5. Podešavanje i povezivanje

Before connecting the battery, ensure all devices are turned off and that you are working in a dry, well-ventilated area.

5.1 Početni pregled

Upon receiving your battery, inspect it for any visible damage. If any damage is found, do not attempt to use the battery and contact customer support immediately.

5.2 Povezivanje baterije

The Tewaycell LiFePO4 battery can be used individually or connected in series or parallel for higher voltage or capacity requirements. Always ensure correct polarity when making connections.

  • Priključak za jednu bateriju: Connect the positive (+) terminal of the battery to the positive input of your device and the negative (-) terminal to the negative input.
  • Series Connection (for higher voltage): Za povećanje obimatage, connect the negative terminal of one battery to the positive terminal of the next. The maximum recommended series connection is up to 48V (e.g., four 12.8V batteries for 51.2V nominal). Ensure all batteries in a series string have the same capacity and are fully charged before connecting.
  • Parallel Connection (for higher capacity): To increase capacity, connect positive terminals together and negative terminals together. It is recommended to connect less than 10 batteries in parallel. Ensure all batteries in a parallel bank have the same voltage and are fully charged before connecting.

Use appropriate gauge wiring and connectors for your application to prevent overheating and ensure efficient power transfer. The included screw kit can be used for secure terminal connections.
