@Lydie yes #JKBMS IF MONITORED regularly (can only do #bluetooth with app from http://www.enjpower.com/ #enjpower) can report bad cells as going way too high way to fast (4.3V???) #datasheed #eve #LiFePo4 https://www.battery-germany.de/wp-content/uploads/2022/02/LF280K-280Ah-Product-Specification-Version-B.pdf https://ultimate-solar.com/wp-content/uploads/2025/04/LifePo4-EVE-Datasheed-Datenblatt-LF280K-280Ah-Product-Specification-Version-B-prismatic-prismatisch.pdf this guy and others on #youtube keep promoting #eve #lifepo4 https://www.youtube.com/@Akkudoktor/videos
