Lipo indoors
« on: January 05, 2019, 06:49:51 AM »
Hi. We are going away to the Sun for a couple of weeks. Just in case it gets very cold in the shed, I have moved my half a dozen 3s Lipid indoors. They are all at storage voltage. Should be all right whilst away ???
Cheers

They will be fine. I remember John Emms (who owns Puffin RC - one of the original specialist electric suppliers) used to get amused when people talked about treating lipos as if they were stored nitroglycerine or something. H pointed out that in his storage area at any one time he had about a thousand lipos stacked on the shelves...

If they're going to fail it will be during charging or use, so never leave lipos unattended while charging, but don't worry yourself into a premature bisto* over it.

To be honest they'd have been fine in the shed anyway.

Might be worth  tipping off the local fb.....just in case... :nananana:

Seriously, if they are stored in a cool place they should be fine. Go enjoy your hols and top up your tan while we all freeze.... :uk:

So why did I find some that had been looked after and put away at storage level voltage all swelled up and looking like they were on the verge of blowing up?

They had probably been in that room for about a year and had never been worked hard or taken too low. Nor had they been subject to any great fluctuations or extremes in temperature.

A clubmate had left several Lipo's  at storage voltage in a lipo bag for some months untouched by anyone in a spare bedroom.
He was recuperating from surgery, and woke up one night to a strange smell.
The lipo bag and its contents were terminally burned, and the table it was on was scorched.
The good news was that the bag did a pretty good job, especially as the event took place in the middle of the night!
Such events may be very infrequent and defy logical/ technical explanation but they do happen!
I would not take the risk.

I have heard many such stories, and would not keep them in the house. Yes the biggest risk is charging etc but a model shop near me (now sadly gone) had a brand new one still in the packaging swell up to the point where it was risky even touching it. Only time it has happened to me was at the RC hotel, where I landed a model, tried to taxi back and nothing. The battery was smoking...so I would say the risk is small, but certainly not worth taking.

I keep mine in the workshop - separate from the house - in a B&Q 'safe' for want of a better description. Cost about 85 about 12 years ago when I bought my first lipos. It is claimed to be fireproof, weighs a lot - the walls, lid and base are steel and over an inch thick - and houses about 50 lipos of various sizes. Empty, I can still lift it, full I can't.

Put them in the oven and close the door, then stick a 'lipos' label on the handle.
You'll enjoy your hols better knowing they're in a fireproof place,
Regardless of what John Emms said Pete, Lipos have been known to spontaneously combust.
My friend Wayne Giles is a professional power systems engineer, he designed all of Bob Smith's
lipo test equipment and the ESR meter sold by HK was a joint project between Wayne & me.
My point is, Wayne absolutely knows his stuff where lipos are concerned.
He had a lipo catch fire, in storage, not on charge, not recently charged, not been abused in any way - it happens, and those who say it doesnt simply havent experienced it yet  :af
Cheers
Phil
