Hey Dani,

Congratulations on the great work and the photos. I assume you are charging the the 2nd pack with an external charger.

It looks to me if I understand you correctly that you are able to swap the BMS CAN signals from the internal and external pack and read the voltages from either pack. It's good to know that works. For the current I believe there are 2 current sensors somewhere I am not sure of the location.

I would guess that you are missing something that is generating the current value and putting it on the can bus for canion to pick up. I took a look at the diagrams I think you already know about this site:

I was not able to locate anything related to current sensing in there but I might have missed it. If the current sensor is working on the internal pack but not on the external one it might be some signal that is missing in the BMS connector or something missing downstream. If the CMU's also sense current and send it up to the BMU and maybe something is disconnected when you broke up the battery in sections. Did you see any current sensors in the battery ?

Maybe someone else on the forum knows where the current sensors are and how they send data.

What you are doing is really amazing. Please keep us up to date.

BTW

how does the car handle with the extra weight ? It looks like you are trying to get it as low as possible so it should be better then when sia47 did it.
