[SALE] Deligreen/DALY LiFePO4 SmartBMS: 12-48v 150-300A Cell Monitoring, Temperature Protection, Pack Management



Designed for use with LiFePO4 cells such as the EnerAmp series of LiFePO4 batteries or other similar raw cells.  A BMS can protect your batteries ensuring maximum lifespan and performance.

These BMS units have the following features:

  • Includes USB Monitoring & Programming Cable for customizing setpoints and extended status monitoring.
  • Over Voltage Protection: If any cell(s) in your pack exceeds a safe voltage, the BMS will stop charging current from passing through, but will allow loads to draw power from the BMS without needing to be manually reset.  The BMS will automatically reset when voltages fall back within a safe range allowing for charging.
  • Under Voltage Protection: If any cell cells(s) in your pack fall below a safe voltage, the BMS will stop power from being removed from your battery pack, while simultaneously allowing charge current to enter to bring the cells above the minimum safe voltage.
  • Over Current & Short Circuit Protection: If you accidently draw too much power from your batteries, the BMS will interrupt this current, preventing damage to your batteries.
  • Under Temperature Protection: LiFePO4 batteries cannot be charged below 0° C (32° F). This BMS will disable charging when temperatures are too low, and automatically re-enable charging when temperatures are back within safe limits.  Limits may be adjusted using USB Programming Cable.
  • Over Temperature Protection: This BMS will completely turn off if the temperature probe(s) detect temperatures in excess of 75° C (167°F), preventing damage to batteries in high-heat applications.
  • IP66 Rating: Acceptable to install this unit in locations where moisture may be present.
  • Models 250A and under feature a fan-free design; No moving parts to fail, or airflow path requirements.
  • Bluetooth connectivity to your smartphone, compatible with Android & iOS with use of Bluetooth Dongle (sold separately).

Note: This BMS has a built in passive balancer, capable of 30ma of balance current.  Before assembling your battery bank, we suggest manually top balancing, or utilizing an Active Cell Balancer instead.  If you are using low-quality or B-grade cells, the BMS will not provide enough balance current without the addition of an Active Cell Balancer.

If you have properly connected your BMS, but it will not activate, try the following:

  • Ensure the NTC probe is plugged in prior to inserting the balance harness.  If you need to unplug the NTC probe for any reason, you must unplug the balance harness and reinstall the NTC probe prior to reinstalling the balance harness.
  • Use a light board, or activation button to initialize the BMS.  Some chargers may not begin charging until it sees the battery, in which case the charger is not easily able to wake the BMS up.
