Bear in mind unless they changed, it's not LiFePO4, but Lion NMC - The latter do not last nearly as long, and have a greater (still not great) fire danger.
Watch for vendors who advertise "Lithium" as opposed to "LiFePO4" or "LFE" or "Lithium Iron" (not "Ion") batteries, if they don't mention Iron it's likely because they use the NMC form. NMC can charge faster and I think are more energy dense, so claims of super-fast charging also often point to the NMC variant, but personally for safety reasons alone I like LiFePO4. Not that NMC are all that likely to catch fire -- but if they do it's like a little explosion (google for video of battery tests to destruction). 2-4x the lifetime is just a bonus.
Linwood, I mean no offense but I think you are greatly overstating the fire danger for LiNiMnCoO2 (NMC). For the record:
1. NMC has a high energy density to weight ratio, nearly 2X that of LiFePO4, so it is used in applications where weight is a constraint. This includes electric cars (Tesla is one), ebikes, electric tools and most solar generators like those from Jackery. LiFePO4 is commonly used for Li batteries which look like car batteries. As such, their biggest use case is RVs and boats where weight is not so critical and number of cycles is more important.
2. With a thermal runaway temperature of 518 deg , LiFePO4 indeed has a higher temperature than the 410 deg F temperature of NMC. But, both are considered high and safe. It is some of the other Li chemistries that came to consumers much earlier that had the biggest fire risk and have thermal runnaway temperatures much, much lower. This has given Li batteries a bad name.
3. All of these NMC solar generators and stand alone LiFePO4 batteries come with an internal BMS which is there to protect the battery from unsafe operating conditions, including thermal runaway.
4. LiFePO4 batteries are rated for >2000 full discharge cycles. Some manufacturer's like Battleborn say 3000-5000 cycles. NMC is typically rated at only 500 full discharge cycles. However, think about what that means. You could run the Jackery down to zero state of charge (the BMS will cut off once the internal lithium cell voltage reaches the lower safe limit to avoid damage to the cells) 500 times and after that, you will still be able to get 70 - 80% of the original capacity out of the battery. If I spend 5 nights a month running the NMC supply down to empty that is 60 nights a year which gives me about 9 years of life at 100% capacity. If I don't need to run the generator all the way down to empty, I will get even more cycles. And then I still have a generator with a lot of juice left in it. I'd say that's pretty good and not necessarily a reason to shy away from NMC.
6. Solar generators with NMC cells are great if you want all the additional features that are built in. I use them and appreciate the built in pure sine wave inverter to supply power to my Dell XPS which must use its AC charge to be powered. I then re-charge the generator during the day with a simple solar panel since the solar charge controller is built into the generator. I like that the voltage output is regulated and stays fixed until the unit shuts down. I like that the dc and ac power ports are built in. I also like the USB charging ports for my phone. But, you pay ~$1 per Wh for all of this compared to ~$0.30 per Wh with a stand along LiFePO4 battery which I have also used. When using the LiFePO4 battery I have to carry an inverter for my laptop and a solar charge controller to recharge with the solar panels during the day. I like and use both depending upon the situation. Both are reasonable options for anyone needing power in the field.
I gave a talk on all of this at the NightFall Star Party last Nov. Anyone can download my presentation from my web site if interested. https://www.weebly.c...itor/main.php#/
