    FAQ's

    How do I connect a battery charger?

    Through simple plug-and-play, the connection between the lithium battery and the WattCycle 12V 20A battery charger with the Anderson terminal is quickly established. The red Anderson connection cable of the charger is connected to the positive terminal of the battery (the red terminal of the WattCycle LiFePO4 battery), and the black Anderson connection cable is connected to the negative terminal of the battery (the black terminal of the WattCycle battery).

    What does the battery charger indicate?

    The WattCycle 12V 20A battery charger has an LED display that informs you about the charging status through the color and status of the indicator. If the display stays green, it means that the charging process is complete or no lithium battery is connected. If the display stays red, the battery is being charged. If the red light on the display blinks, there is an issue with the charging process.

    How does a lithium battery charger work?

    The WattCycle 12V 20A battery charger is designed for 12V lithium batteries, assuming a 3-stage charging mode (pre-charge phase, constant current phase, and constant voltage phase).

    Can this charger reactivate a lithium battery that has triggered the BMS protection?

    Yes, the WattCycle 12V 20A battery charger has an activation function for lithium batteries. In the case of BMS protection, the LiFePO4 charger can reactivate the LiFePO4 battery and restore the normal voltage.

    How long does it take to charge a 100Ah lithium battery with 20 amperes?

    When charging a 100Ah lithium battery with a WattCycle 12V 20A charger, the charging time is 100Ah / 20A = 5 hours.

    How long does a 20A charger take to charge a 200Ah battery?

    When charging a 200Ah lithium battery with a WattCycle 12V 20A charger, the charging time is 200Ah / 20A = 10 hours.
