First, have the battery LOAD TESTED. What you have described is one of the symptoms of a failed battery. If that''s not it, the next thing to check is a poor connection from the battery to one of its cables or a poor connection from one of those cables to their attached to your vehicle. Check those to ensure they are tight and corrosion free.
How To Test a Car Battery''s Voltage With a Multimeter
Never allow the Battery to fully discharge. Even when Model Y is not being driven, its Battery discharges very slowly to power the onboard electronics. The Battery can discharge at a rate of approximately 1% per day, though the discharge rate may vary depending on environmental factors (such as cold weather), vehicle configuration, and your selected …
The Tech states that If the Battery was replaced with a BMW OEM battery and properly coded to the vehicle he thinks that most if not all of the errors would go away and the they are "Low Voltage" related rather than actually requiring a repair.

There are few things more frustrating than discovering that your car won''t start because the battery is dead. A mechanic can measure the voltage in the battery, in order to determine whether it needs to be replaced. There are two ways to do this. Open circuit voltage test. This car battery test determines how fully charged your battery is.
low voltage problem but good alternator and battery?
The fluid should cover the top of the lead plates within the cell by nearly a quarter of an inch. Any cells with lower levels may be unable to hold a full charge and are weak cells within the battery. Top up the level with battery water. Once done, refit the vent caps and charge the battery. Leave the battery for 12 hours and check it again.
Removing a voltage cut-off is extremely foolish, because you should NEVER use a battery under voltage if you want the battery …

BU-903: How to Measure State-of-charge
1. Eliminate the possibility of BMS undervoltage protection. Measure the open-circuit voltage of the battery, and if it is lower than the values below, the battery is in a undervoltage protection state and refuses to charge: - 12V BAT (10V) - 24V BAT (20V) -----Possible Results----- Positive: Confirm that the battery is in undervoltage ...
This 40 volt Kobalt lawn mower battery had been running down after almost 4 years of use. What originally gave me 24 minutes of power was down to only 6 minu...
What You Need to Know About Car Battery Voltage
Car Battery Voltage After Resting. If you let your car rest for a few hours to a day and then test the voltage you''ll notice one of two scenarios: Your battery is still above 12 V. The system appears to be functioning properly. The battery is holding a charge. And the system isn''t bleeding voltage. Your battery dipped below 12 V. There''s ...

The battery layout is 4 rows of 8 batteries. The batteries themselves are one of the biggest li-ion batteries I''ve seen. ~6in high x 1in diameter I would guess the large cluster of white wires at the top of the BMS are voltages for each cell …
Occasionally remove the battery from the circuit and test the battery voltage as described above until the voltage per cell drops to one. Calculate how long it took (in minutes) for the battery to discharge. Multiply the time by the current (in milliamperes) and divide the result by 60 to get the battery capacity in milliampere-hours (mAh).

O ne reason why alternators have a high failure rate is because they''re always working under a load. Generating electricity to recharge the battery, run the fuel pump, injectors and ignition system while powering all of the vehicle''s lights and electrical accessories places a substantial load on the alternator that generates a lot of internal heat.
Contact QuietKat''s customer support for guidance on battery replacement or repair. 5. Inspect Battery Health: If the battery voltage is within the correct range but still triggering the error, the battery itself might be aging or damaged.
