Does anyone know what cell the Cyansky BL1834U battery uses internally, or otherwise its detailed specs?

Batteries and Chargers Rechargeable Batteries
16

So, I managed to obtain the missing data:

  • Recommended discharge current, in order to reach the 3400mAh nominal capacity: → 650mA
  • Recommended discharge cut-off voltage (ie, at what voltage the battery discharge should be stopped, again in order to reach the nominal capacity: → 2.5V
  • Recommended charge termination current (so the battery is maximally charged and will, during discharge, reach the nominal capacity): → 50mA

As for the “what cell underwrap” question, I’m pretty sure it’s a BAK N18650CP as the above parameters are exactly the same, except for the capacity which is 3350mAh (CyanSky may have rounded it up a little).

I hope this is useful to someone else – it sure is useful for me! :smiley:
