I am just bouncing around the edges of understanding at the depth of most electro-phils but after replacing my 2,  6 year old AGM batteries with a LiFePo4 battery I decided to reuse them and install them in my cabin with the old 90 watt portable panel and controller The two batteries weigh in at 55 pounds a piece and I am glad to have them out of the camper. With a box and a few USB plugs it is a good reuse for the batteries dwindling years of production. I hope one day they will still take them to recycle.

 

PS just remembered why I wanted to post ... this is an amazing compilation of links...if it is ckent323 who is 

is keeping up with this ...THANKS!

Ditto.  Very amazing resource!

Yes, I am trying to keep it reasonably current (pun intended).  

Glad some folks are finding it useful.

 

Best,

Its not really the ultimate battery thread if its limited to just Lithium and AGM.

Good point, Fuel Cell technology was missing too. 

So here it is:
 

https://www.fuelcell...uel-cell-works/

 

Other than burning coal and oil this thread now covers most portable electrical energy sources.  ;-)

 

FLA, AGM and LiFePO4 Battery (plus other battery chemistries) as well as fuel cells and portable nuclear batteries.

 

Hopefully this does not encourage the thread going long off topic as some people seem to find it a useful reference.  Would be a shame to spoil that.

 

Now back to your regular programming.

 

See page 1, post #2

So thanks Craig... this has been an incredibly valuable resource not only for its content but also that it is all in one place and a great time saver when searching an idea or explanation.

I sit now in my camper though it is not on the truck yet and marvel at my new battery set up. It could never have happened without this valuable website and those kind enough to share knowledge. Can’t wait for our next trip in a couple weeks to see how it all performs.

Lithium vs Lead Acid

Very interesting article. I'm still ruminating on the idea that I don't use enough of my batteries capacity. This is true, most of the time I'm using 10-15% a day but, I like having that extra capacity sitting there in case I do have a couple cloudy/stormy days. It'll be interesting to see if anything changes in the five years I expect to get out of my current batteries.

That was a great video. I like that guy, enthusiastic and...he knows his stuff and is able to explain it (even better). I have watched a number of his tutorials on the components of setting up the LiFePo4 batteries. Fortune would have it my AGM batteries were 8 years old and so that pushed me to just do the Rando battery build. I am so happy with the result and the benefits described in the video are reason enough. Weight ! So if anyone out there is on the fence and near battery replacement.... do it with the LiFePo4. It all fits in the battery box. Twice the juice.
