LiFePO4 battery comparison - DIY vs Pre-made - which is better?

This is sort of a continuation on the LiFePO4 battery I built previously. I would like to share some of the things I found from DIY and buying ready made battery. Bear in mind the battery I DIY has been used for 12 months (in a car and in solar).
You can buy the battery here: shopee.com.my/...
Please support local brand (new start-up).

4:00 - you see, my alternator gives sometimes 14.9v. that means that this bat. bms will disconnect & the bat. won't charge. How much max V do you get from your alternator?

[@unkertech]

Max I have seen is 13.8v. After a while, it will always stabilize back at 13.3v when car is shutdown.
