3. Kukhazikitsa ndi Kuyika
Proper installation is crucial for the safe and efficient operation of your DALY Smart BMS. Follow these steps carefully.
3.1 Battery Pack Preparation
Before connecting the BMS, ensure your battery pack is correctly assembled. Identify the total positive and total negative terminals of your battery pack. For an 8-string battery pack, ensure all cells are properly connected in series.

3.2 Kuyika kwa Wiring
The wiring sequence is critical. Always connect the black wire to the total negative terminal first, then proceed with the red wires to the positive terminals of each string in ascending order (B1, B2, B3, etc.).
Video 3.1: Detailed guide on connecting the DALY 100 Balance Smart BMS, including battery pack assembly and wiring sequence for the sampling cables.
- Connect B- Wire: Connect the black wire of the sampling cable to the total negative terminal of the battery pack.
- Connect B+ Wires: Connect the red wires of the sampling cable to the positive terminals of each cell string, starting from B1, B2, and so on, up to the last string.
- Secure Excess Cables: If using fewer strings than the BMS supports (e.g., 8S BMS for an 8S pack, but the cable supports up to 17S), securely seal the remaining unused cables with insulation tape to prevent short circuits.
- NTC Cable: Plug the NTC (temperature sensor) cable into the NTC-A port on the BMS.
- B- to BMS: Connect the main B- wire from the battery pack to the B- terminal on the BMS.
- Sampling Cable to BMS: Ikani sampling cable connector into the designated port on the BMS.
- B+ to BMS: Connect the main B+ wire from the battery pack to the B+ terminal on the BMS.
Zofunika: Miswiring protection is limited to 6 strings. Connecting more than 6 strings incorrectly will damage your BMS. Always follow the wiring sequence strictly. If the wiring sequence is reversed, it will lead to BMS damage.
3.3 Verification with Multimeter
Before plugging the sampling cable into the BMS, use a multimeter to measure the voltage of each wire in the wiring harness to ensure the sequence and voltages are correct. The voltage should increase incrementally from B0 to B1, B2, and so on.

4. Malangizo Ogwiritsira Ntchito
The DALY Smart BMS offers various ways to monitor and manage your battery pack.
4.1 Mobile App and PC Software
The BMS supports multi-channel communication through a mobile app (BalanceBMS on iOS & Android) and PC software. These platforms allow you to monitor cell voltages, temperatures, current, State of Charge (SOC), and other critical parameters in real-time. You can also adjust various parameters and settings.

4.2 Accessories and Their Use
- UART Cable: Supports PC connection for monitoring and parameter adjustment. Does not support other equipment connections.
- LCD Screen: Can be connected to UART and RS485 ports to display real-time battery information and change parameters via a 4.3-inch touch screen.
- Kusintha kwa Kiyi: Used to switch the discharge MOSFET on and off. Other functions can be customized.
- Heating Module: Used in cold environments to start the BMS, ensuring optimal performance.
- Inverter Cable: Allows direct connection of an inverter to the BMS.
- WiFi Module: Supports remote control and monitoring.
5. Parallel Connection Precautions
When connecting multiple battery packs in parallel, observe the following precautions:
- Voltage Kufananiza: Onetsetsani kuti voltage of each battery pack is the same before connecting them in parallel. The voltage difference should be less than 1 volt.
- Discharging MOS Disconnection: When paralleling lithium battery packs, manually disconnect the discharging MOS in the Bluetooth APP or PC software. This prevents the battery packs from triggering short circuit protection due to high current during connection.
- SOC Calibration: For 100% SOC calibration, when single cell overvoltage protection level 2 is triggered, the BMS will be calibrated to 100% SOC.

To ensure optimal performance and longevity of your DALY Smart BMS:
- Yang'anani nthawi zonse mawaya onse olumikizirana kuti awone ngati ali olimba komanso kuti ali ndi dzimbiri.
- Keep the BMS unit clean and free from dust and moisture.
- Monitor battery parameters via the mobile app or PC software to identify any anomalies early.
- Ensure proper ventilation around the battery pack and BMS to prevent overheating.
7. Mavuto
If you encounter issues with your DALY Smart BMS, consider the following:
- No Power/No Indication: Check all main power connections (B-, P-) and ensure the sampling cable is correctly inserted. Verify battery pack voltage.
- App/PC Software Connection Issues: Ensure Bluetooth is enabled on your device, or that the UART/RS485/CAN cables are securely connected and drivers are installed for PC software.
- Zowopsa: Refer to the alarm list in the mobile app or PC software for specific fault codes and recommended actions. Common alarms include overvoltage, kusadziperekatage, overcurrent, and overtemperature.
- Nkhani Zolinganiza: Check the balance current and voltage difference settings in the app/PC software. Ensure all cell voltages are within the expected range.
- Mawaya Olakwika: Re-verify all wiring connections, especially the sampling cables, using a multimeter as described in Section 3.3. Incorrect wiring can lead to severe damage.
