4. Podešavanje i povezivanje
Follow these steps to connect your OptiMATE TM-497 charger to a 12.8V LiFePO4 battery:

- Kabel s krokodil štipaljkom: For temporary charging, attach the red alligator clip to the positive (+) battery terminal and the black alligator clip to the negative (-) battery terminal. Ensure clips are firmly attached and do not touch each other or other metal parts.
- Connect Charger to Battery Cable: Plug the chosen battery connection cable (vehicle side or alligator clip) into the output port of the OptiMATE TM-497 charger.
- Priključite na naizmjeničnu struju: Plug the AC power cord into a standard 100-240V AC wall outlet. The charger will automatically begin its charging program.
