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. IBS cable part number: BMW 61219117877 Braille G30 lithium battery

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. |

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.

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 Link: https://www.ecstuning.com/b-braille-...ide&utm_term=1 --- 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 Last edited by srwhitman; 08-22-2021 at 01:26 PM.. |

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. |

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. Thanks, |

After reading your post I thought I would give the repair a go but got this far and got a little nervous. |

I have charged cells, there is 14V, but isolatong switch is still open and there is 0V on connectors. I don't want to burn the battery Edit: I have connected noco genius 10 to connectors and start charging in dead battery mode. After 1 minute isolating switch have closed. No need to put high voltage to the battery. Good luck with your batteries. My works again. Last edited by Doman; 07-28-2022 at 04:44 AM.. |
