Hi!
Yeah, the battery heater is not enabled. In the repair manuals they state they start up at -20 C and stop at -10 C. And with them being hard to fit for most builds i never enabled the functionality

Hi!
The Resolve controller and leaf BMS have can termination. Unfortunately some older OLEDs also have can termination. but this is removed in newer versions. And it has not caused any issues for any customers as far as I know. So a tap in from the wires between the controller to the BMS is best.

Hello @matthewjstead and @KoduEV sorry for the late reply. Using other cell types with the leaf bms is not something I have done and can not really recommend. I know there are companies in China and on Alibaba that offer Leaf replacement packs with other cell types. I have heard from customers who have had success with that but can't really recommend it since I haven't tested it myself and don't know how it works

I just went in on the forum and saw a bunch of new messages! Unfortunately a little later than I would have liked to. But I will check on the forum more often in the future. If you want to get my attention and make it easy for me to see the post just @isak me and I'll get a notification

Hi @Emanuel !
If the wheels are turning now I believe you unfortunately got a bad display (we always test them before shipment but we have had a batch of bad OLEDs recently) Could you please reach out to us via email and I'll send you an new one. info@resolve-ev.com

Hi!
I have attached the dbc file that the OLED display uses to show all the states. Those are really the only signals that I have added to the can network. Otherwise as you mentioned you can find all the Leaf canbus messages from dala here: https://github.com/dalathegreat/leaf_can_bus_messages

Let me know if there is something else you want to know!

You should wire it so that it can turn on during charging, but it won't turn on during chademo charging since no power converson happens then ( so no loss that heats up the PDM / OBC). So instead of wiring from ignition you should wire it directly to the 12V. However for most ev conversions the fan never turns on because not that much heat is generated either when driving or charging

No need to do a software update we install the latest versions on the Controllers before we ship them!

Looks great! Did you cut the gearbox in half?

Just be aware that torque is linear with gear ratio, so you will have 8x less torque at the wheels than the original leaf (assuming same size wheels). Does the spitfire rear diff have gear reduction?

Our forum is now live! This space is built for anyone working with Nissan Leaf components, EV conversions, custom vehicle builds or design concepts.

You can share full builds, ask technical questions, document progress, post design ideas, compare parts, and discuss solutions.

We will also provide customer support directly on the forum.

Over time we will add more features, if there is something we missed let us know.
