Are the 16340 batteries from Nextorch TA20 and acebeam TK16 interchangeable?

.. if not, what will not work?

Acebeam normal turbo mode with Nextorch TA20 16340?
Acebeam Eco Mode turbo with Nextorch TA20 16340?
Nextorch TA20 High Mode with Acebeam TK16 16340 until LVP kicks in? Have Nextorch TA20 a LVP?

I started a lil research:

Imax: TK16 ~ 4,5A | TA20 = ???
LVP: TK16 = 2,73V | TA20 = 2,63V

I found the keeppower RCR123AR (KP) and compared it against TK16 (AB) and TA20 (NT) battery:

Imax: KP = 5A | AB = 5A | NT = 5...6,3A
Umin: KP = 2,5V | AB = 2,75V | NT = ? (<2,63V)
Heights >> 33,7mm ... 34mm = should be fine
Protected: KP = yes | AB = no | NT = yes

Resources: zeroairorg and 1lumencom and seller sites from the above batteries

For having a charger near me I would like to use the keeppower and for traveling without a extra charger I would like to buy another Nextorch rechargeable batteries.

Knows anybody or finds the Imax from the TA20?
Same for the LVP from the TA20: who knows or finds the value?
Is it relevant wheather the batterie has a build in protection if used in the TK16?

I hope that this time a forum member gives answers.

no expert here, who can answer my questions?

In a review from the TK16 I found that the end voltage of the AB battery reaches 2,6V and because the TA20 stops working with voltage 2,62V it should be ok to use the AB batteries in the TA20.

Thanks for nothing.

I found in a Review of the TA20 that is has no low voltage protection, so it will drain unprotected batteries - like the ones from the Acebeam TK16 Osram - to death.

Summary: you can use the imr16340 from the TK16 and also gets some more outout, but don't leave the battery unused in it for a long time - the parasatic current would kill the battery.
