    Pack assembled but cell voltages all over the place

    Yes, I confirmed the BMS cell readings by using a good quality multimeter and they were accurate. However, as soon as I got the Victron hooked up and working, then within about 2 minutes of applying a decent load (around 1.5kw) then the cells all equalised. Since then they've all been almost...

    Pack assembled but cell voltages all over the place

    For the top balance, I connected all the cells in parallel and in a line. Imagine cell 1 being leftmost and cell 16 being rightmost. I then connected to the PSU the +ve from the leftmost cell (cell 1) and the -ve from the rightmost cell (cell 16). I'd heard that this was better than connecting...

    Pack assembled but cell voltages all over the place

    My first time building a pack, but after reading here for weeks. I've got a really odd problem.... So this is a 16 cell 48V unit. I top balanced all the cells by connecting all in parallel and charging at 3.65V until current dropped to zero. This looks weeks and weeks! Then I assembled into the...
