Product advantages:

*Advantages: it supports 500A continuous current output, and the peak current can reach 2000a. It is not easy to be heated and damaged. If damaged, the main control will not be affected. You only need to replace the relay to reduce maintenance costs. Current relay power consumption: 250mA.

*The relay is a main circuit switch. You can choose different currents, but the maximum current does not exceed 500A. It is recommended that the working power consumption be less than 500mA. BMS only provides 12V control voltage to control the introduction of relay.

*We recommend that the customer match the relay himself.

1. BMS built-in bluetooth module can be used to view battery parameters on the phone( compatible with Android and IOS).

2. You can develop your own application system according to your own needs. We can provide BMS interface communication protocol.

3. The main protection functions of BMS are: overcharge protection, overdischarge protection, overcurrent protection, balance protection, short circuit protection, BMS low voltage sleep, NTC temperature control protection, etc.

4. The application can adjust hardware and software parameters and support Li ion, LiFePO4, LTO and other batteries.

5. It can be compatible with 3S-32S lithium battery pack. The length of the balanced cable is about 800mm. There are marks on each cable such as B-, B1+, B2+……B16+, B+. This is a very convenient design for welding cables.

6. Static balance: setting the battery voltage difference between 0.02V-0.05V, it will automatically turn on the balance function.

7. Application: large vehicle starting power, solar energy storage, engineering vehicle, low speed four wheeled vehicle, RV or any other device you want to place.

8. The protection parameter settings and modified:

Charge and discharge high temperature and low temperature, battery pack overvoltage and undervoltage, unit cell overvoltage and undervoltage, short circuit and differential pressure value, balance voltage can be modified. It can also reset and restore factory settings.

9. If you choose the BMS + relay + hall sensor + precharge resistance option, we may send it to you by fast shipping method. If the order is suitable for fast shipping(like Fedex), we will contact you before shipment.

10. If you have no experience in BMS, we don't recommend ordering I'm so sorry.

If you have any questions about the options, please feel free to contact us.

Extra RS485 and Diode recommended link

4. Coulometer SOC

Support bidirectional current detection, collect current and voltage with high accuracy, and calculate battery capacity through BMS.

5. BMS manual switch

BMS can be shut down manually through hardware switch.

6. Temperature sensor

Collect the current temperature of the battery environment in real time, and support the adjustment of high and low temperature BMS power-off function.

7. Communication isolation

The CAN, RS485 and UART communication functions of this BMS have isolation and strong anti-interference.

8. Battery balance function

Battery assisted static balance, automatically turns on when there is a voltage difference in the battery, and the balance current is 60mA.

9. New Energy Vehicle Relay

Using 12V-24V weak current control relay to work, can withstand very large current output, and will not heat, even if it is damaged, it is easy to replace.

10. Hall sensor

It is used to detect current input and output information, and send the information to BMS to calculate SOC. Overcurrent protection can be set, error 2%, range 600A.

11. Configure special harness

The functional position of each wiring harness is different, but the function is the same. To ensure safe use, please read our PDF manual before installing it.
