Hallo,
die sogenannte Schutzschaltung bei 3,7V erklärt aber noch nicht die nur 9min. Laufzeit mit 2xLIR16340.
Wenn ich allerdings diesen Text von der Tiablo Seite lese,
dann weiß ich was los ist. Der Treiber ist eine Fehlkonstruktion.

"Remark:
Sorry for the delay of your order of MCE upgrade parts because Tiablo always want to offer most stable and high quality flashlights.
According to our weeks' testing, to ensure the reliability and make it stable, we decided to make changes to ACE's circuit as following:
1. ACE will be one level output. LED's working frequency is too low while the led working current is too high, 2.2A~2.5A, therefore, unable to get Infinite Brightness Setting or multi-functions.
2. Add protection for over discharging. As the current is 2.2A~2.5A, easily for 18650 to be over discharged. The new protection circuit will cut off itself when the voltage is lower than 3.7V to protect battery and flashlight.
3. Working voltage is 3.7~12v. Support 1 x 18650,2xCR123A, 2 x RCR123A, 2x18650, 4xCR123A (Remark: when use 1 x 18650, the highest current is 1.8A, so it is safe to use 1x 18650)
4. Max output 700lumen, runtime: 45minutes( 1pcs 3000mAh 18650) and 3 hours (2pcs 3000mAh 18650)"
