After I had a few problems with the standard power module from 3DR and the ones from Hobbyking, like falling off resistors (overheated) and burned out BEC from voltage spikes, I finally designed my own PM modules. The sensor boards are compatible to Pixhawk, APM, Pixhawk lite, AUAV-X2, DroTek und CUAV Pixhack.
These modules are based on a true hall current sensor, so heat is no more an issue !!!
The sensors boards are able for continuous current of 100A for HS-100-V2 and 200A for HS-200-V2 (no time limit), the maximum over current is 1200A@25'C and 800A@85'C for 1 second.
Here some details:
The Sensor board is installed only into the positive main battery wire and the BEC should be installed as close as possible to the battery connector.
Quality control of the finished product:
To post here all the quality control during the production would be a very long story, so all I can say is, that it is carried out and recorded.
The final QC before the boards are shipped, is a setup with an FC (Pixhawk) and connected to MissionPlanner to check the calibration values for current and voltage measurement.
This final test result will be passed to the customer together with the order confirmation and shipment tracking number by e-mail.
REM: Which power module supplier out there actually use the PM to power up a real FC before shipment ?
So I hope everybody understands, that if I say "safety first"... then I mean it.
Why Hall sensor ?
Why only a few supplier use a true hall sensor for current measurement in an MR ?
Why output voltage to Pixhawk /APM is 5.35V and not 5.0V ?
Why the cable from UBEC to the sensor board is 4 pol ?
Why sensor board and UBEC are separated ?
Why is there an additional capacitor installed at the input of the UBEC ?
How can I get one of these boards ?
I bought one as well on the 16th, having problem with the tracking number.
It doesn't work where ever I try it at.
Did your tracking number actually work? Mine is not working.
I did contact Mr. Mauch and ask for him to check the number
but I think he thinks I am upset and does not want to answer my email.
It has been my experience that when that happens the item is lost or just plain not coming.
Just a few days ago I had this happen again from a buyer in China on ebay.
In fact it is a 1200mm heavy lift frame that I bought to use this item for.
Thanks for the information. I hope mine is not lost or something like that.
I am going to get another one if this one make it to me. I am planning on using it with pikhawk on 7s batteries.
Merry Christmas to you
and have a Great New Year.
First tests on a 100A module: everything is working fine. I made tests up to 70A continuous with no worries. Here a fast test for currents increments on 6S battery.
Got mine in the mail today.(12/30/15)
It is well crafted. Can't wait to use it.
If your having problems tracking the
your package it is because it is not a normal tracking number that is sent to you.
It is a registered mail tracking number. It is not intended for actually tracking the package,
You will have to sign for the package when you get it. The tracking number you get is mainly for Mr. Mauch's use not ours. So do not be upset (like I did) if you cannot track the package the normal way that you might be use to. You will get it, rest assured. And when you do, you will be happy.
Ok.. now someone tell me how to use 7s with this sensor.. The bec that comes with the sensor says 2 to 6s. I need to run 7s.
Ups... my record says you should got the 4-14S HYB-BEC together with your 200A sensor !
Is it possible I put there the wrong sticker on it... could you please post a picture of the BEC to clarify ?
No Sir you did nothing wrong.
My bad.... My Bec is for up to 14s..
I was reading on how to plug it all in and
when reading the specs on it in my old mind
I must have thought I was reading about the one that I have
when in fact I was not So I put foot in mouth for about the 50th time this month.
I hope there is a cure for foot-in-mouth disease
Hi Jim... thanks for the confirmation.
I was already checking all my remaining serial number stickers for any mismatch, but couldn't find one.
Best regards and Happy New Year,
I'd like to buy this sensor for my heavylifter!
Is calibration necessary? Because if I want to calibrate 200A sensor in MissionPlanner I will need 5kW power source. And that's a lot...
Hi Adam, calibration is not necessary for this sensor board. As I test each BEC / Sensor combination before I send them out to the customer. The test result and shipping details will be send via email afterwards to the customer.
So just setup the values for voltage and current reading as follow.
1. On the mission planner’s INITIAL SETUP | Optional Hardware | Battery Monitor screen set the “Sensor” to “Other”.
2. Enter the voltage divider from the final test result and press "TAB" or click out of the field. Then the "calculated battery voltage" should be within a few millivolt of the actual battery voltage.
3. Enter the "Amperes per volt" from the final test result (A/V) and press "TAB" or click out of the field.
That's all you need to do... have fun !
Perfect! That's all I need to know.
I will use 2x 6S 16000mAh... I'd like to monitor both batteries separately. My octo could consume up to 400A.
Do you know if it is possible to connect two battery monitors to Pixhawk?
Thank you! :)
