    Battery defect for IT brainstorming BMS_u029 - P85 MS 2013

    Vent valve is on the top of battery and a/c drain line is droping water close to this valve. Tesla's most stupid idea. In Reman packs this valve is removed.

    Battery defect for IT brainstorming BMS_u029 - P85 MS 2013

    This is mostly by short AC drain line. A/c condense water going directly on top of battery in early models. I strongly recomend to install 1031034-00-A and check umbrella valve.

    Roadster 3.0

    Here is brand new 3.0b pack charged to 99% in range mode. For those who thinks 3.0b packs are different... Still charge up to 4.35v like old LG cells from 3.0a pack. It doesn't sounds good.

    Roadster 3.0

    Absolutly nothing!!! Cell design is bad. They are charging up to 4.35v and this is causing quick degradation.

    Roadster 3.0

    So from your screen you have defo 3.0 pack. LRVoltage showing 4.3v which means you have LG cells which are charging up to 4.35v. So this "new" 3.0 battery has same cells configuration like old one. I assume range issue is because pack is not new - just remarketed. Is not possible to have old...

    New Roadster 4.0 Battery developement with Model S cells

    Hello, please respect that I will not explain here our know-how for some reasons. Biggest Tesla's problem to use model S cells was that model S cells have bigger diameter and are higher and are not fitting Roadster sheet.

    New Roadster 4.0 Battery developement with Model S cells

    Charging will still remain the same. CCS is a good point, but not so important now as the new battery.
