    isn't it 15 Amps per BMS board, so 45 Amps total, or 50 Amps each of the three parts?

  8. Avataaar/Circle Created with python_avatars Richard Sterne says:

    It would be nice if there was an RJ45 Ethernet network interface so the battery levels could be remotely monitored.

  9. Avataaar/Circle Created with python_avatars VikingSurvived says:

    I’ve seen some small charge controllers, you should make a charge control module for the towers.

  10. Avataaar/Circle Created with python_avatars 1959Berre says:

    Maybe an acoustic alarm (beeper) in case of malfunction could be included, since you can not keep your eyes on the system 24/7.

    Rather than using a display lcd what about using a single led that can change color ? Like red , blue and green , it can reduce cost and space so you could integrate it with your other board ,

  12. Avataaar/Circle Created with python_avatars RECLess says:

    So I've had a concern with your PCB system for quite some time now: How do you address serviceability? If I have a battery go out in the middle of a stack of 8 PCB's, is it a 2 hour process just to get to that one battery and replace it?

    I want to buy some these pcb thing you are doing how can I contact you?

    Hola amigo están muy buenos los videos y todos los proyectos que has echo todos están muy padres pero no sé si puedas ponerle traducción en subtítulos en español es que el traductor automático de YouTube no funciona muy bien con el inglés técnico

  15. Avataaar/Circle Created with python_avatars Omnipotent ! says:

    Beg my pardon, but that SOC is useless eye candy. I like the concept of the entire system though
