Default LiPo Charging Pouch

Thinking out aloud, and want to try and get an answer to this question that has been bugging me.

Right, with all safety equipment, that is sold in the UK, it has to carry the Kite Mark (BSi stamp of approval), so, you invest your money in a LiPo charging pouch, how do you know it will work, how is it tested and rated, and in the end, if the bag fails to do it's intended purpose, the fact that it isn't tested, how do you get recourse?

sorry but can't answer your concerns though

I have the LP-Guard but it has no BSi Kite mark

you can see where I am coming from though. If you have a fire blanket in your kitchen or work place, it has to of passed a rigorous test to ensure it conforms to regualtions. Now, we have these pouches, which are supposed to not extinguish a combustion, but contain it.

I share the same thoughts exactly.

I could make a pouch tomorrow and sell it, without any regulation how do we ensure they are even worth the effort?

so I am not alone then in these thoughts. The reason it bothers me, is that these are sold as safety items.

Now, they have to work in a flame containment manner, as when the lipo goes, the chemicals within the cell, combust on contact with atmosphere, so the bags musn't be air tight, as once it has burnt the oxygen in the back, you open it, and poof, up it goes again, so they need to be able to hold together whilst the combustion goes on.

People also need to use them correctly. I've seen many people using them without the flap closed properly

if the flaps open, might as well have the cell out. As it stands, and this isn't enforced by the BRCA, it is just a recomendation (and in the light of NiMH's still going pop 'cause you looked at them wrong'), seems OTT. There is nothing to stop me, going out and buying a plumbers soldering mat (the ones used to protect the walls from flames), stitching it together, bit of velcro, and I got a LiPo sack.

Just bothers me that, if the item is such a SAFETY item, there is nothing in place, it appears, that don't stipulate build regs, flame resistance times etc etc

This is from the Electric Common:

5.3.1 All LiPo packs used for motor power must be charged inside a “Lipo Sack” or similar
fire mitigation device proven to withstand a minimum of an 8.4 V 5000 mAh lithium
polymer pack failing destructively without showing external flame. EFRA will include a list
of recommended charging containers on the approved battery list.

so that rule is perfectly useless, as the limit is now higher than 5000mah

Yes it looks that way :-)

Perfect when they change one rule and doesnt look how it may effect other rules!

Nope, that's to try and prevent damage to the cells that will cause it to become dangerous.

the rule may be a little curious, but that's more than un-called for, and a comment such as that really is out of order.
