After finding myself without power too much, too fast, I bought myself a few Anton Bauer HC's.
But when placing two batteries my built-in diodes still took 0,7 volt off.
That's a lot!

I had a call with technician Robert Ploeg from Anton Bauer Netherlands.
He advised me to use a accesoire called a hot swap from Anton Bauer instead of diodes.
E.g. http://www.adorama.com/ABQRHSGM.html
It is using some kind of electrical gimmick so it only 'eats' 0,1 V.
This means that my rig will fly way longer with same batts!
WOW.

Better even: he send me one to dissasemble the electrical components so I could mod my steadicam.
This seems to me like heaven on earth for the power consumption problem!
Thanks guys from Anton Bauer Netherlands!

There might be a downside with other brands: it only works with AB's because of the 'intelligence' inside.



Will mod this week and will post details later.

Regards,

Mark de Vries

I know it's a long shot, but any news on this?

They're called hot-swap controllers. You can buy evaluation boards on sites like Digi-Key and mouser.

I used "ideal diode"

Try this: http://www.re-voltag...nicsID80V2.html

It says at the bottom of the page that they are sold out of the diode. Email is there to find out if this is still the case.

A properly speced diode will have a much lower voltage drop than the .6v mentioned here. Maybe not as low as an IC solution but not far off.
