Halcyon Focus 2 EO on Ammonite Battery

[JH_Saitz]

Hi all,
my first post - exciting!

As it says in the title: I am wondering whether I can run my Focus 2 head with EO cord on an Ammonite 14 battery. I've heard that the Focus 2 cannot be run on the Ammonite batteries as the batteries are not strong enough.

Has anybody got an experience with that setup or any technical thoughts on the matter?

Thanks
Jan

Have you tried contacting Halcyon?

I have, no response

I vaguely remember something about different voltages, but wasn't certain. I had a quick look online and Ammonite shows 10.95v whereas the Halcyon battery is 12.6v. Might work, but dimmer? Try it?

The Ammonite calls out 10.95v which is a 3s Li-Ion pack, same as the Halcyon. They're calling it out at nominal pack voltage vs Halcyon which calls out the full charge voltage at 12.6v. Technically Ammonite is more correct by using the nominal voltage vs. the full charge voltage so we can call the battery packs functionally identical from a voltage perspective.

The potential issue at least from quick glance at the product page is that the EO cord is limited to 200w, but is that a problem? Irritatingly Halcyon uses Lux which is absolutely useless. We can back into though, 5.2ah pack with a nominal voltage of 11v is 57.2w for the battery pack, and a 2.5hr burn time approximates 23w for average power consumption, round up for some losses and call it 30w. 30w is considerably lower than 200w for the output, so we don't have a power output issue. We don't have a pack voltage issue either since they're the same pack design.
Two potential issues, first is how the light head would react if you turned the output to low or medium but theoretically it should just shut itself off on low voltage. Second is if for whatever reason their "intelligent EO" design doesn't like the light head. It should just be checking for low resistance on the circuit which the LED drivers would provide to enable the EO cord, but that would be easy enough to verify at the surface.

Tbone knows far more about electrickery than me by the sound of things, listen to him!

Thank you all - esp tbone! Will give it a try and see what happens.
