checked my #lipo #batteries and like 50% of my tiny 250-450mAh 1S ones mutated into #spicyPillows :-(
i guess that was bad storage on my part
@cegorach oh no! That sucks
@cegorach That sucks. Were they stored at full voltage?
@doachs
nah, perfect storage charge when I stored them
but left alone a bit too long (had no time for like the last two years to fly - should have checked the batteries at least) and way too warm during the last 2 months
