Battery Safety

[LockMD]

Probably a better place to post this on this GIANT forum, but I know ya'll and respect your opinions so I am posting here :P


These 2 batteries where in the blaze of the 600 but they survived ( I think ) Here are some pics. Tell me your honest opinion, should I just toss them and not take a chance or try to salvage them? They seem okay and IF I do charge them will be outside with an extinguisher handy......If they take a charge okay, any worries they would ignite in flight?

here's the pics:


Notice the 3rd pic the white coating is broken (craked)

I really don't know enough to tell you factually what to do but I can tell you go with your gut. My gut says it's not worth taken a chance over a couple of bucks and watching your hard work go up in flames. I mean you are never really sure but it doesn't hurt to try.

Hope that makes sense LOL

All good, they caught on fire in the 600 which I will NOT do again, just wanted to salvage them to run one at a time in the 400.

Main question is if they charge without overheating, they should be fine to put in the bird no?

or is there a safer way to test/discharge them?

okay 1 more fligt then nity nite for me........talk at ya'll tomorrow.

I would get rid of them ASAP, it looks like the outside cover has holes in it, Who knows what damage there is inside those packs. It's just not worth the risk, I wouldn't even store them in my house.

I wouldn't even store them in my house.

That's the best advice, right there.
Store them outside in a flower pot or in the hole of a cinder block.
I store all of my batteries in a cinder block with a bag of sand as a cover...just in case.

It's not worth burning your house down for sure.
If you want to chance it, I would charge them in a safe area inside the same pot or block.
Then if you want to chance using them the only thing you are risking is your heli and not the house and family.

cross the leads and throw them in a metal barrel. :cheers Just a joke lock. My opinion is, if you have any reason to doubt the packs integrity its probably not sticking it in your bird. If you do use them make sure you get it on video. :thumbup:

[jayrat]

I've read hours and hours about these batteries, Wolf's right, not worth the risk!
Ditch em.

Lock give it to me.

yeah I have them outside.....sitting on metal.

[LockMD]

Lock give it to me.


I just may.......but if you burn up dont blame me.

[eugenefelisco]

Don't worry Lock I'm careful with lipos. I'm an expert in disecting things. Oh lemme ask my wife if she paid the home insurance first, if not I will put her next door driveway(just kidding).

I am not sure that is the case. My batts never get warm charging, they only get warm when discharging. I would think there has to be something out there that can put them under a load? If not, I wonder how hard it would be to build a simple device, maybe with a motor. A motor with pully to another pully (creating a very slight load). Something to simulate them in the heli. That way you could set it up on your driveway/walkway and run them to see how they manage.

Better yet, send them to Otto and let him check them out for you. Or maybe sd0 since he is ahead of both of us? :rolling

Best idea I heard all day, Otto, Sd0 whats your addresses? That'll slow 'em down (j/k)

You know, it's too bad that they don't make a "box" to check the batteries under load
like I used to have with my NiCad systems back in the70's. I had an expanded scale
volt meter (ESV) that would put a load on the airborn pack and tell me if it was getting
low on charge. Of course, you were only dealing with about a 1 volt difference from a
charged pack to a low pack, but the little meter really gave you a good indication of the
condition of the 4 cell NiCad pack. You could switch it to check your transmitter (9.6 V)
too so you really knew if you could fly or if you had to quit.
