Same here. What'd you end up doing?

Time to replace the battery.

Damn, your old man is such a badass 😎, he knows whats fun 😂

Mine was doing the same thing. Was also showing 5-6 psi with nothing connected. I took the case apart and unplugged the air sensor (follow the rubber tubing) and turned on the air pump. It worked with the sensor disconnected. I reconnected it and it seems to work fine now.

mine is doing the same thing. My dad took it apart and a washer/O-ring is destroyed on the piston not found anybody that has replaced this. Can't measure mine since it is completely destroyed it.

@@kanistas sure, I’ll help as much as I can. Did you shine a light on the battery terminals to see if there was a + and/or - formed into the plastic? Or is it the wires of the charger aren’t well marked? If the + and - marks of the battery aren’t helping, or aren’t present, if you could send me a picture, I might be able to help more. Send it to peterzum@yahoo.com

I want to see if I can use something to dissolve the lead sulphate between the plates or on the plates and then give the battery some fresh sulphuric acid

I’ve seen some videos of adding Epsom salt (Magnesium Sulfate heptahydrate), and then heating the battery by feeding the battery current from a current source like an arc welder. So all that is pretty dangerous, it could create an arc flash, if the current is started out too high if I overestimate how much current it can handle so I would want to start with a real low current probably not even on an arc welder and then turn it up to see how much current I actually need to heat it, but it seems really dangerous to me to hook it up to an arc welder directly, and then just flip it on without ever doing any experimentation to see what kind of current is the safe zone.

did you leave the battery sitting and not charge it at least once a month? You could try to recondition the battery with Noco 12v trickle charger.... .. If you left it unused for long periods... it probably sulfated away.. I have the model before this one... I think the first CAT model that costco carried. Still works but doesn't hold as much charge in the past... attempting to condition it the next few days with my 12v AMPEAK charger.... trickle mode,..... I might pick up the trickle charger Noco one...

How?

Do you have a part number for the lithium one that you used?

@@tigeroftheeye7121 we got it dierctly from abdouexpress i will see whch one it wa s soon GOd willing

Can you share the battery model?

Bad idea, Li-ion will explode while charging... It requires different charging regulator

There’s a pretty good chance that that is the case. Another common thing is, there’s an AC adapter inside of it that goes bad and you can just replace it with a similar AC adapter with the same voltage and current rating, I have used an adapter before that was slightly higher voltage and it seemed OK. I was a little worried that it might’ve been over charging the battery, so I would always set a timer and just unplug it when I thought it was probably full enough.

But fix em up and sell em on Craigs list or something If you lived nearby I’d buy them from you myself if you wanted and resell them, but I’m moving right now anyway so I’m too busy for now. But yeah Fix em up and sell em Do you get Amazon returns or something?

Yeah I made it more out of a scientific curiosity I wanted to see the motion of the wings during flight

That’s true, and I should have been safer at least so it looks safer if nothing else. It’s just after trying to get propane tanks to actually explode, I got a lot less worried about them… but that could be complacency too…

Yeah that’s what I did. I remember checking the stones to make sure they were clean from all dirt and dry, but I imagine you probably did that. they were roundish stones out of a stream I think. What I can remember right now that they could’ve been from my gravel driveway, but still had large flat regions, but I think they were rounded off stones from a stream, but dry, and they had been dry like 4 days I think. if you put your rocks in a toaster to dry them, just be sure you do it real slow-like so that you don’t boil the water and blow it up and hurt yourself but I imagine you probably know that too. I think they were about the size of putting my thumb and pointer finger together to make a circle a little bit smaller than that. Oh yeah, it’s about as large as I could fit in with the opening of the bottle neck. Oh yeah I usually do it with really large plastic bottles of generic Tylenol like the 2000 count or 4000 count or something like if you were to fill them with water it would probably be about a half liter maybe a little less. I don’t remember how many rocks I put in but I think it was around eight… there was lots of air space, but more than four rocks, but it was all packed very loose. There was plenty of open space for the rocks to bounce around. The thing I was most worried about was when I accelerated my arm for throwing it the sudden acceleration needed for the throw, might make it blow up in my hand , that was the part that I thought was the most dangerous One last thing I just thought of I think I wrapped the bottle in a little bit of tape. I’m not sure if that matters I don’t think I would’ve wrapped it in very much tape and some of the “noise makers” i made in the past, I didn’t wrap in any tape at all, except to hold the lid on and keep it from moving Because you don’t want anything to absorb impact and I was also thinking if I put on enough electrical tape, I would’ve added some mass to it and made it hit the ground with a bit more momentum to transfer to the rocks. When I mentioned the tape thing it made me think About what tape I used. I used mostly electric and duct tape in-general , I was thinking a thick wrapping of masking tape might be cushiony but elecical tape would be denser and bouncier I think so there could be some help in the type of tape you use, but i don’t think tape is critical. I think if things go right that it’ll work fine without tape.

Oh that’s a good idea, I’ve always hated the static electricity of plastic. I do use recycled paper a lot for pouring and funnels, but that’s a good idea for mixing, is to use cardboard or something non-staticky that I can burn

@peterzum you'll really hate it when it sets off those very sensitive chemicals in your hands. 22 sensitive tannerite comes with static free bags and mixing vessels. Dont make assumptions that your little ziplocks wont create static. You are playing with some really powerful fire. Act accordingly. Most youtubers will tell you not to mix more than .5g of flash powder in any composition. It is very volatile and very sensitive. Even the smallest static charge can set off any of the compositions you mixed here. Friction and plastic create static. Please inform yourself on the proper way to do these things before you hurt yourself. Just buy paper firework tubes. You can pour chems, mix, and destroy, all in the same vessel. Far less risky than what you are doing here.

@peterzum plus, if you do it right, the paper vessel is designed to contain the explosion, just like in a firecracker. It will blow up with more force when confined in its vessel. Flash can "self confine" as well, most compositions need under .5g of pressure to confine. but sealing that Shockwave in a vessel makes for a fuller detonation, and less deflagration. less smoke if that's the effect you're going for. But more boom.
