lithium titanate 18650

Anyone can comment about lithium titanate battery type if it really has 10k+ cycles even if discharged fully to 100%. I saw big batteries on youtube but no usable small size batteries.

That might be an exaggeration. Lithium titanate battery has its own wiki page which states:

Lithium-titanate cells also last for 3000 to 7000 charge cycles...

(which is impressive), but says nothing about being discharged to 0V, if that is what you mean by "100%."

Also note:

A disadvantage of lithium-titanate batteries is that they have a lower inherent voltage (2.4V), which leads to a lower specific energy (about 30–110 Wh/kg) than conventional lithium-ion battery technologies, which have an inherent voltage of 3.7V, although some lithium-titanate batteries are reported to have an energy density of up to 177 Wh/L

Yes they can last over 10000 cycles

and yes they do survive going to dead flat 0.00V.

But likely not the former with a set that routindly does the latter.

And very low energy density, I don't think made in the tiny round format most commonly used here.

Toshiba SCiB is the best known good quality example, not sure how good those beer can ones are.

5S makes a decent 12Vnom pack
