Ohmmu 12V Battery Feedback
- Thread starter LasVegas2019
- Start date
There's another thread with more responses. Link below. There is a mention of a new V3 battery that is already available.
Longer term Ohmmu experiences?
FWIW, I bought my Ohmmu battery around 11/21. Not a single issue with it until just about a week or so ago an annoying Passenger Restraint Fault which comes and goes occasionally. ( I decided to finally get a service reqeust in for it). When I was doing so, I went out to the car and...

Wish I had updates to share as a beta tester, but as I posted in the other thread I have received no real communication from them after experiencing the major code on 3/22. Other testers have received updates and apparently there’s a V3 battery version floating around, but I’m still with the beta battery with a module and receiving nothing from Ohmuu. I even get that it may be supply chain issues, but at least communicate with your testers after they experience an issue.
At this point, I’d rather be done with the company and would highly advise others to stay far away as well. I liked the idea of their product and offered to assist, and they sent me a broken experiment and left me completely unsupported. I think they are in wayyyy over their head and cannot recommend other customers to them.
The OP means their Tesla gave them an error on screen about a major issue with the 12V system. This is the code people are getting recently since Tesla changed their 12V management a few months ago, this person got theirs on 3/22.
It says something to the effect of "Electrical System is Unable to Support All Features - Shutting down features to conserve energy". Or "12v battery needs replacement, please contact service." It's a "VCFRONT" error in the exact error code.
I've recharged my battery for a few hours, did a hard reset and haven't received the error again for over 2 months and 3 updates.
I also left my car sitting for a week, which usually triggered the warning. Everything is working normally, so I don't know what the deal is anymore. I would assume the 12v testing by the car would happen at least once between 2 months, but so far so good

I installed the new version 3 battery on Saturday morning so far no issues. Only two trips so far 150 miles. Looks promising.
I received and installed the V3 battery yesterday afternoon and installed it. I did not drive yesterday. I left the car charging overnight and this morning I had the VCFRONT_a180 Electrical System Power Reduced error.
This was my exact experience with the V2 battery. Same error at times when I was not driving. I would never have caught in unless I went into the Notifications screen on the car.
I have a June 2020 M3 LR with the 2022.12.3.1 software.

I did a full reset and went for a short drive this morning. Let's see how it goes today. Thanks for the suggestion.
@Maytaur
Let us know how it went after the drive. Did the error resolve itself as it did for @AZAV8R ? It appears that maybe we need to do a drive of some distance (even a short one) to preclude the VCFRONT error as you mention you did the swap/install to V3 but didn’t drive and just let it sit overnight. I don’t know what that would do or how that would effect tripping the code or not but there may be a tie in there. Ohmmu didn’t mention anything to that effect on install/remedy instruction/direction on the new V3 but I’d definitely let them know the deets as referential Data Points.
You guys definitely have my curiosity up and as such I’ll make a point of trying to install my V3 today so we can get more info. Have to swap my winter/summer setup so maybe I’ll do that all today if I can work it in.

Well it took a lot longer but I did get a VCfront_a180 error this afternoon. Just one today so far. I'll report back tomorrow. The other odd thing is my car has not gone to sleep today since the full reset and drive from this morning. Not sure if that is related.
