No.	Function	Description
1	Dial switch	When PACK is used in parallel, different PACKs can be distinguished by setting the address through the 4-bit dial switch on BMS. The address should not be set to the same.
2	Key function	1. When the BMS is in sleep state, press the button (3-6S) and release it. The protection board is activated, and the LED indicator lights up from "RUN" one by one for 0.5 seconds. 2. When the BMS is in active state, press the button (3-6S) and release it. The protection board will be put to sleep, and the LED indicator light will be lit sequentially from the lowest power light for 0.5 seconds. 3. When the BMS is in active state, press the button (6-10S) and release it. The protection board will be reset and all LED lights will light up simultaneously for 1.5 seconds.
3	communication interface	The 1RS485A/B connector allows multiple devices to be connected in parallel to increase the battery capacity. 2. The RS232 interface communicates with the upper computer, so that the battery information can be monitored through the upper computer. 3. RS485/CAN communication and inverter communication.
4	SOC estimation and display	It has SOC estimation function and displays the remaining power through 6 green LEDs.
5	status display	The operating status is displayed through a green LED display system.
6	A fault warning is displayed	A red LED display system shows a fault
7	SOH estimate	There is an SOH estimation function
8	Beep function	In case of fault, it will ring for 0.25S every 1S; When protection is in place, it will beep for 0.25S every 2s (except overvoltage protection); When an alarm is issued, it will sound for 0.25S every 3s (except for overpressure alarm);

FAQ

Q1.How to strictly control battery safety and quality?
Safety testing is the most important part of our batteries quality test,extreme condition testing such as overcharging, overdischarging, short circuit, needle puncture, and high temperature (such as 85ºC storage).
Capacity Test: Verify whether the actual capacity meets the nominal value through charge and discharge cycles.   
Cycle life test : ≥ 80% after 2000 cycles. 
Pass CE,UL,Rohs,TUV,MSDS,UN38.3 on the basis of ISO9001 management system.  
 
Q2.What's the good way to make batteries in group keep best performance?
Consistency screening is firstly done before batteries are divided into group.
-Eliminate cells with significant differences in voltage, internal resistance, and capacity (such as pairing within ± 1%) through capacitive devices.   
-Using Dynamic Parameter Grouping (DVA) to match individual cells within the battery pack.
s of batteries to more than 90 countries etc.

Q3:How to get long the usage life through measures and maintenance?
1.Optimize charge and discharge management
-Avoid deep discharge (for example, lithium-ion batteries are recommended to maintain a range of 20% to 80% power).
-Use intelligent BMS (battery management system) to control the charging cutoff voltage (such as ternary lithium battery ≤ 4.2V/single cell).
-Do not charge at high temperature (>45ºC) or low temperature (<0ºC).
2. Temperature control
-Install a heat dissipation system (air cooling/liquid cooling) to maintain the operating temperature between 15 and 35ºC.
-Avoid heating caused by long-term high rate discharge (e.g.>1C).
3. Regular maintenance and monitoring
-Balanced charging: BMS regularly calibrates the difference in individual voltages (e.g., passive/active balancing).
-Storage advice: Keep 50% power when not in use for a long time, and recharge every 3 months.

 Q4:What are your strengths, export experience and domestic and foreign use cases?
Our company has obtained the high-tech enterprise certificate issued by the government, received special support from the government, and won the invitation and bid for the solar energy storage project of the bus station. 
Our technology department had designed and manufactured batteries for products of the world's top 500 enterprises, which have been used for more than 10 years without fire or explosion accidents.
