Customer Reviews
i have a nice memory of our meeting in Shenzhn with Deligreen Mandy and a beautiful impression of your growing company.We both are straightforward and honest people and this is the most important value,so i am sure we can

—— Angelo from Italy

I am sure we can happily work together we should easily find a way to do.Money are important but aren't the most important part.

—— Angelo from Italy

Deligreen is the partner that i have replied one for years. Some other suppliers change sales quickly but Deligreen not.

—— Bonnett from USA

i have used the batteries for 9 years from Deligreen. Amazing!

—— Phil, LA

COVID19 made something more difficult. we need the balancers urgently.Thanks for the Deligreen team's effort. We receive the balancers on time and no delay for our project. Thank godness

48V Lifepo4 Battery Management System BMS


48V Lifepo4 bms module


Product: Deligreencs Lithium Battery Management 16S40A Lifepo4 BMS 48V Lithium Battery Charge Current 20A With Over Current Protection

(For 3.2V rated LiFePO4 battery pack only)


◆ We can design it for various lithium batteries like LiFepo4, LiMn2O4, and Li-polymer etc.
◆ The main functions are: over charge protection, over discharge protection, over current protection, short-circuit protection, etc.
◆ For Need the temperature protection function , Please contact us to add the temperature sensor.
◆ According to the customer request we can develop PCM in different sizes and structures.
◆ BMS manufactured by high quality Mos and IC imported . Keep your battery long cycle serivce life time.
Our Advantage
◆ 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 100A 120A 200A 250A, , 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.

Different wiring for common port and separate port

BMS wiring directions


First, Preparation before installation.

Make sure the batteries are of good consistency.The volt difference is no more than 0.05V,inner resistance is no more than 5mΩ,capacity difference lower than 30mAh. Connect the batteries in parallel first and then in series.the better performance of batteries consistency is, the higher performance of the BMS.

Second, wiring instructions.

Attention: please use our wires for our BMS.Don’t use other factories’ wires which can’t match with our BMS.

Step 1 B-(blue thick wire): Connect to battery pack total negative pole -

Step 2, Disconnect the wires for batteries from the BMS side.

Step 3,Connect the wires to batteries. Start from the thick black wire to total negative pole(B1-),then connect the 2nd red thin wire to the 1st battery positive pole(B1+)

B2+,B3+B4+......till the last red thick wire.

Step 4,Finishing all the wires to each batteries,don’t plug into the BMS directly. We suggest you use multimeter measure the voltage of two adjacent metal terminals(You can see the white connector with silver metal pins on the BMS).if the voltage is 3.0~4.2V(LiNCM),2.0~3.6V(LiFepo4), 1.5~2.75V(LTO),which means the wiring is correct.

Step 5,Ensure the wires are connected to batteries correctly, all voltage is normal, you can plug the wires into the BMS.


Step 6 P-: Connect P-(black thick wire) to load - and charger -

(if you ordered “common port”)


Charger+ connect to C-(yellow wire) load+ connect to P-(Black thick wire)

(if you ordered “separate port”)


Step 7 charger+ and load+ connect to battery +,please use thick wire


Third, Measure the total volt of the pack, and the output voltage of the BMS.if the voltage is the same,it means the wiring is correct.You can use the BMS now. Otherwise please check the wiring again according to the tips above.





How to test if the bms is good or not?


1. Make sure to use the attached detective wires of our bms.

Ensure volt-detect red wires are connected correctly.


2. Connect the wire to the battery pack,measure the voltage through the wire,it should be equal with the voltage of each cell.

If the votage is different,it means wrong wiring.


3. Make sure the voltage is same,plug the bms in.Make the multimeter point to Ω, measure the resistance between P- and B-. If the resistance is 0, then the BMS is good.
