4.3 Wiring Connections
- Ensure all power sources are disconnected before making any connections.
- Connect the positive (+) terminal of the battery to the positive (+) terminal of your system/load.
- Connect the negative (-) terminal of the battery to the negative (-) terminal of your system/load.
- Use the provided M8 terminal bolts, washers, and insulating caps to secure connections tightly.
- For parallel connections (to increase capacity), ensure all batteries are of the same voltage and capacity. Connect positive to positive and negative to negative. If more than 4 batteries are connected in parallel, use a bus bar.
- Do not connect batteries in series unless explicitly instructed by ECO-WORTHY for specific models, as this model is designed for 1S4P (1 series, 4 parallel) expansion.
