My old Venom Pro charger used to discharge batteries down to 3.8V/cell when storage was selected. I've got some 4S lipos that I didn't get to use on the weekend and wont be using them for a fortnight.
When I put them on my new Team Orion Advantage Race Spec for storage it says "storage complete" even though they are still 4.2V/cell. Is it ok for them to be stored at such voltage? I would have thought if they needed to be discharged to ~3.8V that a charger of this quality would have it built in, so it makes me wonder if it's necessary...
