1. Introduzione e oltreview
The LiTime 10 Amp Lithium Battery Charger is designed for 12V (12.8V) LiFePO4 batteries, delivering stable charging through CC/CV modes. It supports 0V activation to revive batteries under BMS protection. This charger is equipped with a built-in cooling fan for efficient operation in various temperature conditions (-4°F to 104°F) and features multiple safety protections. It is suitable for RVs, trucks, cars, and solar systems.

2. Configurazione e connessione
Before connecting, ensure the battery voltage corrisponde alla tensione di uscita del caricabatterietage (14.6V for 12V LiFePO4 batteries). The charger comes with an AC input cable and a DC output cable with an Anderson connector. An M8 terminal adapter is also included for direct battery post connection.
Passaggi di connessione:
- Ensure the charger's power switch is in the OFF position.
- Connect the DC output cable (with Anderson connector or M8 terminals) to your LiFePO4 battery. Ensure connections are firm to prevent overheating.
- Connect the AC input cable to a standard 100V-240V AC power outlet.
- Turn the charger's power switch to the ON position. The charger will begin charging, indicated by the LED status.

3. Istruzioni per l'uso
Stato dell'indicatore LED:
- LED Always on Red: La batteria è in carica.
- LED Always on Green: La batteria è completamente carica.
- LED Flashes Green: Charger is on standby.
- LED Flashes Red: Charger fault or under protection (e.g., over-temperature, reverse polarity, output short-circuit, output over-voltagE).

3-Stage Modalità di ricarica:
Il caricabatterie utilizza un 3-stage processo di ricarica per una salute e un'efficienza ottimali della batteria:
- Pre-Charge Stage (T1 - Activating): Se il volume della batteriatage is low, the charger will apply a limited current to activate it. This stage also supports 0V activation to revive batteries under BMS protection.
- Carica a corrente costante Stage (T2 - 10A Current Charging): When the battery is in the main charging time, the charger will charge the battery with a 10A current. The battery voltage rises above the set value, and the charger automatically switches to the next stage.
- Volume costantetage Ricarica Stage (T3 - Current Reducing & Charging Completed): Il caricatore passa al volume costantetage charging. The charging current gradually decreases. When the charging voltage o la corrente raggiunge il valore impostato, il caricabatterie spegne automaticamente la tensione di uscitatagee la ricarica della batteria è completata.

4. Precauzioni di sicurezza
Always prioritize safety when operating the charger. This charger is designed with multilevel protections to prevent over-temperature, reverse polarity connection, output short-circuit, and output over-voltage.
- Check the battery specifications carefully before charging to ensure that the LiFePO4 battery matches the charger's technical data.
- Make sure the charger is properly connected to the battery. Avoid a short circuit.
- Scollegare immediatamente il cavo di ingresso/uscita del caricabatterie non appena si riscontra che il caricabatterie o la batteria presentano anomalie o sono danneggiati durante la ricarica.
- Do not use other input cables or extend the output connection cable personally, or please contact LiTime customer service.
- Non aprire, smontare o modificare il caricabatterie.
- Non utilizzarlo mai durante un temporale.
- Tenere il caricabatterie e la batteria lontano da acqua, fonti di calore, scintille, fiamme, gas infiammabili e sostanze chimiche pericolose.
- Do not place rods or other metal objects in vents or other openings.
- Place the charger in a well-ventilated area with sufficient heat dissipation to prevent overheating and damage.
- Do not puncture, drop, crush, burn, penetrate, shake, strike, or throw it with force.
- This 12 volt 10 amp lithium battery charger is not waterproof - not suitable for Marine environments such as boats, ships, yachts, trolling motors, etc.

Charger Won't Start?
If your inverter is plugged in, it may be blocking the charger's initial "wake-up" pulse. Follow these steps:
- Unplug the inverter from the battery.
- Let the charger activate the battery.
- Reconnect the inverter after charging is complete.
