DALY BMS Li-ion 20S 72V 30A BMS Battery Management System for 18650 Lithium ion Battery Pack With Balance Protection

DL 20S 72V 30A PCB is used for 20 series Li-ion 72V battery pack. The main functions are: over charge protection, over discharge protection, over current protection, short-circuit protection, temperature protection etc. BMS manufactured by  high quality Mos and IC imported . Keep your battery long cycle service life time.

Introduction about this BMS: 

This is a 20S 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:

• 20S Li-ion 30A rated voltage with 72V BMS
• Balanced wire sense cable (17 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.

Advantages:

•  The 20S is equipped with a mechanical temperature sensor, which can well protect the battery such as overcharge and discharge resulting in temperature increasing, effectively improving the safety of battery use, and solving potential safety issue caused by thermal runaway of batteries.
• Use top quality (A-level) protective integrated circuit IC, from the solution of Seiko of Japan. IC itself has power balancing function. The circuit is simple and reliable.
• Strong load ability, constant discharge current 30A, use high voltage resistance, low inner resistance power Mosfet. The heat sink will greatly help cooling.
• Typical voltage detection for each cell. So each battery will be prevented over charged or over discharged. Over current and short circuit protection function is very reliable. Long time short circuit of the load won’t affect the PCB and the battery. Temperature protection during charging and discharging.
• Extreme low power consumption. The consumption of the whole device is less than 50uA.
• PCB use high anti-corrosion, high water resistance, high impedance ESD conformal Coating.
