Follow these steps carefully to install your DALY Smart BMS. For visual guidance, refer to the installation video below.

4.1. Батареяны даярдоо

1. Identify the total positive terminal (B+) and total negative terminal (B-) of your battery pack.
2. Ensure all individual cells are properly connected in series.

4.2. Сampling Cable Connection

The metal ring terminals for the sampling cables are user-supplied.

1. Connect the first black cable (B-) and the blue B- wire from the sampling cable to the total negative terminal of the battery pack.
2. Connect the remaining sampling cables in order, from B1 to B+ (or B8 for an 8S pack), to the positive terminals of each cell.
3. Абайлаңыз: If using fewer series than the maximum supported by the BMS, do not short-circuit the excess wires. Instead, securely tape them up with insulation tape to prevent accidental contact.
4. Connect the B+ wire (red) from the sampling cable to the total positive terminal of the battery pack.

4.3. Wiring Verification

Before connecting the sampling cable to the BMS, verify the wiring using a multimeter:

1. Place the black probe of the multimeter on B0 (the first pin of the sampling cable, connected to the total negative terminal).
2. Place the red probe on B1, then B2, B3, and so on, sequentially.
3. Observe the multimeter readings. If the multimeter displays positive voltage readings that increase step by step (approximately 3-4V per step for typical lithium cells), the wiring is correct.
4. Маанилүү: During this testing, do not let the two multimeter probes touch each other, as this may cause a short circuit in the cable.

4.4. BMS Connection

1. Connect the main B- wire from the battery pack to the B- terminal on the BMS.
2. Insert the temperature sensor (NTC) into the designated NTC port on the BMS.
3. Carefully plug the sampling cable connector into the corresponding port on the BMS.
4. Connect the main B+ wire from the battery pack to the B+ terminal on the BMS.
5. Once all connections are secure, check the BMS. If the green light on the BMS is illuminated, the BMS is working properly.
