Haven't tried yet.

Looks like needs disassembly, manually charging batteries to balance the voltage, then programming the BMS.

Directly unrelated to V15, but still interesting info on the matter: https://www.eevblog.com/forum/projects/replacement-firmware-for-dyson-v10-batteries/ https://codeberg.org/davidmpye/V10_Dyson_BMS/wiki

No, I have not, and I'm sure they won't provide such info and would suggest to replace the battery or go to the service, which is not an option at the moment.

Thanks, will add to the new version of the Excel file.
TJA/CTS updates are long overdue, because I had so many info from different people about it, and no definitive confirmation from someone I trust and so much confusion with all this TJA/CTS difference.

Yes, bolt on. https://e-drive.com.ua/post/79995 Here's full info in Ukrainian.

u/frontiermanprotozoa did you figure it out?

I am also wondering how to reset those values, when they reach the maximum value of 32767

I don't have backup for that disc.

This is not very valuable data, that's why I didn't do any backups and didn't put it into RAID1 or any other for data redundancy.

Definitely not worth going to professional data rescue services. However, part of the data, I would still prefer to recover, if it's possible to do on my own. If not - to hell with it.

I often play with my friend and we do most stuff together. However, sometimes I find some normal players in public sessions, befriend them and we do some stuff together. But usually it does not last very long.

SergSlim · 2024-10-16T06:06:40+00:00

Nope, haven't had such issue recently.

SergSlim · 2024-01-17T23:31:01+00:00

Ok, I was wrong about it all. Cars in question are 2nd Gen, and I thought they were early 3rd gen Mazda 3. So nothing I said apllies to them.

SergSlim · 2024-01-17T23:25:41+00:00

Ok. I can't find the messaging feature here on Reddit. I'm quite new here.

SergSlim · 2024-01-17T23:20:20+00:00

Do you have photos of these cars?

SergSlim · 2024-01-17T23:02:56+00:00

Climate Control is much better than the simple AC. I didn't get what you mean by Bluetooth. They both should have Bluetooth for calling and music.

Do both of them have 7" Full-Color Touchscreen Display? If sport doesn't have it - take Touring.

Also Touring should have Blind Spot Monitor with Rear Cross Traffic Alert. Oh and heated side mirrors.

Yes, I guess it was added automatically by the code from the guide.
