I have an extremely dubious looking Lipo. Took it off the car last night and one side of the outer case has come apart by a good ¼ inch at one end, the cell at that end has clearly expanded.
Is there an official recommendation for dealing with this? I guess I could
• Bury it in the garden –sometimes easier said than done
• Lob into a neighbour’s garden who I am having a planning dispute with
• Tape it up and sell on on Ebay
• Post it to the people who organised the issuing of Olympic tickets
• Post it back to the retailer and ask for a refund – the most recent of my Lipos
I am certainly not putting in my 1:1 scale car and driving it anywhere.
It is currently on the patio well away from anything else.
Help

Yeah I saw the end result (LOL) but not the inititiation. Living in a Thatched cottage worries me with that disposal method though  |

salt water, add salt to water until no more salt can be disolved (cant remember the scientific term for it)
then put the lipo in that - that is what I have heard before,

Do as Rueben said with the salt water and cut any wires off. Leave in the water for a couple of days. When you first put it in it just bubbles a bit out of the terminals but nothing much.
Then take it out and dump it. If your really not sure you can always volt test it first.
This is how I did my one and it was fine.
Hope this helps mate.

the best method i have seen was courtesy of mr baldry.... I must admit it did go up better than I expected and all i did was give the silver foil a small puncture with a blade!(to prove a point to someone) This is something to be weary of if you are trying to split a casing for repair. This old practice pack had swollen quite badly.TBH It was my own stupid fault it had been left fully charged and forgotten about for quite a while "easily done"  And befor an outsider jumps down my throat,I have been trained in the handling,transportation and the use of explosives ,and the pack WAS placed in a sand pit for the demo!! Aparently dropping the pack in a "saturated" conductive salt solution will very slowly discharge the pack keeping the chemical charge/discharge process to the bare minimum there for reducing the risk of fire |
