Model Forum / Radio Controlled / Air Models / May 2004Mobile phone batteries....
I have seen quite a few single cell li-poly mobile phone batterries for sale on ebay at very good prices. Is it feasable to strip off the plastic and solder them together to make a cheap Li-poly batttery pack? : I have seen quite a few single cell li-poly mobile phone batterries for sale : on ebay at very good prices. Is it feasable to strip off the plastic and : solder them together to make a cheap Li-poly batttery pack? Are they li-poly already? All phone batteries that I've seen are li-ion, they are in metal cases (not in mylar pouches as li-poly), which makes them heavier per capacity, and also their electrolyte is liquid (not solid), which makes them far more dangerous in case of overcharge or short. I have one li-ion pack for Pico Stik, but in the future will stick to lipolys. -Tapio- My last two were/are LiPo. Both Panasonics. Latest one is the new X-70. -- Paul McIntosh http://www.rc-bearings.com > : I have seen quite a few single cell li-poly mobile phone batterries for sale > : on ebay at very good prices.

That's odd, my X70 has a Li-ion battery! 3.7v 680mAh  SignatureJohn P. - who flies on Epsom Downs, UK. http://www.flyrc.org.uk/ I'm sick of spam, so replace 'nojunkthanks' with 'john' if you want me to read any e-mailed reply! You are correct! The sheet at the Orange store said it had a LiPo. -- Paul McIntosh http://www.rc-bearings.com > > My last two were/are LiPo. Both Panasonics. Latest one is the new > > X-70.

Yes, but they are often not very satisfactory - even if you strip out the protection circuitry they tend to not be capable of high current delivery. |
