Lipo sacks - RC-Monster Forums

Hi everyone, When charging two lipos, should I buy two seperate lipo sacks to charge them in? Or charge both lipos in one sack?

in all honesty i think a ammo case from the surplus store works fine....maybe even better. They are about $10 at my local shop

One lipo sack for each battery. Ammo boxes are NOT safe when things go "wrong".

ya, one in each cuz if theyre in the same sack n 1 pack goes boom, the other one is at risk of doing the same even if theres nothing wrong with it

X2 - My ammo boxes are going to hold up to much more than any of those lipo sacks.

It is the same principal as letting a firecracker go off in your "closed fist". The ammo box will not give and so the energy will not disipate. Same holds true for fire safes.

Have you guys seen a vid of a lipo sack in action? It totally puffs up (contains the flames) and allows it to vent (just smoke) safely.

For all the money we spend on Lipo, BL, etc. this is good money to spend on safety. By the way I am in no way connected with this company.

In fact if anyone knows where to get a good deal on them I would appreciate it. I need to get two.

I use the lipo sacks, I have 2 white ones from maxamps.com (shutup) and 2 black ones from impaktrc.com. I use 1 to charge 2 lipos as I use the 0610duo, but as Pedeboi said 1 of them flames you are out 2 lipos so best to charge in seperate sacks. I read before the ammo box or safes dont disperse (sp?) enough oxygen and turn into bombs if they flare up. Enjoy that though, im not here to tell anyone what to do lol

That's why I drilled some holes on my ammo box. One hole is big enough for the connectors to go through. The holes will dissipate the smoke letting off the pressure and preventing the box in becoming a sharpnel.

Best of all, the ammo boxes were free. I got them from the shooting range on base.

wow 2 good arguments. ok how do you route the wires to the ammo box; or do you leave it open to vent the pressure?.
Does the lipo sack smother the fire, and the ammo box provide a safe burn area?

damn took me 5 minutes to ask and the answer was there

If I was using an ammo box, and Ive thought about it, Id have a sack of sand near by. The lipo sack is like a firemans jacket and you could grab it and throw it outside ( (providede your doors close or Id revert to the sand) no water smothewr and roll... To get those lipos charging in an ammo box you would need to make a long ass charging cords or cut some weird holes in it. Notice my bias

I have a lipo sack and honestly don't use it for charging! If I noticed damage to the pack I just wouldn't charge it. Charging a Lipo with a balancer is pretty safe as long as the pack isn't damaged. I store my Lipos in the sack, and honestly I usually have a couple that aren't in it. Call me a ignorant but I just don't see anything happening to packs that are in good condition!

jayjay283 · 12.29.2008, 02:47 AM

well revo I wasnt going to go there, I thought stuff on the net being sort of in concrete should be good advise LOL, I never use a lipo sack, I rest them on top of them as I paid $40 for them, if I get around to it, but id rather watch the puppy puff. I only charge my lipos when im close though, as I blew up a 7 cell maxamp NIMH pack that scared the crap out of me. Since I bought the 0610I duo and a 36a I have never had a blip or .02v off charge. Ignorant maybe but i do have those lipo sacks close to use as pot holders if crap happens, but in over 400 combined charges ive not had a fart

that too, i am ignorant in that i have the hyperion 0610i and 25 amp power supply (radio shack but iv'e heard its actually made by a good company forgot which one lol heard it hear though) i spent the money for a tiny bit of peace and mind. i know its not a garantee but it helps. i am also in the room when i charge, as my tiny apt does not let me leave the room

from my understanding you have to MAKE lipos blow up. still from my understandig

So many paranoid people out there! Honestly a little common sense goes a long way with Lipos. If it's damaged simply don't charge it and always use a balancer!
