Optima redtop used to be a go to, they are not as good anymore and too expensive
battery testing good but is your alternator ? also with the tools you use to reset the bms you can also use it to look at the errer codes on both low speed and high speed can bus.
thats right them $10 cheapo scan tools at walmart dose not pick up or read all the errer codes.
