Discharging and Disposing of Lipo's
Hey there people,
Hope you can help me out here. I've just come back after a racing at DMS and my lipo saddle packs have swollen, some more than others. What is best way to discharge them and dispose them? I want to get rid of them before going away on Monday. At the moment they are sit in the bottom of a metal bin out in the garden!!!! Many thanks in advance. Andy

You should discharge them down to 3v, either with a discharger or just with your car.
Then put them back into the bucket and cover them with salt water. This will slowly discharge them down to 0v they are then save to dispose off.

you can use your charger to discharge them at a low amperage and they will be ok, just dont use high amperage discgharge
salt water is correct but how much salt do you add?

The more salt you use the faster the cells will discharge i dont think you will be able to put too much in.

you CAN use a discharger set at a low amperage of somthing like .5 amps

I think its safer to use salt water.

cut n paste from google
To dispose of LiPo cells and packs: If any LiPo cell in the pack has been physically damaged, resulting in a swollen cell or a split or tear in a cell’s foil covering, do NOT discharge the battery. Jump to step 5. Place the LiPo battery in a fireproof container or bucket of sand. Connect the battery to a LiPo discharger. Set the discharge cutoff voltage to the lowest possible value. Set the discharge current to a C/10 value, with “C” being the capacity rating of the pack. For example, the “1C” rating for a 1200mAh battery is 1.2A, and that battery’s C/10 current value is (1.2A / 10) can be used, such as a power resistor or set of light bulbs as long as the discharge current doesn’t exceed the C/10 value and cause an overheating condition. For LiPo packs rated at 7.4V and 11.1V , connect a 150 ohm resistor with a power rating of 2 watts (commonly found at Radio Shack)to the pack’s positive and negative terminals to safely discharge connecting it to an ESC/ motor system and allowing the motor to run indefinitely until no power remains to further cause the system to function. Discharge the battery until its voltage reaches 1.0V per cell or lower. For resistive load type discharges, discharge the battery for up to 24 hours. Submerse the battery into bucket or tub of salt water. This container should have a lid, but it should not need to be air-tight. Prepare a plastic container (do not use metal) of cold water. And mix in 1/2 cup of salt per gallon of water. Drop the battery into the salt water. Allow the battery to remain in the tub of salt water for at least 2 weeks. Remove the LiPo battery from the salt water, wrap it in newspaper or paper towels and place it in the normal trash. They are landfill safe. |

Cheers
Thanks for the advice people.

If you,ve got any little chavs with a corsa fitted with huge exhaust pipe as nieghbours do your fellow nieghbours a favour. Slip the dodgy lipo in there and dispose of two problems at once.

Wouldnt it just be easier to take them to your local recycle centre, they have allocated bins for batteries
