LiFePO4 Batteries - Lithium Iron Phosphate

[Aaron]

Here is some info about the LiFePO4 batteries. 5 time the life cycle of lead acids and way safer than typical "Lithium Ion" batteries (cobalt), which are toxic and flammable.

They can be used with the Bedini SG technology or even Bedini's chargers. These batteries are constant voltage until they drop off the cliff so you get full capacity for nearly the entire time.

Lead acids need to be pushed to 15.0 to 15.2 to be truly charged and fully desulfated - these LiFePO4 batteries only need to be pushed to 14.8 to be fully charged.

At the end of this article, there is a link where you can see a video by Peter talking about these batteries and there is a link under that video where you can download a free powerpoint presentation on these batteries.

Hi, can LiFeP04 batteries receive a direct charge from flyback voltage, or does this kind of stuff need to go through a capacitor?

Hi, can LiFeP04 batteries receive a direct charge from flyback voltage, or does this kind of stuff need to go through a capacitor?

It wasn't thought that they should receive the flyback, but Paul Babcock has a 24v SSG system and he charges the output lifepo4 batts with the flyback and his system works great. I don't know what the long term effects will be but they do indeed charge incredibly well. I can't guarantee that there won't be negative effects and the batteries are expensive so go for it if you're willing to take the risk.

For sure, they do like steady DC.

For capacitive discharge, I don't know anyone that has done that with lifepo4s.

Do the LiFePO4 cells also exhibit the same type of differential rates of movement between the positive and negative charge carriers, as do flooded lead acid batteries? This would mean that these cells could also be induced to "charge themselves". It would be great to get away from the old lead weights!

Thanks Aaron - that's interesting to hear Paul's results with lifepo4 batteries - worth a try as the benefits are considerable in a mobile application.

I have 2 sets of LiFePO4 batteries
they are quite amazing,
very hard to get when I got them,
but now quite easy to get
I payed about 100% of the price in shipping
so it seems to me that the officially allowed lithium ion batteries are only viable due to them being easier to get...
