Best value for money protected 21700 cells?

I might need to get some protected 21700 cells.

(I recently ordered the Acebeam E70-AL.)

I already have these cells, but they are unprotected:

So, what's the best deal for relatively high drain (& high capacity) PROTECTED 21700 cells?

Why do you need protected cells — doesn’t the light have a low voltage protection

The E70 has become my favorite light. Not for all applications but its real sweet.

That is an easy query for my US battery database.

Unprotected cells may be too short for the Acebeam E70-AL.

Thanks for that!

Wow, protected 21700 cells are kinda pricey.

I think I would go with the Keeppower 21700 P2150R for $14 a piece.

(Those are supposed to be able to handle 15 amps of discharging.)
