Uputstva za postavljanje
Follow these steps to set up your UMLIFE charger board:
- Identifikujte tačke povezivanja: Locate the IN+, IN-, B+, B-, OUT+, and OUT- pads on the charger board.
Slika: Od vrha prema dolje view of the charger board. This image clearly shows the input (IN+, IN-), battery (B+, B-), and output (OUT+, OUT-) connection points, which are crucial for proper wiring.
- Priključite bateriju: Connect your 3.7V lithium battery to the B+ and B- pads. Ensure correct polarity: B+ to the positive terminal of the battery, and B- to the negative terminal.
- Povežite opterećenje (opciono): If you intend to power a device directly from the charger board while charging, connect your load to the OUT+ and OUT- pads. Note that the "Battery+" and "Output+" terminals are electrically bonded together. The "Output-" and "Battery-" terminals are electrically isolated.
- Povežite napajanje: Insert a USB Type-C cable into the board's Type-C port. Connect the other end of the cable to a 5V to 6V USB power source, such as a mobile phone charger or a compatible PD fast charging head.
- Activate Protection Board: For the first use, it is necessary to connect the power supply to activate the integrated protection board.
Uputstvo za upotrebu
Once connected, the charger board will begin charging the lithium battery. Observe the LED indicators for charge status:
- Indikator punjenja: A red LED typically indicates that the battery is currently charging.
- Charged Indicator: A green or blue LED typically indicates that the battery is fully charged.
Charging Cycle Behavior:
- The charging cycle automatically terminates when the charging current drops to 100mA after reaching the final float voltage (4.2 V).
- Ako je baterija voltage drops below 4.05V (approximately 80% to 90% of capacity), the charging cycle will automatically restart.
- For batteries with voltage below 2.9V, the board initiates a pre-charge phase with a current of 100mA.
Zaštitne karakteristike:
The board includes an integrated protection circuit to safeguard the battery and the module:
- Over-voltage Zaštita: Prevents the battery from being charged beyond its safe voltage limit.
- Zaštita od prekomjernog pražnjenja: Prevents the battery from discharging below 2.4V, extending battery life.
- Zaštita od prekomjerne struje: Limits the output current to 4A to prevent damage from excessive load.
Održavanje
To ensure the longevity and proper functioning of your charger board:
- Keep the board clean and free from dust and debris.
- Avoid exposing the board to moisture or extreme temperatures.
- Osigurajte da su svi priključci sigurni i pravilno izolirani kako biste spriječili kratki spoj.
- Nemojte prekoračiti navedeni ulazni volumentage range (5V-6V) or output current (1A charging, 4A protection limit).
