I hooked my Enoid V4 BMS to a 32S LTO battery. I’m using VESC tool V6.02 and a 100/250 ESC. The VESC tool shows all the battery voltages correctly, but it doesn’t seem to want to Balance or Charge. There are 4 lights on the BMS plus the status light is blinking. The Charge Input Voltage is 86V and the Total Voltage is 78V. Input current is 0, SoC is 0, and SoH is 100%. I have the cell limits set to LTO type voltages, between 2.1 and 2.7 Volts. The chart showing cell voltage unfortunately is not scaled for LTO voltages, so 28 of the cells read 2.4V and don’t show up on the chart (min is 2.5V). 4 of the cells are at 2.6 Volts and show up, but they are blinking between red and green. The instructions for the BMS said to Disable the connected VESC BMS limit mode (SOC & OverTemp), but I don’t see where to do this.
My application is an electrically driven supercharger. I don’t want LiPo batteries in my car, so I’m using LTO.
BTW, I’m using V6.02 because I was having issues with the ESC. I sent the ESC back to Trampa and it came back working but with older firmware (V6.02) installed. They didn’t tell my why the newer version was causing issues.
