max I=45a, 3.83v, 9.76ohms.
cell 4= 15c, Max I=50.4a, 3.84v, 8.04ohms.

What do you think? Just a quick check by the book to record what the readings were. Happy Thanksgiving to you and yours and all the hobbysquack squackers!

The numbers are a lot more consistent than with the previous tests; a bit higher than I would have expected. If that is a new battery, you should test again after four of five flights, as many lipos will improve with a short break-in; I've had some improve by as much as a 20% drop in IR. Still, a steady 45A is pretty good, as that would be a 3.7 minute flight; surge current should be as much as 25% higher, without too much Voltage sag, so you should be able to fly a plane that peaks over 830W on a fast take-off or a brief vertical.
