From the shop's description

Battery Capacity/ Voltage Tester GY-6 The GY-6 LCD Battery Capacity/Voltage Tester is a versatile monitoring module designed to display real-time battery voltage and charge levels. Compatible with various battery chemistries, including lithium-ion, lead-acid, and lithium iron phosphate (LiFePO₄), this device is ideal for applications such as electric bikes, scooters, solar systems, and DIY battery packs. Featuring a clear LCD screen, the tester displays both voltage and remaining battery capacity as a bar graph and percentage. It supports a wide input voltage range and automatically adapts to 12V, 24V, 36V, or 48V systems. Its compact design and easy panel mounting make it a convenient addition to any energy management system or mobile power setup. Features: Clear LCD screen displays voltage and charge percentage. Compatible with multiple battery types (Li-ion, LiFePO₄, lead-acid). Supports common system voltages: 12V, 24V, 36V, 48V. Automatic detection of battery type and voltage range. Visual battery bar and numeric percentage indicator. Simple 2-wire connection for quick integration. Compact and lightweight design for easy installation. Protective screen cover to reduce glare and damage.
