This versatile charger is designed to be compatible with most 36V lithium-ion batteries and comes with at least six different plug types. This ensures optimal compatibility regardless of the specific vehicle type. 【Charging Indicator】Features an LED charging indicator light. A red light indicates that charging is in progress, while a green light means the battery is fully charged. Charging automatically stops when the battery reaches full capacity. Larger capacity batteries require longer charging times. The red light indicates active charging; the green light indicates that the battery is fully charged, the device is not connected to a power source, or no charging is currently in progress. 【Multiple Safety Features】Features an aluminum heat sink and a superior heat dissipation system to effectively dissipate heat from the power supply. A built-in intelligent protection module effectively prevents short circuits, overcurrent, and overload, protecting the charger itself. Additional safety features - including overvoltage, overheating, over-discharge, and cycle protection - ensure a safe and worry-free user experience. 【Wide Compatibility】A 36V charger suitable for electric scooters, self-balancing scooters, and Xiaomi scooters. Compatible with Xiaomi M365, Ninebot ES4, ES3, ES2, ES1, two-wheel self-balancing scooters, drift boards, and various other personal mobility aids.
