1. Увод и крајview
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. Подешавање и повезивање
Before connecting, ensure the battery voltage matches the charger's output voltage (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.
Кораци повезивања:
- 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.

Статус ЛЕД индикатора:
- LED Always on Red: Батерија се пуни.
- LED Always on Green: Батерија је потпуно напуњена.
- 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-voltagи).

3-Сtage Charging Mode:
Пуњач користи 3-сtage charging process for optimal battery health and efficiency:
- Pre-Charge Stage (T1 - Activating): Ако је батерија волtage is low, the charger will apply a limited current to activate it. This stage also supports 0V activation to revive batteries under BMS protection.
- Пуњење константном струјом Сtage (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.
- Цонстант Волtagе Пуњење Сtage (T3 - Current Reducing & Charging Completed): Пуњач прелази на константну запреминуtage charging. The charging current gradually decreases. When the charging voltagе или струја достигне подешену вредност, пуњач аутоматски искључује излазни напонtagе и пуњење батерије је завршено.

4. Мере предострожности
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.
- Одмах искључите улазно/излазни кабл пуњача чим се утврди да пуњач или батерија не раде исправно или су оштећени током пуњења.
- Do not use other input cables or extend the output connection cable personally, or please contact LiTime customer service.
- Не отварајте, не растављајте и не модификујте пуњач.
- Никада га не користите током грмљавине.
- Држите пуњач и батерију даље од воде, извора топлоте, варница, пламена, запаљивог гаса и опасних хемикалија.
- 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.
