Description
DALY BMS 4S 12V 40A Lithium ion with Balance leads.
DALY 4S Li-ion 40A
Introduction about this BMS:
This is a 4S fixed configuration basically it cannot be used for any other battery pack configurations. Because it is only a Lithium ion battery management system only. As a result that they cannot be used for LiFePo4 and Li-Metal or LTO batteries. It is strictly for Li-Ion battery packs only.
Over charge and over discharge protection:
The Li-ion battery pack will stop charge after the cell voltage reaches 4.25V and stop discharge when its voltage reaches 3V.
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 Li-ion 40A rated voltage with 12V BMS
- Balanced wire sense cable (5 Wire sense cable with connector)
- 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.
