The 42V 2A 3-in-1 intelligent universal charger is suitable for charging 36V lithium batteries. This charger offers a convenient and efficient charging solution for multiple devices.

Before attempting to charge, it is important to first check the battery's health status. If the battery has been in use for more than 12 months or has not been used for 2-3 months, this may affect the charger's performance.

If the green light is illuminated when the power is plugged in, but the charger does not work after the battery is connected, and the green light remains on, this could be due to a mismatch between the positive and negative (+/-) connectors of the charger and the battery. In such cases, you can try changing the connector to better fit your battery.

Alternatively, if there is a green light when plugging in the power, but the green light goes out when the battery is connected, this could indicate an internal short circuit in the battery. This causes the charger's self-protection function to activate, and you should check the condition of the battery.

It is important to note that this 42V 2A 3-in-1 charger is only suitable for 36V lithium-ion batteries and should not be used with lead-acid batteries or other voltage versions such as 24V, 25.2V, or 29.4V.

The LED light indicators on the charger provide quick and clear feedback on the charging status. The red light indicates that the battery is currently charging, while the green light signifies that the battery is fully charged.

This 42V 2A charger (with 3 plugs) is designed for efficient and intelligent charging of 36V lithium batteries. It features a CC-CV (constant current-constant voltage) working mode, which allows the charger to automatically adjust the charging process to ensure optimal performance.

The charger is equipped with several safety features, including overvoltage protection, overcurrent protection, short-circuit protection, and overtemperature protection, ensuring a safe and reliable charging experience.

One of the key advantages of this 42V 2A charger is its versatility. It comes with three different output ports (DC5.5 * 2.1mm 1-pin, 8mm 3-pin, and RCA 8mm DC plug), making it compatible with a wide range of products, such as Gotrax, Jetson, Hiboy, Voyager, Xiaomi chargers, Lime, Lime-S, and Segway Ninebot ES1, ES2, ES4, E22, ES1L.

With a powerful 84W output and intelligent charging capabilities, this 42V 2A charger can efficiently and conveniently charge multiple devices simultaneously, without the need for constant monitoring. Its compact and lightweight design makes it easy to transport and use, providing a hassle-free charging experience for users.
