Battery drain ruining batteries

Seems like the Cactus V6 units randomly drain the battery power when the units are switched off. Not always, but sometimes. Pity, as I now have two sets of ruined Eneloops.

Would be nice to get a statement from Cactus regarding this issue, maybe beyond the "your unit must be faulty please send it back" type of comment.

Nice triggers, sometimes a bit of a pain to get set up and working properly, but this battery drain issue is not nice. I think after losing two sets of Eneloops I will now hopefully remember to remove them in future when I do use the Cactus triggers...


  • Yeah, it is a bummer that the V6 drains the batteries, even when switched off.

    It is only a small amount, but enough to warrant opening the battery compartment when not using the units.

    I don't think your units are faulty. Mine do it as well and Cactus have confirmed somewhere that this is normal.

    Hopefully, a future model will feature a hard "OFF" switch, just like the one featured on the RF60.

    P.S.: I never lost Eneloops to the V6 draining issue. Yours must have been almost depleted and then left in the V6 for a long time to receive actual damage.

    Perhaps one of your units is indeed defective and draws an extraordinary amount of current, even when switched off?

    If you have a digital ampere-meter, perhaps you can measure all your V6 units -- just replace the function of the battery door with your ampere-meter -- and see whether they differ in the "OFF"-current they are drawing.

    The normal amount should probably not kill any Eneloops, but if you have a defective unit, it may be an explanation.

    Not that I'm happy with the normal amount of current being drawn -- it really should be 0A -- but perhaps a defect would explain your experience.
  • Yes please remove them, as we did mentioned:

    "Switch off the transceiver and remove  batteries during storage."

    Thanks for your understanding but to let you know R&D already knows about this and we will continuously improve our products for a better user experience.

    To help us better help you, always state the exact firmware version installed on your Cactus device(s), such as: "1.1.013", "FUJ.1.002", "v.103".

    For the time being, Cactus V6 (MK1) running on firmware version 2.1.001 can be triggered by a V6 II (MK2) running on Multi-brand HSS firmware (e.g. 1.1.013) and not by X-TTL firmware versions: PEN.A.001 and OLY.A.001.  No schedule has been released yet. 

    Cactus RF60X / RF60 Firmware versions A01 and A02 currently ONLY works with PEN.A.001 and OLY.A.001.  Other "A" version of X-TTL firmware will be released soon. For both Multi-brand HSS and X-TTL firmware versions (FUJ, SIG, SON), install firmware version 103 / 205 on your RF60X / RF60.

    Cactus RF60 is now an off-camera TTL flash with firmware version 205 or later!

    Metz M400 (for Fujifilm) is now supported on the Cactus V6 II (HSS and TTL).

  • Thanks.

    Class A - Eneloop battery technology doesn't like being totally drained flat. 
  • I also have recently "killed" 8 Eneloop batteries leaving them in my V6 triggers with the power turned off!! Too bad I didn't read this first!!!
