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.

What is the cost of something like this?

Hallo guys, hope you all are OK.
I've made a research and I foud some sells that can replace the old ones.
The capacity is higher but the dimensions of the cells are smaller than the original ones so there will be need some material to be added to stabilize the cells and make the battery safe to use.
Here three options:
a) 3.7V Prismatic Cell Grade A CATL 72Ah NCM Lithium ion Battery --> Dimensions: 148*29*103mm (I am not sure about the dimensions but the seller insists that the dimensions and capacity are correct)
Max Charge Current: 1C (not enough I thing)
Max Discharge Current: 4C (I think this is very good)

b) 3.7V Prismatic Cell 62.5Ah NCM Lithium ion Battery --> Dimensions: 148*27*97mm
Max Charge Current: 1C
Max Discharge Current: 5C

c) 3.7V Prismatic Cell Grade A 58Ah Lithium Ion Battery NCM --> Dimensions: 148*27*103mm
Max Charge Current: 2C
Max Discharge Current: 8C

It is very very important to choose Grade A cells.

Will the car be able to run with larger capacity cells without any modification?
Does anyone know if the vehicle can recognize and handle cells with a larger capacity than the original and thus a larger battery?
Can the BMS programming change so it can handle larger capacity cells?
