Description

DALY BMS 4S 12V 250A LiFePo4 with balance leads and cooling fan.

DALY 4S LFP 250AWF

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 iron phosphate battery management system only. As a result that they cannot be used for Li-Ion, Li-Metal or LTO batteries.It is strictly for LiFePo4 battery packs only.

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 LiFePo4 250A rated voltage with 12V BMS with cooling fan
  • 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.
