I charge mine in a pyrex pot, and put a lid on it... but I have sand and a small fire extinguisher handy just incase something was to happen...  |
Thats what I had read too - these were 2S cells that had between 75 and 100 cycles on them with one being brand new - hadn't even soldered the deans on yet. I was planning on being gone for 30-45 days and was gone almost 90days. Even the new one was puffed. The cell pro balancer had said all were in balance after I charged them to 50% of what they had used in their prev cycle. No one (2 diff brands) has been able to explain why this happened and I feel if I had left them fully charged, I'd still be using them. They were stored at 68F.
After losing 5 batts that way, I use mine every month no matter what, even if its only to disch/chrg on charger.
