I leave for 2 months in 15.5 hours. I have a Luna Shark 52v, 13.5ah battey pack. The pack was fully charged after I received it. It has had roughly 20 minutes of total use since mid January. I have the good charger... will charge to 80% if I chose... but reportedly will not discharge a battery. Luna said I should drain the battery to 50% charge for storage, but I have no time to do this by riding the trike (in storage). My guess is the battery is around 90% charged currently. Neither the trike nor the battery will accompany me. Anyone have any good reccomendations for the best thing I can do with my battery before I leave?
