[RE-wrenches] Lithium Ion Phosphate for grid back up

[Darryl Thayer]

One of the advantages of LiFeP is the fast rechange rate.  I have found that fast recharge is very hard on LA batteries, if they are recharged faster they fail sooner.  Perhaps Jamie or others could answer is there something that can be recharged fast?  Capasitors are almost impossible to work with.  Lead carbon? Ni Magnisum Cobalt?

I 2nd what Ray Waters is saying. Much too soon, BMS will be an insane challenge, we rarely care about weight and footprint like the EV's do. Returning defective cells to China IF they accept responsibility for the failure - I don't think so!! Sex appeal is overwhelming good judgement, one of the curses of our industry.
