I always just leave my packs as they come out of the car, then discharge and equalise them just before charging them to use (on the day jimmy
).
Don't use a discharge board that dead shorts them, don't cycle packs unnecessarily as you get few enough useful cycles from some cell types, don't charge above 5.5 amps, don't peak them up as they have lots of punch anyway and peaking just heats them up before your run. Try to put them in your car stone cold, Orion advantage with step charging is awesome for this, they peak off ready for your run and are just warm to the touch, no more.
