I've got a couple questions about storage charging. I bought a Hitec x2 AC plus battery charger for my Q500 batteries. In storage mode do you use a balance adapter during charging? The manual says it doesn't need to be connected to one but can be if preferred. Second question is when the charger says the battery is charged at the level you set at, you then shut it off. How long does a battery stay at the storage level before it starts to discharge from sitting before you need to restorage charge again? One month or longer or less? Before buying this charger I thought it would be like a battery trickler charge that always stayed hooked up to battery and came on by itself when needed. But I guess I thought wrong.
