Description

DALY BMS 4S 12V 20A Lithium ion with balance leads.

DALY 4S Li-ion 20A

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 20A 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.
