    Those were "Lithium Ion" batteries in the Dreamliner, not LiFePO4. Again, different chemistry.

    These 280Ah cells are popular with the DIY solar folks. If my home-made 200Ah lifepo4 pack wasn't working so well (about 2 years old, and cost about $800 then) I'd go that route. Probably 2 sets of 4 and 2 BMSes (one each set of 4) for redundancy. I'm using a 125A DALY BMS now and it works fine but does not have a low temp cutoff (batteries are inside the trailer, so not too worried).

    If you're comfortable building a pack, I encourage anyone to do so. It's actually quite easy.

    Yes, 280 ah Prismatic LiFePo4 cells are popular cells for use in DIY Battery projects. However, I am not sure going the DIY Route, building your own battery pack, could compete with the $271 per 100ah cost I found in my research. Besides, I am not sure at $271 per 100ah it would be worth the effort of building your own battery when this battery is available already assembled.

    I also felt including a DIY battery project would skew the results of my research, I was looking for "Drop-in" replacements that could be compared (apples to apples) to the Battle Born Batteries.

    PS: I also did not include my own experience using the Tesla, Model S battery modules. I wanted to focus on the "Drop-in" battery options that would be available to most of the readers on this forum.

    Disassembly of each, Battle Born and "Cheap Litium Batteries" is the only certain way to show that there probably isn't much difference in the battery composition and architecture itself. The big concern is the Battery Monitoring System incorporated and the casing (packaging) of the battery. The Battle Born is well engineered and proven, the main reason they can offer a generous warranty period. There are others like Lion Energy or Renogy. This isn't a promotion but a caution to look beyond.
    I could have easily gotten locally sourced LiFePO4 batteries assembled at a discount to the Lion Energy batteries I have.

    I consider Life Blue batteries the "Gold Standard" not Battle Born. They also have Bluetooth capabilities.

    Actually, there is, in that case. Battle Born batteries don't use prismatic cells, they use cylindrical. The BMS is not anything special, though.

    What I'd want to see in the case of these random super cheap Chinese battery packs is the quality of the wiring inside, as well as the BMS, etc. There are some that have been torn down and look pretty good, but some of the really cheap ones are trash. SOK is good.

    I sat in a workshop given by NYFD on Lithium Ion battery fires and take it very seriously if one catches on fire. The smoke is incredibly toxic and contains heavy metals and depending on the size you will play hell trying to put the fire out and will NOT be able to clean the area once contaminated.

    One thing to consider is that LiFePO4 batteries are a significantly lower fire hazard than the typical lithium ion batteries most people are familiar with (laptop, smartphones, etc).

    I agree with rootusrootus, LiFePo4, Lithium Iron Phosphate, batteries are safer than Lithium Ion batteries. LiFePo4 use a completely different and inherently safer battery chemistry.

    To be clear, all of the batteries listed in the spreadsheet and mentioned in the original post are LiFePo4 batteries and not the less thermally stable Lithium Ion batteries.

    Interestingly, I just read about a team of researchers at Penn State who have devised a method to charge LiFePo4 batteries very, very fast. Basically, what they do is heat the batteries up to 140 degrees (F) before charging them. This helps make the case that LiFePo4 batteries are a safer chemistry.

    The issue is the flooded ( no pun intended) market of cheap, poorly manufacture market of cells which may not be as bulletproof as Battle Born or Blue, but have great cheap costs.

    This coupled with the safety concerns with all lithium’s kept me in the safe Lead batteries
