Follow these steps to set up your UMLIFE charger board:

1. Nustatykite jungties taškus: Locate the IN+, IN-, B+, B-, OUT+, and OUT- pads on the charger board.
   

   Vaizdas: Iš viršaus į apačią 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.
2. Prijunkite akumuliatorių: 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.
3. Connect Load (Optional): 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.
4. Prijunkite maitinimo šaltinį: 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.
5. Activate Protection Board: For the first use, it is necessary to connect the power supply to activate the integrated protection board.

Naudojimo instrukcijos

Once connected, the charger board will begin charging the lithium battery. Observe the LED indicators for charge status:

• Įkrovimo indikatorius: 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).
• Jei akumuliatoriaus ttage 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.

Apsaugos savybės:

The board includes an integrated protection circuit to safeguard the battery and the module:

• Per tomastage Apsauga: Neleidžia akumuliatoriui įkrauti viršyti saugios įtampostage riba.
• Apsauga nuo per didelio iškrovimo: Prevents the battery from discharging below 2.4V, extending battery life.
• Apsauga nuo viršsrovių: Limits the output current to 4A to prevent damage from excessive load.

Priežiūra

To ensure the longevity and proper functioning of your charger board:

• Keep the board clean and free from dust and debris.
• Saugokite plokštę nuo drėgmės ar ekstremalių temperatūrų.
• Įsitikinkite, kad visos jungtys yra tvirtos ir tinkamai izoliuotos, kad išvengtumėte trumpojo jungimo.
• Neviršykite nurodytos įvesties tūriotage range (5V-6V) or output current (1A charging, 4A protection limit).
