135 -
136 -1. Connect the BMS Main to the first BMS Logic 12 (P15 -> X3).
137 -1. Connect the BMS Logic 12 to each other (X4 -> X3).

141 -(((
142 -**Recommendations:**
143 -~1. The total cable length (the sum of the lengths of all cables) between the BMS Main and the last BMS Logic 12 should not exceed 500 meters.
144 -2. Make all connections with the same cable.
145 -3. For a total cable length of more than 10 meters use twisted pair with the 120 Ohm wave impedance.

148 -=== Connecting battery cells ===
149 -
150 -To connect the battery cells, follow Figure 16. Incorrect connection of the cells can damage the BMS Logic 12.
151 -
152 -Begin the connection with the negative of the battery: the "V-" of the first BMS Logic 12 is connected to "B-", then the first cell (C1) of the battery is connected, then the second (C2), etc. The “V-“ of the next BMS Logic 12 is connected to the C12 of the previous BMS Logic 12. If not all inputs of the cells are used, then the remaining inputs are connected to the cell with the highest potential.

163 -=== Connecting thermistors ===
164 -
165 -Thermistors should be fastened to the cells, excluding short circuits to the cell terminals (for example, isolate thermistors with heat shrink). For reliable operation, it is recommended to use all thermistors (a temperature sensor per cell).
