Сетуп

Како се повезати

1. Ensure the charger's on/off switch is in the ОФФ положај.
2. Connect the DC output cable (red to positive, black to negative) to your 12V LiFePO4 battery. Then connect the Anderson connector.
3. Connect the AC input cable to a standard 100V-120V AC outlet.
4. Turn the charger's switch to the ON position. The power indicator will turn red, and the charging indicator will turn red, signifying active charging.
5. Turn off the switch after charging is complete.

Battery Activation (for deeply discharged batteries)

If your 12V LiFePO4 battery is deeply discharged (below 9V) and won't charge, follow these steps:

1. Искључите батерију са свих уређаја.
2. Allow the battery to rest for 30 minutes. It may automatically recover to above 10V.
3. Ако је батерија волtage is still below 10V, use the LiTime charger's 0V activation function. Connect the charger as described above. The charger will attempt to activate and restore the battery.
4. Alternatively, on a sunny day, connect a 12V LiFePO4 solar charge controller to the battery and charge for 3-10 seconds to wake it up.
5. For 24V batteries, double all voltage values (e.g., if below 18V, protection mode kicks in).

Упутство за употребу

3-Сtage Charging Mode

The LiTime charger employs an intelligent 3-stage charging algorithm to optimize battery performance and lifespan:

1. Pre-Charge Stagе (Т1): Када је батерија волtage is lower than its normal standard and cannot withstand high-current charging, the charger will initiate a limited current pre-charge. This mode activates and prepares the battery, extending its lifetime. When the output voltage reaches the normal value, the charger automatically switches to the next stage.
2. Пуњење константном струјом Сtagе (Т2): When the battery is in the main charging time, the charger will charge the battery with an 80A current. When the battery voltagе пређе подешену вредност, пуњач ће се аутоматски пребацити на следећи stage.
3. Цонстант Волtagе Пуњење Сtagе (Т3): Пуњач се пребацује на Цонстант Волtagе Пуњење Сtagе и струја пуњења се постепено смањује. Када се пуњење волtagе или струја достигне подешену вредност, пуњач аутоматски искључује излазни напонtagе и пуњење батерије је завршено.

Одржавање

To ensure optimal performance and longevity of your LiTime charger, follow these maintenance guidelines:

• Држите пуњач чистим и без прашине и прљавштине. Користите меку, суву крпу за чишћење.
• Обезбедите одговарајућу вентилацију око пуњача током рада како бисте спречили прегревање.
• Regularly inspect cables and connectors for any signs of wear or damage. Replace if necessary.
• Store the charger in a cool, dry, and well-ventilated area when not in use.
