wasn't A123 the builder of efficient LiFePO4 accumulators, good candidate for rough accumulators, less dangerous (don't explode, or burn), near as efficient, especially on duration...
I don't understand why LiFePO4 does not get success. it is easy technology, easier to use than LiPoly or LiIon+Co 2012/8/17 MarkI-ZeroPoint <[email protected]> > I heard about the Chinese bailout of A123 from a business man I know…**** > > ** ** > > On another note,**** > > I stopped by his office late morning to chat, and I brought my watts-up > energy meter to verify a new type of light that he showed me last time I > visited him.
