I've checked that out along with the equations and still don't get it. first off they're equations are questionable when run up against the graphed data. second when compared to the weight of the actual batteries I have to carry when using li-poly as compared to the actual weight of ni-mh cells the nimh cells are lighter. so what is this energy density stuff anyway? > Date: Thu, 22 Dec 2005 09:01:09 +1100 > From: Jonathan Paxman <[EMAIL PROTECTED]> > Subject: Re: [LIB] u100 battery life engineering problem > > On 22/12/05, [EMAIL PROTECTED] <[EMAIL PROTECTED]> wrote: > >> true, external temperatures affect li-poly but do not affect nicad/nimh >> chemistries unless they are in the +120/-20 range. gotta wonder why the >> industry uses an old technology like lithium when the nickel metal is so >> much more superiour in every way. > > Two words: energy density. > > Jon > > > >
