Simple Battery Management Board (SBM)
The easiest way to protect a lithium battery pack. The SBM board manages a pack of cells and disconnects the load under any unfavourable circumstances: cell over voltage, cell undervoltage.
SBM16/60 - the management board for 16 LFP cells (48V) with power up to 60A. (photo) Check the PDF with technical specifications for SBM16/60. For higher loads you need to use a DC contactor to be managed by the SBM board. This drawing shows the DC contactor installation.
