You'd probably need the boards or you'd have to be able to recreate the data stream the BMS expects to see.
And that is my big stumbling block.
Someday if ever feasible, I will upgrade my battery. The battery part and BMS part is no problem. However I'm a complete noob when it comes to canbus or knowing what the car expects from the battery modules.
It would be awesome if there was an easy way to just ditch the OEM battery and build a custom battery that just "plugs into" the FFE.
Look into Arduino products and shields for an easy learning route to sniffing the CAN. I started with my FFE using a Arduino Uno and a Sparkfun Can Bus Shield, but as soon as I ran the code, the car threw just about every warning it could generate (SSN, ABS, Low Tire Pressure, etc.). Luckily, I have Forscan to clear the errors, which were Can Bus related. Anyway, I think it may be due to not having the fuses for the traction control/ABS and pedestrian speaker installed
. I will however be trying again in me free time with fuses installed.
