[NSRCA-discussion] Lipo disposal

[Robert L. Beaubien]

I purchased a 25w 47ohm resistor that I soldered to an XT60 plug.  After discharging on the charger, I plug the resistor in and let it sit on the porch for a day.   Then simply cut off the battery/balance leads for parts and dispose of the battery in the local battery recycle bin.  Once totally discharged, nothing further needs to be done.

To discharge old Lipos, I put them on charger to discharge.  Then plug them into an ordinary 117v, 250 watt heat lamp.
From a discharged state, a few hours seems to kill them totally.  Lamp gets warm not hot.
A day or so later I repeat the discharge with lamp.

 (To adapt the lamp to lipo, I started with a hardware store adaptor that has female threads for ordinary light bulb,
to standard wall outlet prongs.  I added a cord with heat shrink to fit the outlet prongs, and my brand Lipo plug)

I also have a smoke detector in my in house shop.  It's not a solution, but increases warning time.

I'll take the 10 fully charged packs off your hand to dispose of them for you. You're on your own for the older ones.

Actually best bet is to bring them to one of those battery stores, they generally take any battery for recycling. Supposedly you can also discharge them in a saltwater bath and then just throw them out.  Apparently they are safe in a landfill, I guess as long as they are discharged.

This discussion made me take inventory.  I have 31 old 10s (2 x 5s)  packs in my garage.  Some go back 7 years when I started flying electric.   One pack was ejected during a snap roll at altitude. One pack was involved in a mid air.  Both those packs are badly damaged.  I really don't know how to get rid of them.  I also have 10 fully charged 10s packs in my workshop.  Perhaps this would a good time to share ideas on how to dispose of them.
