Daly BMS Info

Daly BMS Activation Procedure -Video - Use battery jumper cables to go from B- to P- to bypass BMS when starting first time or restarting. May be necessary to set Dally BMS max and min v/cell to wide range to get it to charge and start to balance the first time. 

Liston Lifepo4 Battery Cells values for Daly BMS

Broadened Horizons' 48v Battery 270ah 14.7kwh 

  • Max Charge Voltage 57v (3.5 v/cell)
    • maximum cell voltage of 3.65 v/cell  > 0°C (or 2.0 v/cell > -36°C to 0°C)
  • Growatt Undervoltage Cut Off Point 48v (3 v/cell) > 0°C
    • 54.4v Resting Voltage (or trickle setting, though Li batteries should not be trickle charged)
  • BMS “Sum volt low protect” 21v (26.25 v/cell) > 0°C (or 2.0 v/cell > -36°C to 0°C)
    • BMS minimum cell voltage of 2.5 v/cell
      > 0°C (or 2.0 v/cell > -36°C to 0°C)
    • Max voltage deviation between cells 0.8v (default)

*Note from Mark* If battery deactivates to protect itself more frequently than is acceptable, over time it may be necessary to increase maximum cell voltage and decrease minimum cell voltage to account for deviations between cells with wear and tear and avoid complete battery disconnect. Or instead increase entire battery minimum cutoff voltage for example to 41.6 V and maximum charge voltage to 56.4v to avoid damaging individual cells)

How to manage lithium battery remotely?

 1. After the BMS is connected to the WiFi module, use the mobile APP to connect the WiFi module to the router and complete the network distribution.

 2. After the connection between the WiFi module and the router is completed, the BMS data is uploaded to the cloud server through the WiFi signal.

 3. You can remotely manage the lithium battery by logging into the Lithium Cloud on your computer or using the APP on your mobile phone.

How Daly BMS balances your cells and ... actually works!

Cell Compression Only Makes Sense at 1st Cycle Test in Factory

Kalinda Life of Lifepo4 Batteries is 5 to 15 years. Compression could make sense in high charge/discharge rate situations like electric vehicles. Gaps for heat exhaustion affects battery life more.
