basically you have to time it to be beneficial.
know how long it take to discharge at 40 amp and charge at 20 amps( or more)
and time it right before your heat/main. (i don't do this cause i cant afford new lipos every 3 to 6 months).
heat in lipo is what reduces the ir but most have rules where you cant heat the outside so u have to do it internally.
This is done alot in one cell stock racing. High discharge creates heat in the battery which reduces IR and gives a little extra spunk up front but, as stated, if this isn't done back to back just before your next race, it's all for nothing. If the battery sits a few minutes after this disch/chg cycle before the race starts, nothing gained. I don't think this would be worth the hassle for 2S and up.
