the cheap ole original Ender 3. Filament is ASA, my favorite and perfect for functional parts.
Well it fits nicely on the battery. Now just need to finish soldering on up and test it on the first module.
so these batteries had a piggy-backed DC-DC converter. I believe that, or maybe the BMS, went bad and the service process was to just change out the entire assembly. So the cells are likely totally fine, I checked voltages when they arrived and all was good. i'll be cycling them in my truck as soon as i get my frankensteined Tesla/SmpBMS system finished.RetroZero wrote: βWed May 18, 2022 1:12 pm Were the batteries you bought from accident Vehicules?

Sorry for asking, re-reading your posts and found the answers. I can get my hands on a few faulty batteries. Don't know why they are faulty, so will get an icharger or something to check cell voltages before committing. I like your progress and will probably piggy back off lots of your work.
Hi, wonder if you Tested this BMS solution already and how it is looking
I've just finished wiring up the secondary module boards and am just waiting for more 4p Deutsch connectors (didn't plan well :\)
I agree!, though it's been a lot of work getting all battery modifications, soldering, and wring done.
thanks Retro!
So I did purchase the batteries not knowing why they were warrantied by Mercedes, so it was a little bit of a risk. But of the 16 batteries that I got, they were all at 3.86V/cell. So it had to be something with the BMS or DCDC that was part of the little assembly that went wrong. Granted, I haven't cycled any of them yet, so I could still yet find a problem.RetroZero wrote: βWed May 18, 2022 1:12 pm Were the batteries you bought from accident Vehicules?
