LiFePo4 for DUMMIES

The accepted industry practice has been to not float charge. If you look at integrated circuit Li chip sets few allow floating.

Equally many acknowledged experts and research maintain ( for...

Re: LiFePo4 for DUMMIES

I read that whole paper , all 110 pages very interesting work on a masters thesis.

Accepting his results it would suggest that maintaining a float voltage at below a higher stress voltage would...

LiFePo4 for DUMMIES

The inside of a winston battery , it's not a cell, is a series of prismatic pouches without some of the protective outer skin. But they are built from a series of Li cells in parallel ,( with the...

Re: LiFePo4 for DUMMIES

The is sometimes a kind of denial that Lifepo4 "large" prismatics are somehow "different" for Li technology. Nothing could be further from the truth. What is evident in various LI technologies, and...

Re: LiFePo4 for DUMMIES

Absolutly, but I was trying to suggest a bare minimum system that can be safety added to an existing system. My suggestion assumes no modification to the charge systems and most current internal...

Re: LiFePo4 for DUMMIES

Because many alternators have no easy access to the field wire., its easier to wire up a simple load dump power resistor ( like those used on wind generators), use a crossover contactor/relay , make...

Re: LiFePo4 for DUMMIES

The big thing with roll you ownLifePo4, is that not all the systems are conveniently off the shelf or perhaps require a bit of modification.

But its not that complex , you need to set the upper...

Re: LiFePo4 for DUMMIES

In theory yes, in practice no, bear in mind that Lifepo4 has particular jumper requirements because of the very high short circuit current that can be generated

Re: LiFePo4 for DUMMIES

Yes on the face of it, it would seem to be capable of that. sterling has developed some high power DC to DC technology and they are seemingly making quite a few products from it.

Re: LiFePo4 for DUMMIES

Have a close read of the instruction leaflet. It's seems a little simplistic to me. All it is is a voltage convertor. It doesn't provide any cell monitoring or proper LVC or HVC protection.

I...
