2. Nastavení a připojení
Before connecting, ensure the battery voltage odpovídá výstupnímu hlasitosti nabíječkytage (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.
Kroky připojení:
- 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.

Stav LED indikátoru:
- LED Always on Red: Baterie se nabíjí.
- LED Always on Green: Baterie je plně nabitá.
- 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 Charging Mode:
Nabíječka využívá 3-stage charging process for optimal battery health and efficiency:
- Pre-Charge Stage (T1 - Activating): Pokud je baterie objtage is low, the charger will apply a limited current to activate it. This stage also supports 0V activation to revive batteries under BMS protection.
- Nabíjení konstantním proudem 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.
- Konstantní svtage Nabíjení Stage (T3 - Current Reducing & Charging Completed): Nabíječka se přepne na konstantní objtage charging. The charging current gradually decreases. When the charging voltagPokud proud dosáhne nastavené hodnoty, nabíječka automaticky vypne výstupní napětí.tage a nabíjení baterie je dokončeno.

4. Bezpečnostní opatření
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.
- Jakmile zjistíte, že nabíječka nebo baterie během nabíjení nefunguje správně nebo je poškozena, ihned odpojte vstupní/výstupní kabel nabíječky.
- Do not use other input cables or extend the output connection cable personally, or please contact LiTime customer service.
- Nabíječku neotevírejte, nedemontujte ani neupravujte.
- Nikdy jej nepoužívejte za bouřky.
- Uchovávejte nabíječku a baterii mimo dosah vody, zdrojů tepla, jisker, ohně, hořlavých plynů a nebezpečných chemikálií.
- 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.
