It's like Ray said....if your into serious competition stock racing dead short them.........In my experience the bennifits are noticable....more voltage,cells with lower internal resistance, more punch....battery packs that hold their match longer with only a slight reduction in runtime.....mine have only lost 15 to 30 seconds of runtime over the last 8 months and still have no problem dumping even with 10 and 12 turn kryptons........for maximum safety get every cell at dead zero (confirmed with a voltmeter) NEVER trust the lights on whatever trey you have)and its also a good idea to leave them on the trey while you solder the wire between pos and neg because the voltage rebounds pretty quick...not having the cells at zero when you do this is the (only) way they can generate heat and vent....for me ,the only downside to this procedure is the hour and a half to two hours it takes my trey to get the cells to go from .9 volts to zero
