Just an update. I have been running this setup for a couple months now and have not had a single issue. No coding, just install the negative IBS cable and the battery itself.

BUT I will say I do not drive my car in the winter.

Trying an AGM

I bought an IBS from Hella online from Amazon.
I am going to try a Braille AGM B7548. https://braillebattery.com/products/...31acc932&_ss=r
However, I was told by a tech here that the battery wouldn't match and registration doesn't change the battery type so the car would cause the battery to prematurely drain.
I'm a bit worried about all this.

Techs don't have the ability to think outside the box and don't have access to the same programming resources we do. You'll be fine 👍

+ AGM Battery 70AH 760A there will be an issue? Its similar spec to Lio-ion OEM ?

Please advise. Thank you!

Hey @chetrickerman , i will try to revive ( save ) my Lio-ion battery... just ordered a Noco Genius 10 charger and willl try to force charge it to get into that 1v so it can start charging... if that doesnt work will resolve to AGM alternatives.

will keep you posted.

Cheers

Peter_2jz Did you try that? did it work?
I bought a charger that will wake up a Lithium battery and charge them. Its from CTEK. It has 7 LEDs - it got to the test LED and then started blinking on mine (basically says that the battery won't take a charge).

At this point, I'm really trying to figure out alternatives. Our battery stock says

770A
69AH
860 CCA

Now my question is - how does one read these specs. Maybe I'm cynical but I really wonder about the 69AH.

Options: Braille i48CX - as noted -
25 AH
but, right below that it says 75 LAH (Lithium Equivalent to Lead Acid Amp Hours). So I'm wondering if stock quote of 69AH is actually LAH

---
Another option: AntiGravity group 48

https://antigravitybatteries.com/pro...tive/ag-h6-rs/

It can be spec'd out with 60AH which seems close. Price is much cheaper than all these alternatives.

---

On the other hand, this site shows the stock battery at only about $150 more - considering how much these are, maybe its worth just getting that. https://www.bmwpartsdeal.com/parts-l...m/battery.html

Hello , i have just today 23.08 received my charger ,revived my battery using noco 10 genius
i will write a full post soon on how i did it.

I will also write a quick guide here

What i did was dis-asamble battery out of tray and hooked up charger directly to cells bypasing module, after they were charged 14v it still woud not unlock module, so i gave it force charge for 5 mins 20v it unlocked module and battery was saved!

Write me in my DM's i can call you via facetime and explain it to you

I decided to go with this: https://europeanautosource.com/antig...f8x-m3-m4.html

I spoke to EAS - they said someone there has an M4 and used this battery. Note that it actually includes the IBS which is cool (I had previously bought one so if I don't need that, I'll have an extra if anyone wants to get from me).

I ordered and it comes in next week. I won't be able to put in the car until that weekend so here's to "fingers crossed"!. I am really hopeful this works. total with shipping was $1034. Thats much cheaper than the BMW stock battery (who knows what brand) and even Braille.

Just need to register with Carly - hopefully that works too.

How did you tied town the battery? Is the battery moving at all?
Also are you a little concern with the lack of BMS from the Braille battery?

I am thinking the same set up, any info will be greatly appreciated.

You can put a group 48 AGM in it. Just make sure to code it accordingly and use the different battery cable. It works.

That said, I purchased the antigravity one in their labor day sale and am now using that one.
