New lipo charge bunker

[mark christopher]

Im not a fan of saying lipo are dangerous, so if as a user you feel you may make an error, or you know your charger defaults to NIMH, or you dont know the difference take a look here

That will soon clear the pits :0 just shows how much energy these things store

[russmini]

Yep, that went up very well, but was contained extremely well at the same time.

May be a good thing, bit fiddly, but could save other equipment and potential harm to people...

[eyeayen]

How much damage would that have done if it had been in a Lipo Bag...

That looks a solid bit of kit but could everyone afford one ?

[eyeayen]

Okay so I didn't check out the link first and to be fair I was expecting them to be considerably more than $23.95 !

[dodgydiy]

well thats a bit of a kick up the arse to everyone who slated the idea of using a £2 military surplus ammo box like mine. metal box isnt brca legal though, "its not a lipo sack" even though it does the job far better

[Battle_axe]

the FAA says for a lithium-ion or polymer fire there is only 2 effective methords Haylon or Class D fire extingishers, potentialy with enough heat sand could make it a whole lot bigger, however in a smaller fire sand may contain the fire long enough to burn out.

Water, Foam, CO2 are all a bad idea

Halon went out of use a while ago in domestic use its nasty to the enviroment i think I Stand to be corrected if you have one i think your local council or fire service will advise of its safe disposal

I had one for a while until during fire training at work i mentioned it to the trainer who kindly exchanged it for a nice large red Co2 one

It's a question of energy. A receiver pack will effectively go phut and that's it. An RC main drive battery does all sorts of pyrotechnics as it can power a 300 watt motor. An F1 battery capable of delivering up to 35kW over less than seven seconds is just so much energy that the best way to extinguish it is to eliminate oxygen from the area - CO2 or Class D.

CO2 replaces the oxygen in the surrounding area of a lithium fire so cutting off its source of combustion. Class D extinguishers with copper base combine with lithium to form an alloy on the surface which acts as a barrier and prevents the oxygen reaching the 'raw' lithium.

As you say, we can use the sand as it cuts off the oxygen, but the cell does not have enough energy to burn through it. HTH

Got one today, suprized how heavy its is, just got to assemble it, see you at Tamworth Pete.

Click link in first post, once assembled it ain't weak will post pic later

You gotta love the irony of all this...

The man who pushed us all to go LiPo because it was safer than NiMh is now doing what we all said we could do with NiMh, charge them in a box, but were shouted down as idiots by... the man now charging his LiPo in a box!!

The advert describes the box as needed because the only two times your LiPo can fail is during charge and discharge.... despite there being issues people have had with them sitting in cars and houses. It also describes the box as bullet proof and made from 304 stainless (the cheapest grade I believe)... someone ought to tell the Army - they spend a fortune on Chobham armour for that purpose and seem to be wasting the taxpayers money again!!!

Am I the only one who think someone's been had?

Pete
At the moment im forced to charge them in a "lipo sack" or container that can retain fire by the BRCA, so just because i think there safe or anyone else for that matter makes no odds, to be at a brca club and charge lipo i/we have no choice. While at home i charge them open and uncovered!
im happy to turn up at the next 12th national meeting and not use a pouch, because in my opinion thier safe , how long do you think ill last before thier "jobs worth" safty officer "forces" me to use a pouch or leave the meeting...

Please point me to where i said folk were idiots for wanting to charge Nimh in a box i will not dispute i may have called you one in the past though.


The only ones who have bee "had" are the ones forced to buy a lipo sack, that you have confirmed does NOT retain fire as in the written BRCA rule

I hear "teamSlow Ones" have a new lipo safe bag, as thier logo says its what is says on the bag... Have a good xmas you GOM

Metal conducts heat and electricity very well.......
