Drive battery replacement compatability

[Tarkain]

Hi, Im looking at replacing the 12kWh battery in my 2014 outlander. Does anyone know if the later 2018-2019 13.8kWh battery will fit, and work ie with the BMS?

I have the same question about my 2015 Outlander.
Did you finally find out?

The entire pack from newer MY is not direct bolt-in compatible as far as I know, but others have replaced the individual cells in the original pack for increased capacity, @vtechtuning did a 19.5kWh pack inside the OEM case using the OEM BMU/CMUs. There's not much detail I found online, but I think he made his own size-compatible bricks using cheap 18650 cells from China at the time. Here's the post he mentioned it in https://www.myoutlanderphev.com/threads/first-test-of-19-5-kwh-battery-in-phev.2777/ and he also has a YT channel but there's not much there now, I think some of the videos have been removed over time. https://www.youtube.com/@vtechtuning_eu/videos Production EVs can be modded like this, you can also put range extending packs in parallel with the OEM battery, most anyone familiar with DIY EV builds will have the basic knowledge on how to do that kind of thing; the trick with a parallel pack is finding a good place to put it, often on a trailer, one build was posted with a large steel box in the cargo area.

No to both questions.
Neither will directly fit neither the BMU will work with it.

Does anybody knows if the cells of 13,8kwh baterry fits to 12kwh battery?

Yes this can be done, I have done this with my own personal 2015 Outlander myself.

The packs are NOT a direct swap. The modules in both packs are identical size and voltage they just a little more capacity. So its just a case of swapping out the modules from 13.8kWh pack and putting them inside the case of the old pack. Some high voltage electrical knowledge is needed to do this as parts of both packs need to be dismantled to remove modules. 13.8kWh Outlander Pack supplied by Second Life EV Batteries in UK and Matt at Cedar Electric, in Worthing can do the work.

I not done any BMU reset and it still thinks it has a 12kWh pack. am seeing if it will learn new capacity itself. so far its been 4 months and 2300 miles.
