welcome to wattflyer jimmy, if you have a discharge mode on your charger the answer is yes...they do help.
what charger are you using? i use the cellpro powerlab6 and discharge 6 batteries at the same time[must be same cell count]. this is the first time i ever used this type of charger to get storage voltage/balance after using packs or lowering volts on packs fully charged but not flown. todays flights have me still needing to balance 15 packs. 9 of them will be put away safe in storage level,the 6 smaller 3cell 1000mah i use on a superfly delta epp wing will sit fully charged in a metal storage box as i fly during the week at local school fields and always want to be ready at a moments desire to fly
