  • Using top quality (A-level) protective integrated circuit IC, from Seiko of Japan. The IC itself has power a balancing function. The circuit is simple and reliable
  • Strong load ability, high constant discharge current, using high voltage tolerant and ultra low resistance power MOSFETs. Daly's extra large heat sinks and sealed thermal coating greatly assist cooling
  • Voltage detection for each cell so each cell will be protected from over charge or over discharge. The over current and short circuit protection function is a built-in feature to preserve the life of both the BMS and cells.
  • Temperature protection during charging and discharging
  • Extremely low power consumption. The consumption of the whole device is between 50 - 600uA depending on the model without Bluetooth. While the Bluetooth module is on, 15mA.
  • The PCB uses anti-corrosion, high water resistant, high impedance ESD conformal coating
  • Program via UART to PC cord or let Solar 4 RVs know your battery capacity and we can program the unit for you
  • Look up SMART BMS by DalyBMS on the Android Play Store or iOS App Store
