smeghead28 Posted December 26, 2014 Share Posted December 26, 2014 What I saw said run them totally flat by connecting something like a filament bulb to them. Once that is done they can just be disposed of as they are. Quote Link to comment Share on other sites More sharing options...

adefirestorm Posted December 26, 2014 Author Share Posted December 26, 2014 can you post them??? I know they may be old but just put them on charger and they in storage mode with cells balanced, Just not sure how old they are, maybe someone would find use for them, don't want any money for it.

smeghead28 Posted December 26, 2014 Share Posted December 26, 2014 water and electric, I'm missing something here Nope but it should be salt water rather than just water. That is supposed to have the same effect as discharging them although I beleive you do have to score the individual cells to get the salt water to penetrate them for it to work.

-BEZ- Posted December 26, 2014 Share Posted December 26, 2014 Bucket of water, half a cup of salt, mix then let the lipos soak in the solution for at least 48hrs. The salt breaks down the chemicals and makes them inert so they can be safely disposed of in the household waste. Quote Link to comment Share on other sites More sharing options...

Don't score them, they'll go up in your face. Drain them flat with a car lamp, then salt Bath to corrode the tabs, then bin. Quote Link to comment Share on other sites More sharing options...
Oh How Original Posted December 26, 2014 Share Posted December 26, 2014 Yeah, score a LiPo cell?! O.o really? Quote Link to comment Share on other sites More sharing options...

Tug Posted December 26, 2014 Share Posted December 26, 2014 We were only concerned with the words "score" and "lipo", those words shouldn't be so close together! Especially when someone's looking for advice. Quote Link to comment Share on other sites More sharing options...
adefirestorm Posted December 26, 2014 Author Share Posted December 26, 2014 well light bulb job it is, won't play with scoring lipos or putting them in water thanks for advice Quote Link to comment Share on other sites More sharing options...
stretch Posted December 26, 2014 Share Posted December 26, 2014 discharge with bulb or similar, chuck into bucket with salt water leave for a week, dispose of in household rubbish. Quote Link to comment Share on other sites More sharing options...
Oh How Original Posted December 26, 2014 Share Posted December 26, 2014 well light bulb job it is, won't play with scoring lipos or putting them in water thanks for advice You still have to put them into salted water. Discharging them doesn't destroy the cells like the salt water does. Salted water needs doing either way. Quote Link to comment Share on other sites More sharing options...
r083rtd Posted December 29, 2014 Share Posted December 29, 2014 salt water for about 2 weeks Rob Quote Link to comment Share on other sites More sharing options...
stretch Posted December 29, 2014 Share Posted December 29, 2014 salt water for about 2 weeks Rob need to discharge first otherwise the tabs will disolve leaving charge in cells. Quote Link to comment Share on other sites More sharing options...
turok007 Posted December 29, 2014 Share Posted December 29, 2014 salty water for a few weeks. even charged ones will be fine i have done it to loads without any issues. also last summer i put a hole in all the packs that had been in soak and nothing happened to any of them.

nr73 Posted December 29, 2014 Share Posted December 29, 2014 At what point do you decide a cell needs disposing of? The reason I ask is that I have a nano tech has a lazy cell. It lags behind the other cell by some .2-.8v and discharges quicker than that cell. For the price of them, and liability factor of it sending one of my trucks up in smoke, I think I might just dispose of it. Quote Link to comment Share on other sites More sharing options...

For the price of them, and liability factor of it sending one of my trucks up in smoke, I think I might just dispose of it. Two of my 4s's tend to have pretty un-matched cells when they're discharged. One can be as low as 3.4v while another is 3.7 lol. Provided it isn't puffy, or very soft, or getting very hot, personally (just my opinion) I'd continue to use it. Cells sometimes just aren't perfectly matched, especially (I've noticed a 'trend' with mine) when they're in a faster model were the battery is under more pressure and discharging faster. Again, that's purely my opinion, it's probably wrong, but as of yet, I've not had a LiPo fire, or had to dispose of one. 1 Quote Link to comment Share on other sites More sharing options...
