Re: LiPoly fire


there are a couple of possible explanations,
One of which is that most cell phones etc operate on ONE cell LiPo or Li-Ion
batteries.
If there is only one cell, there is no chance of imbalance between cells
causing problems.
In addition, Most of these devices use a relatively gentle charge and discharge
curve where we DO tend to push the batteries in our planes to and beyond the
limits of the technology.

The more likely explanation is that LiPo fires relative to RC equipment tend to
be over-reported, and other types of incidents involving the batteries tend to
be ignored.

There HAVE been occasional reports of cell phone batteries having problems

Can someone please tell me why we never have a problem with cell phone
batteries that are lipos or liions but there is such a problem with the
use of those batteries in our planes?? IE, why do they never explode in
cell phones or in the charging process but we lose so many batteries
due to fires while charging them for r/c aplications??

Thanks!!
