hi guys,
It's been awhile since I've been around. Things change and life gets busy. I'm finally getting some time to get back to flying. I've only flown a couple of my smaller helis in the last year. Finally time to get serious. I've got a couple flights in this week, good to get back in the 'pilot's seat'.
I've got a question or two regarding lipos. I've had them with a storage charge for more than a year. They all came out of hibernation quite well except for one 6s 5000 mah. It still looks perfect but It's at least 4-5 years old and had many charges on it. 5 of the cells still have a good charge on them but #3 cell shows 0.0v (absolutely no voltage). I can't see any broken wire on the balancing lead. My questions are this:
I'm sure it's done but is there any other checks I can do to confirm it's toast? (It is a $140+ battery)
What's the best way to discharge what's left in the pack?
