42V 2A Charger for 36V Electric Scooter Ebike Lithium Batteries

42V 2A Lithium Battery Charger with Multiple Protections and Fast Charging Capabilities

The 42V 2A lithium battery charger is designed with a three-stage charging mode to ensure efficient and safe charging. The charging process consists of the following stages:

Stage 1: Constant Current Charge (2A) Stage 2: Constant Voltage Charging (42V) Stage 3: Trickle Charge

The charger's intelligent control system helps to improve the overall charging efficiency, while the three-level charging mode helps prevent overcharging, overheating, and excessive current, ensuring the safety and longevity of the battery.

This high-current fast charger is specifically tailored for 36V lithium-ion battery packs, making it an ideal choice for electric scooters, bikes, and other similar devices. It is not recommended for use with lead-acid battery packs.

The charger is equipped with multiple protection functions to ensure the safety of the charging process:

1. Over-Current Protection
2. Over-Charge Protection
3. Over-Voltage Protection
4. Short Circuit Protection
5. High Temperature Protection

These safeguards give users peace of mind, as the charger will automatically maintain the battery's health as long as it is plugged in.

The 42V charger is designed with multiple adapter ports, allowing it to accommodate a variety of battery connector types. It comes with the following adapters:

1. Adapter to convert a 5.5 single-prong DC plug to an 8mm three-prong connector
2. Adapter to convert a 5.5 single-fork DC plug to an 8mm RCA connector
3. Adapter to convert a 5.5 single-prong DC plug to a DC5.5 * 2.5mm 1-pin DC plug

This versatility ensures the charger can be used with a wide range of 36V lithium-ion battery packs, making it a universal solution for electric scooters, bikes, and other compatible devices.

In the event that the charger does not appear to be functioning, the user can follow a few simple steps for inspection:

1. Test the battery's health, especially if the battery has been used for more than 12 months or not used for 2-3 months.
2. Check if the positive and negative (+/-) connectors of the charger match the size of the battery connector. If not, try changing the connector to connect with the battery.
3. If the green light turns off when the battery is connected, it may indicate an internal short circuit in the battery, causing the charger's self-protection function to activate. In this case, the battery should be checked.
4. If the green light is on when plugged into the power supply and the LED shows a red light when connected to the device, it means the charger is working properly. The LED will turn green once the battery is fully charged.

The 42V 2A smart charger is compatible with a wide range of electric scooters, including models from Gotrax, Swagtron, Brid, Segway, Ninebot, Razor, and more. It is a versatile and reliable solution for fast, safe, and efficient charging of 36V lithium-ion battery packs.
