"Red" Scholefield from the RC Battery Clinic (
http://www.rcbatteryclinic.com/ ) told me, via e-mail, that the recommended way to store lipo's is to charge or discharge them to 3.7 volts per cell. Red said this was the way the manufacturers keep their cells prior to building a pack.
I certainly don't want to dispute Mr. Scholefield' recommendations but if storage voltage is so important why have none of the multitude of lipo batteries I have owned mentioned this in any literature from the manufacturer and the only way this recommendation is even mentioned is from a 3rd party through an email or from rumors floating around.
Like I said I store mine fully charged and it works fine for me. I don't have any ancient lipo batteries but do have a couple that are several years old and still going strong.
