1. Sarrera eta Overview
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. Konfigurazioa eta konexioa
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.
Konexioaren urratsak:
- 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.

LED adierazlearen egoera:
- LED Always on Red: Bateria kargatzen ari da.
- LED Always on Green: Bateria guztiz kargatuta dago.
- 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-voltageta).

3-Stage Charging Mode:
Kargagailuak 3 segundoko bateria erabiltzen du.tage charging process for optimal battery health and efficiency:
- Pre-Charge Stage (T1 - Activating): Bateria boltage is low, the charger will apply a limited current to activate it. This stage also supports 0V activation to revive batteries under BMS protection.
- Korronte konstanteko karga 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.
- Konstante Voltage S kargatzentage (T3 - Current Reducing & Charging Completed): Kargagailua bolumen konstantera aldatzen datage charging. The charging current gradually decreases. When the charging voltage edo korrontea ezarritako baliora iristen denean, kargagailuak automatikoki itzaltzen du irteerako bolumenatage eta bateria kargatzen amaitu da.

4. Segurtasun-neurriak
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.
- Kargagailua edo bateria kargatzen ari den bitartean anormal edo kaltetuta dagoela ikusi ondoren, deskonektatu kargagailuaren sarrera/irteerako kablea berehala.
- Do not use other input cables or extend the output connection cable personally, or please contact LiTime customer service.
- Ez ireki, desmuntatu edo aldatu kargagailua.
- Ez erabili inoiz ekaitz batean.
- Kargagailua eta bateria uretatik, bero-iturrietatik, txinpartetatik, sugarretatik, gas sukoietatik eta produktu kimiko arriskutsuetatik urrun eduki.
- 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.
