That's the spirit! Jeez...

Check this thread, it has links to the best available technical information: viewtopic.php?t=5444



I'm hoping to the put the motor/gearbox/inverter in the back and the batteries in the front.

That is a really useful link though, thanks!

The battery is a large flat box. It is designed to go under the passenger compartment. In theory it is possible to reassemble the cells in a different shape, but you'll need to redesign the cooling system.


That's the plan!

That's interesting, not seen that before. Just checked and my i3 doesn't have the manual cutoff under the charge port door


What about the cut off under the bonnet panel??


I've replaced the 12v battery and fixed the pyro connection, reconnected the service cutoff in the front trunk to no avail. I think there might be another cutoff somewhere between the HV battery and the inverter/motor (Terminal 30??). I'm getting the car up on a lift so I can trace the power line soon.

I think I'll also need to clear all the crash codes etc from the crash module.

Do you have ISTA+? This is the software to read, understand and clear the codes.

Yes, have just downloaded it. Need a faster laptop to run it unfortunately so have one arriving tomorrow.

From what I've read and figured out, I'll need to bypass all the aribags and seatbelt sensors, clear the codes and then should be good to go.

Included inside the battery pack box is the safety box that contains contacts that when open, disconnect the battery pack from external wiring. I don't know whether the safety box contacts open automatically during a significant collision. However, I do recall reading somewhere that this safety box must be replaced after a collision. Whether what I read was about an i3 or some other EV, I can't recall. However, it might be worth looking into.

Here's to hoping it's just a software thing...

Thanks for this though, getting the car up on a ramp today so I can start tracing all the cables.
