BATMon Kickstarter - Add Smart Battery monitoring to a non-smart battery

@echogee hope you get funded. I backed your project since I believe it is an important part of an easy to use system.

  • The battery capacities are currently set on EEPROM in factory, but will use the I2C interface to update that for ship rev.
  • It monitors the charge flowing back.

By what means? What will be setting that?

We are making a goal to move towards an OpenSource(GPLv3) firmware for BatMon if we get funded AND have enough wellwishers/supporters to hit either of the milestones below:

  1. Atleast 300 total Kickstarter backers of any reward
  2. $10000 total raised on Kickstarter

The project will live as a healthy opensource project if there are enough supporters. If everyone on this page ask 15 friends to support, weā€™ll be reach the goal.

Ordered my XT90-I connectors.
Starting to collect the bits

47

@echogee may i suggest you post some demo video of it in action with arducopter.

An arduino with I2C interface can change the Battery settings etc. Any uC with I2C can in theory do this, but Arduino is what weā€™ll use to program for the ship version

49

Consider looking at ArduPilotā€™s Lua scripting interface: you might be able to provide a script that would allow users to update those settings themselves

Well dang I just got a notification that they didnā€™t reach their funding goal. I guess that means this project is DOA. Thats a shame I was looking forward to incorporating this into my battery build.

Dang even my XT90-i connectors just showed up today.

You can look at my github, there you can build one yourself.


Just save your values into to variables.
I recommend an Arduino Pro Micro, since it has 8 analog ports (6 cells, temperature and current) + I2C.
I plan to design a board and release the full code, but right now Iā€™m just to lazy.

We are sad the campaign didnā€™t get funded. But we promise the XT90 connector wouldnā€™t go waste :slight_smile:
We are seeing how to get this off the ground.

For anyone interested in BatMon, it will be a great help if you fill this quick survey to understand your battery cell and current needs: https://forms.gle/FFhWD4kAhxRCv6rK9
I promise itā€™ll take not more than 1-2 minutes

Did the survey.
Fingers crossed you can get the project going.

Any news on the Batmon front

@rickyg32 We have a hardware unit for 6-10 cells and the software will be opensourced.
To use the unit, you would require access to

  1. AVR dragon or another JTAG interface.
  2. Basic electronic workbench for programming the Batmon

Iā€™ll reach out to people who have filled up https://forms.gle/FFhWD4kAhxRCv6rK9 . I case I missed you, please PM.
