On Brazil there was a LIFEPO4 battery (Litihum based), with about 3000 cycles life (at 80%), and indicated for motorcyles.
It was expansive for a 14A 12V. It ws ALIANT, a Italian manufactur.

Now there is a other brand, SKYICH, with 2000 cycles (at 80% I think) 14A and 12V, but while ALLIANT costs 880 reals the SKYRICH costs 214 reals.

Why a LIFEPO4 it's so much cheaper than other very similar???

And the SKYRICH have better CCA value, of 888 while the RELIANT have just 245.

The 50% extra cycles of the expansive one (RELIANT) do not make the 4x price acceptable.

Can we use 3 or 4 of such batteries as energy source for a e-bike or e-trike???

If LIFEPO4 have more cycles (up to 3000) and very little danger of fire/explosion, why it it's not used in electric cars as main battery???
Is it just due the lower energy density, or something else too???
