    I need to put four 48V batteries in parallel, any suggestions what BMS I can use? I would strongly prefer if it didn't need ethernet to connect to each other. Thanks!

    Active balancer or not?

    I'm getting the following made by a Chinese manufacturer and I'm very much in two minds if I should get them to put a 5A active balancer in or not, what are your thoughts?

    What refund would you ask for?

    I ordered 32x 272Ah Lishen cells and after being told a number of times that they're grade A, I was not impressed when I received them.

    Electrolyte leaking?

    I'm being offered these Victpower 400Ah batteries for a very good price. However these white spots worry me slightly. Do you think they're leaking electrolyte or something more benign? That label behind also looks much darker than the other one at the bottom of the photo.
