Daly Smart LiFePO4/Lithium 4 Cells (4S) 12V(12.8V) 250A BMS - Bluetooth & Balancing

Includes:

  • 1m long balance cables (5 pin) factory crimped with M6 lugs
  • Extra long black P- cable with M10 lug for easy attachement straight to the shunt
  • Blue B- cable with M6 lug
  • New Bluetooth module with Wake-Up Button
  • Temperature sensor (NTC)
  • Video Instruction Guide by QR Code - (It is mandatory this instructional video is watched!)
    • If any cables are incorrect the unit will be irreparably destroyed, the video instruction guide demonstates how to test this BEFORE connecting the plugs into the BMS

This version of the Daly may not have the lightboard slot, if you require one with a lightboard slot please contact us.

The 4S 250A SMART BMS is for LiFePO4 cells only.  You must use 4 cells in series and they must be LiFePO4. This BMS is ideal for a 3000VA inverter.

Features:

  • 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.
  • 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
    • Monitor state of charge
    • Current in/out
    • Power in/out
    • Temperature
    • Charge/discharge MOSFETs open/closed
    • If balancing
    • Individual cell voltages, overall voltage, maximum cell voltage, minimum cell voltage, differential voltage
