    Aha, ok. I will keep it low for now

    Need advice on BMS24

    Solid information, I am glad I started this post:) I now understand how the SOC determination works, I was under the impression that it was based on some high precision voltage measurements. So current counting probably means that I should never depower the BMS. In the mean time... I fried my...

    > I assume that SOC percentage is based on the measured voltage? The voltage of a certain SOC is of course also dependent on the current. I had assumed that not connecting the shunt would let the BMS think that the current was zero, which would be fine for my test setup, but because SOC display...

    > The slower the charger (lower current), the easier it is to overcharge, if not in danger of starting a fire, certainly reducing cycle lifespan. It was this that I could not place. I would expect that a lower current would raise the voltage more slowly, giving more time for the HVC to react...

    Need advice on BMS24

    Ok, that all is useful information that I can start working with. It seems I can keep using my existing power supply, but add an HVC, and maybe an LVC, and rely on balanced cells. I could use my BMS24 for balancing and keeping an eye on the individual cell voltages, because it seems to do that...

    Need advice on BMS24

    Thanks for both your answers. I bought the batteries from EvLithium in China. They shipped, but play dummy for requests on technical information or for a proper charger and BMS. I posted a request on a forum instead of contacting Chargery for their BMS because I had bad hopes on a response...

    Need advice on BMS24

    Hi, I am constructing a 16s 48V lifepo battery bank for powering a 10kW electromotor on my sailboat. The bank is currently in a test setup at home, please see attached pictures. Each of the 16 's' consists of 4 cells in parallel, so 64 individual cells total. I am (currently) charging with a...
