Going back to Flux. Fill me in on Lipo & chargers

[Finnster]

I wouldn't leave any lipos fully charged for "long periods" of time as its not good for the chemistry long term. How long you are talking about? A couple weeks is fine IMO, but more than that I would store at 50%. A decent charger will have a storage program, so it really shouldn't be an issue to store, then charge up the night before (or two) before you plan to take the truck out. A 12hr window is stupid BS and a sure sign of a scam.
