Lipo battery fail......safe to reuse?
« on: October 12, 2017, 01:20:07 PM »

I just took my Perkasa for a sail. I am aware  of  the low voltage cut off and the esc is set and I have a bleeper fitted to sound before reaching the esc cut off. (However my deafness makes the bleeper hard to detect).
The boat just stopped and I had to recover it to find the battery was extremely low and a little puffy.
I am unsure if I missed the bleeper sounding but even so the esc should then have kicked in and when this happens a short wait usually let's you restart and gently sail back but not this time.
I have come home and put the battery on a balance charge and it seems to be taking the charge and the puffiness has gone away.
As I write this the 5 cell Lipo is approaching 3.9 volts per cell.
My concern is how safe is it to use this battery again? I don't mind taking a chance on it giving up but obviously the worst scenario is it catching fire while sailing the boat.
Can anyone comment on this?

If it's started puffing I really wouldn't risk it.


A battery is a battery and a boat is a boat, I know which I'd rather be chucking in the bin! (Ps you should take LiPos to be safely disposed of, don't bin them!)
