Default Tired of everyone "Making a Mystery" out of the I2C protocol and the battery...

Hey all...

I've been on the sidelines for a few years... but with the rise of the various e-Scooters and NineBot/Segway starting to ramp down the balancing scooter business in favor of the smaller "Mini Segway" the time for closed-source solutions is coming to an end.

Felix, I know that you've put a lot of work into your battery analyzer, and I think it's going to be a great one-stop device for people who want something that "just works!"

The Segway original, i2, x2 market is small, and we need more general purpose and inexpensive tools to let people quickly diagnose their cells, and to let people build compatible cells using Li-Fe batteries ( and if they are so inclined, the more dangerous but more power dense Li-Ion cobalt cells. )

For people who are curious about the I2C protocols and how to communicate with the battery for DIY solutions, or to make projects on the Arduino and with a Raspberry Pi board... I'm going to release an open-source project on GitHub and a set of libraries to talk to the cells along with a BOM and Gerber files sometime in mid to late January.

Since I likewise independently spent the time to reverse engineer the battery I can choose how to proceed with what I've learned. I choose to give it away with an open source license and open source hardware to let others build on that knowledge.

Good luck! See you all in 2019. Code will be uploaded to:

Thank you!! And I, for one, canít wait to see the bits. Ready to have some fun with this!

It will be interesting to see what other inventors come up with by using the information that Martin releases.

Also, I am really hoping that Felix is able to bring his ready-to-use device to market soon, because an analyser that can be used in the field will be most useful.

Hi,
The tool was ready to be sold starting from May 2018.
I sold some units, also have on stock, booth versions,
Quick Reader, and the Advanced Capacity Tester that includes forced voltages equalizer, Battery health, and internal resistance measurement.
Now iím learning the Microsoft visual studio to create PC application to
make a nice window to monitor on pc or laptop same data as on tool display,
but more friendly and more display data, also nice graphics and printout
paper as an official data regarding individual tested capacity.
This weekend i will post on youtube the new update of the tool.
Cheers M8ís!

This is the analyser, a stand allone self powered unit, Best for use on open field,
whre no power supply available:

https://www.olx.ro/oferta/testere-ba...j-IDbIlAh.html

The advanced tool ballance battery and get it back to green-flash led where the
default segway charger returns red light ic cannot revive one or more cells with voltage
under expected voltage, even revivable and not defective cell(s).
My tool help and insist to revive to 3,42V sofar with big rate of success.

by the way, dear martinbogo,
The serial nr of battery displayed at the bottom of your printscreen is in my
opinion simply arbitrary example, look:
C01071600611 means,
Date of birth january 7’th year 2016 in that date batt nr 611 out of the
producției line.

-batts of 2016 all are at least Ref.AJ or higher.
-611 is over daily capacity.

Maybe is only a simulation, or your tool not retrive correct data from BCM.

I can offer base-stone info and valuable know-how info of my i2c battery bcm diagnosys project, in exchange of CU schematics, or basic drowings of CU board.
Best!

Hi, any update? I have a 14S3P pack that's dropped to 1.18v per cell or some cells could be dead, (reads 16.48v total) do you think it's revivable ?
