LiFeYPO4 means Litium ferrum Yttrium Polimer (Phosphor) the ferrum gives the security as far i remember

 

I read a lot about it a while ago and I will give it a shot. In a few month when the car is done.

Of course I will again research bofore i buy but it will be a litium...... one

lithium iron phosphate batteries have been a big splash in the motorcycle world for a few years, primarily due to their extremely low weight and small size. in the early days the cells were all made by one or two companies and re-packaged in different casings by other companies and sold under various names. we used to buy dewalt battery packs, pull 'em apart and link them to make our own cell packs. i've built a few custom bikes with these and they do work well, however there are a few caveats... 

  • the cells must be kept in balance, which means you need a special charger and the better batteries have electronics in them to assist, along with a special multi-pin plug for the charger so individual cells can be monitored and charged accordingly. 
  • these batteries lose a lot of power when cold, so you can wind up with what seems like a dead battery on a frosty morning. some riders have quick-disconnect batteries and keep them inside, others have found that turning on the headlight and drawing current heats up the cores to get them going. the battery isn't dead though, just needs to be warmed up.

again, the primary advantages are weight and size, which make a huge difference on a race bike, but i don't think either mean much on a street car... i actually reverted back to lead-acid on my touring bike as it's a less finicky technology and the reliability factor is way more important on that bike than shaving a few pounds.

 

i'm not trying to say LiFePo batteries are no good - they are very good, very powerful, very small and insanely light - just saying that those benefits may not be right for a street car...
