Description
DALY Smart BMS 4S 12V 250A LiFePo4 with Bluetooth dongle with cooling fan.
DALYBT 4S LFP 250AWF
Introduction about this BMS:
This bms is especially for 4S Bluetooth or smart fixed configurations. Basically it can also be used for any other lithium technologies even if LiFePo4, Lithium Ion, LiPo and Lithium Metal by changing internal parameters after connecting to Bluetooth App or computer. Most important that it is strictly for 4S battery packs only. As a result, that they cannot be used for any other battery pack Configurations.
In the same way all Parameters can be changed Via Bluetooth App or UART USB Connection with PC Monitoring Program .Default setting inside BMS are for LiFePo4 batteries.
Over charge and over discharge protection:
The LiFePo4 battery pack will stop charge after the single cell voltage reaches 3.7V and stop discharge when its voltage reaches 2.5V.
Temperature Protection:
- In high temperatures the bms ranges from 70℃ discharging battery protection.
- Meanwhile in low temperatures the bms ranges up to -20℃ battery protection.
Short circuit protection:
When there is a defect or damage to the circuit at same time the bms will shut down the whole Battery.
Certifications Approved:
ISO/ FCC/ RoHS/ PSE and CE APPROVED
Applications:
Solar and RV, Electric bikes and Skateboard including camping boats and Power tools, Lawn moving and household energy storage systems etc.
What you will get:
- 4S Smart LiFePo4 250A rated voltage with 12V BMS with cooling fan
- Balanced wire sense cable (5 Wire sense cable with connector)
- Thermocouple
- USB-UART Cable
- Bluetooth dongle
- Instruction Manual
Conclusion:
Most important that it is only a waterproof bms available in lithium industry.
This BMS is also for all kinds of lithium-ion cells including 18650 ,21700,36500 cylindrical cells and prismatic cells.
