i'm continuing to remodel the whole thing in 3D and print it. 

Tinkercad is really easy to use, and you can get pretty fast results.

I have rebuilded the power system. my ina219 was not well connected and i2c informations was wrong. i've made a "shunt" near the battery, so i can calculate the percent left. 

I'm using 2x18650 samsung 25R. With a given temperature, volatge, and Ah its easy to calculate the percent left in real time :

Now i can get this information directly into the HTTP remote console : 

Next step is to build the communication bus. I'm thing about i2c, but CAN bus seems to be cool too. i've not decided yet.
