Does anyone know where I can find the balance leads for all 86 cells? I am wanting to make my own DCFC and bms system using an externally connected orion2 bms.

I have just left the plugs out so that if it leaks again then it will just drain out

LiFePo4 cells are nominal 3.2v fully discharged at 2.5v and fully charged at 3.65v

Im building a pack that is the same pack voltage but the per cell voltage is different hence the need for a bms im hoping to make a separate battery can bus and send the car only one pack at a time or both if desired

i dont like the orig chemistry as much as LiFePo4 but i was thinking it wouldnt be a problem to mix the chemistries esp since im going to have a separate bms for the aux bat

i know that the different chemistries have different discharge/charge rates etc so im simply looking for what others thoughts are on mixing chemistries

i would like to know your opinion on an aux battery consisting of LiFePo4 cells but with a bms and same end voltage so the onboard charger would be able to charge it but the aux battery could also be charged separately with a second j1772 or dcfc connector as well

my idea is to put a second due in between the becm and the rest of the car to isolate the becm as to prevent any errors and yes the dc on the port would be hot all the time the car is on but since i have it under the hood and it also has a cover on it i am not concerned about that

Has anyone ever tried to control the battery's own contactors to implement dcfc? I'm trying to find a way to do that.

Any chance you can share the code? I am trying to install chademo on my 2013 ffe and am getting stalled by the code side of things. I know javascript like the back of my hand but not any c++ and so trying to modify code not written for the ffe is proving difficult. Pm me if you don't want it to...
