Description DALY Smart BMS 20S 60V 80A LiFePo4 with Bluetooth dongle DALYBT 20S LFP 80A Introduction about this BMS: This bms is especially for 20S 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 20S 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: 20S Smart LiFePo4 80A rated voltage with 60V BMS Balanced wire sense cable (21 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.
