Surely this is what "matchers" do, charge-rest-discharge-rest-charge -rest-discharge.......check & compare discharge figures. Rest allows cooling.
Personaly we charge the day before racing and store half charged, thats how 5 minutes of racing leaves em, ocasionaly I will discharge & equalise, then half charge and store, mainly because I think I ought to equalise, and have a cheap tray, but not convinced its worth the effort, its almost the Jimmy method.
