I am going to ask very generally in the following context-
I am in a hobby where the limitation of batteries becomes more of weight than cost or size.
Cost would then be the next limiting factor but that can be extended far past weight.
Anyways, while having done some research here and there about LiFePO4 in terms of testing and the typical usability of cells whether it's cylindrical or prismatic, one thing tends to come up from every topic..
That is they keep failing or they do not last that long. Not the packs, but certain cells.
From where i come from, i drive cars with flooded battery that last 5-8yrs before it needs replacing.
In my current hobby, using AGM batteries that go through multiple owners lasting up to 10yrs with rarely any issues.
Then i go to research LiFePO4 and i can say Lithium by default to the public is a customizable hobby so human error can play a role in the outcome of packs.
But.. it seems that practically every custom pack has issues?
That doesn't sound good for lithium technology to me at all..
However, in my situation, i have an advantage if i am correct on this-
Most users who use lithium need it to longevity until the packs die. eBikes, EVs, drones, etc.
In my situation, i fully control the discharge value and time, So, i am "assuming" LiFePO4 would be great at controlling it's durational life rating.
I have products which will shut off loads 100% to prevent cells from being discharged too low.
Over-charging would be impossible as they would be auto-charged via alternator set lower than required voltage (and manually charged later).
Balancing would be done when manually charging.
So, in my situation, while i see many issues with lithium such as poor QC, few dead cells here n there, lower than rated specs, etc..
As long as i can control what i say above (because my packs are an auxiliary power source, not primary. When in use, they are constantly being actively monitored and protected) then i should continue continue to look into using LiFePO4, correct?
I will not be using any BMS or PCB protection because i can fully control and stop discharge and prevent overcharge from occurring. Active monitors are set in place when using much smaller loads and would be balanced manually.
