If they will not accept that 100's of manufacturers, countless experts in the field and users alike say "at 11.8V you're not going to get much more out of it and it'll be risky to try", then just convince them with the fact that at 11V there won't be much to get any more anyway. All the modules BMS act as a slave BMS and communicate with a master BMS via an isolation barrier, the master BMS communicates with the ECU and charger and controls the main contactors. How does one determine Lead-Acid battery end-of-life? If you leave your battery at this voltage range for a lengthy period of time, it will be badly harmed. Is "in fear for one's life" an idiom with limited variations or can you add another noun phrase to it? Think of it this way, Let's say your battery's voltage dropped to 10v and your circuit cutts off all load, as early as you cuttoff the load the voltage would jump back to 11v, the load would power on again, eventually your load would just keeps turning off/on repeatedly possibly causing more harm to the device you are powering. TESVOLT made it onto the final list of the 300 best companies in the country. Just be foolish enough to overly discharge your batteries and you will soon find out. The IEC 60038 standard, on the other hand, explicitly defines the limits: low voltage is up to 1000 V, medium voltage is 1000 V to 35 kV, and high voltage is more than 35 kV. Summarizing, the main points are these two: 1) Once a 12V LA battery is down to 10-11V, the voltage will plummet rapidly.
