Looking for help!
I have a Drok regulator and an 11.2v 5200mah LiPo battery to power my EZB. My EZB keeps telling me my battery is low when I have the battery passing through the Drok at 7v. The problem is that the amps are not pulling through the Drok enough to juice the EZB. The EZB is only receiving .18ah. When I plug my smaller 7.4v LiPo at 1300mah directly into the EZB I am not having any issues. I'm trying to avoid multiple power sources in my project.
Is there something I am missing?
This is the Drok I'm running...
Thank you so much for any help!
Upgrade to ARC Pro

I think your thinking process is a little off on how the power gets to the EZB. The Amps don't pull the "juice" through to the EZB. The load you're trying to power pulls whatever amps it needs regardless. The only things that will stop enough amperage needed by the loading device is system failure or restriction. If your conductors are too small or too long of a distance, if your equipment is underrated for the amount of amperage the loading device is drawing, bad connections or a current limiting device (either in line or installed in a device). If any of these except / including the current limiting device is underrated or bad you'll get heat, melting, exploding or even no current draw. In the case of the current limiting device these are sometimes adjustable. I took a quick look at your second link and it mentions Current calibration. I'd start here.
What kind of motor or servo are you trying to power? How many amps will it pull at peak power?
Also there is a section on the EZB's web page that will disable this low battery warning. In ARC's connection tool there is a section where you can lower or raise the voltage where you will get this warning. Although I don't recommend it you can adjust the voltage up a touch on your DORK and overvolt the servo above 7 vdc (if that's the top recommended voltage of your motor or servo).
Do you have any suggestions for a better set up? Ultimately, I am powering two EZBs with a full load of servos and actuators. I would like to wire two of the 11,2v 5200mah LiPos in parallel. I can't tell you how much I appreciate your reply.
Others have been able to avoid EZB brownouts caused by amperage draw of the loading device by placing super caps on the EZB. There's a couple threads on this if you do a search.
Did you see my Edit above?
if you use Lipo Batteries in parallel don't use different C ratings.
The Drok you mentioned can't provide more than 4.5 - 5A.
Is not enough if you have a lot of servos and actuators, so wiring 2 x 5A Lipos in parallel does not make a difference.
you will need something like this (25A):
my guess is switching, specs: efficiency>85%, Non-isolated
I have one in my wish list, if i get one i'll open to check the inside.
If you would ever like to chat more in depth, I can be reached at firstname.lastname@example.org or through my site www.motusindustries.com
I’ve had R2 running around for over a year now and have been increasing my EZ Script knowledge with every mistake. lol
Anyway, thank you for all your support specifically around the kangaroox2. I was able to get it working because of your generosity with sharing code.
EDIT: Cool site! I'm going to spend some time looking it over. Thanks for sharing!
