It takes a couple of hours to bring a 10S pack down to storage level, and the charger gets pretty warm(!) during the discharge. Up to now I have only worried about discharging the pack for long term storage.</div><div style="font-family: 'times new roman', 'new york', times, serif; font-size: 12pt;"><br></div><div>If leaving the cells fully charged for more than a day or so is bad, I am considering building a dedicated discharger, there are some pretty simple yet effective designs on RCU.</div><div style="font-family: 'times new roman', 'new york', times, serif; font-size: 12pt;"> </div><div style="font-family: 'times new roman', 'new york', times, serif; font-size: 12pt;">Bob
