My lovely DX magicshine P7 battery pack just caught fire burning one of my fingers in the process, ouch!
It was in my bag FFS had to throw it out the window of the train just in case it exploded.
My finger hurts

Blimey, you were lucky - I've heard of laptop batteries catching fire...

WTF? :shock:
And I thought the thread title used flaming like in 'flaming galah'. Here I was planning to make a hilarious joke about how you're doing something wrong if your batteries are on fire.
Look how well that turned out...0 -
Jesus. Lucky you didn't get shot as a terrorist!0

And I was considering getting one of these too.........
That's bizarre, especially as it was not charging at the time, wonder what caused it.
I instead invested in a pair of C1 torches and a P7, which has already died it would seem, or come to me faulty at least :?
Glad you got away relatively unscathed - guess you are now looking for a new battery pack?
I think you may find some solutions towards the end of this thread as there are some UK distributors: http://www.bikeradar.com/forum/viewtopic.php?t=12660192&sid=2f88556a8332080e006541515a221ab0
Or are you going to contact DX for a free (?) replacement?

I dropped the battery pack very gently today, no visible damage, so Magicshine owners beware of dropping your packs.Rule #5 // Harden The Feck Up.

Sorry to hear of your injury itboffin, I hope it clears up soon.
I have one of those lights and build quality, particularly of the battery pack is my biggest concern. All main stream rechargeable battery technologies store a lot of power which if released over a short time can generate a significant amount of heat. I inadvertently shorted out an AA size Ni-Cad battery some years ago and was amazed at it’s ability to turn thick wire red hot, certainly hot enough to start and sustain a fire.
Li-ion batteries are used in most high power bike lights and are inherently not as robust as earlier technologies, they don’t tolerate over charging or excessive discharge well, and hence they require more sophisticated chargers. Physical protection from impact is important as well as the quality of the electrical connections and circuitry to help to minimise the risk of short circuiting in an impact. It is possible that in dropping your battery a short circuit occurred in the battery assembly giving rise to over heating, smoldering and risk of fire. It is certianly some thing to be aware of with all rechargeable batteries.
Having recently had a heavy fall on my bike in the ice I should perhaps inspect my battery for damage!I ache, therefore I am.0 -

You were lucky that you were on a train that had a window that you could open :shock: and better still you weren't in the US with a trigger happy cop :shock: :shock: How did your fellow passengers react??0 -

While you were throwing ot out of the window, you should have done it with a loud shout, I am sure a few of us would have visited you in jail over the next 15 years....."Encyclopaedia is a fetish for very small bicycles"0 -

Think I know what may have caused this; looks like the same thing may be happening to mine...
While pulling out the plug last night to plug in the charger, I noticed that I've damaged the cable (on the battery side) where it enters the plug; the plug is such a tight fit that it's quite hard not to do this if you unplug it every night. The insulation has split, and I can see bare copper inside.
On further examination it looks as though the insulation on the internal wires is much thinner than the black insulation forming the outer of the cable. It's not hard to imagine that you could damage the internal insulation whilst the outer one remains intact; if you did this you'd have the potential for a short circuit but with no visible damage.
Off to Maplin this lunchtime to buy some replacement connectors; planning to put two on, so that I can plug in the charger without disconnecting the lamp. Charger plug is a much looser fit (presumably because it doesn't need to remain waterproof) so this should be a better long-term solution.Pannier, 120rpm.0 -

Will look forward to hearing about that too. I always unplug my lamp overnight (once it has been charged) because I'm concerned about draining the battery with the green indicator LED on the back, should I not worry about that? I commute to and from work on one charge (3hrs riding approx), guessing I'm nearing full drain but I still show green so probably have a bit to go still.0 -
I only just got mine so I guess I need to be careful.
I always pull only by the body of the clip rather then the wires as I always worry about damage to cables (broken far too many power supplies before I guess.
I think I might look for a way to add more grip to my connectors.Giant TCR advanced 2 (Summer/race)

There was a story a while go that if you carry a pp3 battery in your pocket along with some change, a 5 p piece can lodge between the contacts and cause it to burst into flame/set fire.
Trouser pockets are definitely NOT the place you want a fire, and even more so now after recent events if you are on a plane.
