Tim Posted July 20, 2007 Share Posted July 20, 2007 Li-Po batteries are safe to use and store IF they are single cell ones. There's a Li-Po battery in just about every mobile phone, in every Picco Z heli and Bluetooth headset! It's inbalance in multicell packs that cause a problem. I had a pack short out in pocket and it burnt my jeans/thigh/hip and it didn't even 'go off'. If you are respectful of them and don't put multiple cells in your pocket with your keys, it'd be fine Link to comment Share on other sites More sharing options...
Hpi_matrix_stock Posted July 20, 2007 Share Posted July 20, 2007 (edited) You hear alot more lipo's go boom then NI-MH's Really? Where do you hear about them? Iv heard of alot more IB batteries exploding then lipo's Edited July 20, 2007 by Hpi_matrix_stock Link to comment Share on other sites More sharing options...

If you are respectful of them and don't put multiple cells in your pocket with your keys, it'd be fine nope Mobile phones have Li-ion (Lithium-ion) Which means sumet different to Li-po I cant remember what a polymer is - been a while since i did chemistry Ziggy Link to comment Share on other sites More sharing options...
JamesChatz Posted July 20, 2007 Share Posted July 20, 2007 Its basically the same type of battery, just a different material in them. And im the same as Greg, heard more about the Ib batteries going boom than lipos. Link to comment Share on other sites More sharing options...
Tim Posted July 20, 2007 Share Posted July 20, 2007 Ziggy - "Ion" is a polymer. I'm holding a Li-Po battery right now and it's warm from 'thumb action', should l chuck it out the window? Link to comment Share on other sites More sharing options...

Ion is not a polymer. A lithium ion battery stores the lithium salt electrolyte in an organic solvent (normally something along the lines of ether) and not a polymer as you make make out. However a Lithium Ion Polymer (LiPo) on the other hand uses a solid polymer composite to store the lithium salt electrolyte (normally something like polyacrylonitrile) which is a polymer.

Nice copy and paste from wiki Oh and if you had bothered to read the rest of the wikipedia page, you will of read that lipo batteries still contain a bit of an organic solvent......

And if you'd of read my post in the first place you'd of realised the part about ether in LiPo's was negligable, hence why it wasn't included. We weren't discussing whether LiPo's contain ether, we were discussing what the lithium salt electrolyte is held in. But I guess you just didn't bother thinking on that one.

Nick Posted July 21, 2007 Author Share Posted July 21, 2007 I found out a little more about this cell. It was a bad cell, the voltage was very low and slowly dropped to 0v, once it got to 0v it releases a gas (which causes the foil to expand). It is not dangerous at this voltage. Apparently it's only dangerous if it's high voltage/over charged. Link to comment Share on other sites More sharing options...
Garry Posted July 21, 2007 Share Posted July 21, 2007 What brand cell was it Nick? Non-Kokam/Flight/Trakpower cells aren't worth the risk TBH. Especially non-cased ones in cars. Link to comment Share on other sites More sharing options...
Nick Posted July 21, 2007 Author Share Posted July 21, 2007 They were TrueRC ones. Very cheap. My Flightpowers are really good, although, you can get 3-4 packs of the cheap stuff for the same price (which is the real eye catcher). With batteries, you defiantly get what you pay for.
