• Ħajja taċ-Ċiklu Estiża: Offers a significantly longer lifespan with at least 2000 cycles at 100% Depth of Discharge (DOD), and retains 80% capacity even after 3000 cycles. This is up to 10 times longer than typical lead-acid batteries.
• Sistema ta' Ġestjoni tal-Batterija Inkorporata (BMS): The integrated BMS actively monitors and manages the battery's real-time status. It provides essential protections including:
  • Vol baxx u GħolitagProtezzjoni ta' Qtugħ elettroniku
  • Protezzjoni ta 'ħlas żejjed
  • Protezzjoni ta 'skarika żejda
  • Protezzjoni ta 'kurrent żejjed
  • Protezzjoni Short Circuit
  • Cell Balancing for optimal performance and longevity
• Rata Baxxa ta' Awto-Kwittanza: Maintains charge for longer periods when not in use.
• 10-Year Lifetime: Engineered for long-term durability and performance.

5. Setup u Konnessjoni

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

5.1 Spezzjoni Inizjali

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 Konnessjoni tal-batterija

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.

• Konnessjoni ta' Batterija Unika: 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): Biex jiżdied il-voltage, 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.
