What are the features of the assembly and operation of Lithium-Titanate batteries (MpCO)?

Batteries

Hello.

Question about batteries. In particular Lithium-Titanate cells.
I found such type of elements as Microvast MpCO in a "pancake" case ( link ). The dimensions of the case are just perfect for the project. I wanted to know:

How good are these cells compared to the standard "lithium-ion" (IRC 18650 format, etc.)? Well, they are actually very good. And the operating temperature (especially negative), and the charge-discharge currents, etc. To what extent does this correspond to reality?

How safe are they to use (Do they burn like IRC Lithium-Ions? Do not burn at all? Hiss? What do they do if they are pierced with a nail at full charge?). How safe is such a "soft" case? Does he need a soft case? Or you can just wrap it with tape, and stuff it more tightly into the box so that it doesn’t hang out there, and that’s enough?

Does it get hot when charging? Considering that it can be charged with currents of 2C, with the planned battery it will be 40-50 amperes, will it not light up during such charging?

Is the usual BMSka 2.7-4.25 suitable for them ( example available )? In terms of performance characteristics, it’s suitable, but these Chinese boards are full of pitfalls, so the question is for those who know and practice, is it possible to take any that corresponds to the performance characteristics, or are there any nuances?

Thank you.
