You really should use more time on keeping your RC's in fit condition and less on mirroring the YT archive in here.

Look who’s sharing!! Yet You, have time to reply, why? Haha
You watched the video, and found it silly no doubt. Breaking the monotony here, was the goal.

If it wasn’t pouring rain here, I would be out, burning off the back wheel, on my Can Am SpYder RS-S.

My seven drones are all doing fine. Two rc helicopters as well. Very fit indeed.Haha.
This morning, I have been working with my pink wrigglers. I started a vermiculture, worm composting bin. I had to feed them and stir up the bedding...

Actually I have several other hobbies aside from RC modeling.
Archery and bow hunting are a favourite pastime too. I do keep all that gear pristine, when not in use.
My Leather work carving/tooling/stitching, is also something that keeps me mentally occupied.
My regular dslr Nikon D800 with 80-400mm lens attached. Great for “BIRD” watching. Smile

What about yourself. Other interests aside from your DJI products and services? Love to hear what active members here enjoy, spending their precious time doing for fun and or profit..

Do often work on that mind too. Keeping it active and excersised.

Why didn't they make themselves  useful and maybe grill some burgers over it.

Sounds delightfully delicious to me.


Yeah, make mine a nice thick grilled Alberta bison burger. Thanks.

Throw on some sweet Taber Alberta corn too. Ha

So I guess this is not the proper way to dispose a defective lipo :-)

So what is the proper way?
We have these recycling places in town where you can dispose anything. Some stuff only for a fee.

What happens if I crash my drone and the lipo starts burning?
I need to wait till its over and take it in my car to one of these places?
I don't wanna set my car on fire ;-)

Drowned it in a Salt bath...

Then to the recycle station.

If you are visiting your local hobby shop, they will dispose of it for you.

Now I need to always carry with me a metal bucket, a gallon of water and a pound of salt?

Semi retired actually. Though I do have several other pastimes and hobbies.

Aside from my Mathews Archery/Bowhunting, Leather-crafts, DSLR photography with my Nikon D800, slingshot practice, and others.
Recently I began a vermiculture or worm composting bin. If they multiply as expected, I could start a small pink wriggler, worm business. Ha

Water would actually be a very bad idea for an exposed battery.  Remember school science class?  Remember what happens when you put lithium in water?

When I went to school there were no Lithium Batteries ;-)

The Saltwater method is actually a misrepresentation of advice that was given in the early days of LiPo hitting the hobby scene. Like many mistakes it has become 'fact' by its too often repeated advice.

The actual method recc'd was :
''The original proposal was by Fred Marks when they were first selling Kokam packs and had two components:

1) Discharge the cells into a resistive load until they are flat.
THEN
2) Slit the cell and put in salt water in order to chemically neutralise the contents.

The salt bath had nothing to do with the discharge process.''

Therefore modern day advice is to :
Discharge through resistive item such as lamp or resistor till battery is zero.
Remove plugs - twist lead ends together to maintain dead state.

Dispose of via recognised hazmat waste disposal.


Saltwater as in table salt in water is actually not a great conductor as people imagine. It would initially discharge the battery at a reasonable rate - but as the battery goes down and its energy value reduces - the high resistance of the saltwater mix would slow it down too much.

The only real way to discharge is via suitable lamp or resistor ...  Don't forget to get to true zero is actually infinite time. To get to practical zero is the aim. Second that zero energy of a LiPo is stated as 3V .... but you need to go down to as near 0V as possible and most charge / dischargers will not do that as they have cut-off at around 2.8 - 3.0V.

Here's a simple discharger I built for about $10 ... caters for LiPo's 1 to 6S ....



Simple enough to fit a DJI socket from eBay to it ...

Water is the recommended way of putting out lithium battery fires, it is the only way that has much affect.
The water works by cooling the battery and stopping the flames spreading to surrounding material.

There is no lithium metal in a good lithium battery, so your school science class is not relevant.
