The LED color indicates the battery chemistry: Red for lithium ternary, Green for LiFePO4, and Yellow for lead-acid.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I know how much charge is remaining with this voltage meter module?\u003c\/h4\u003e\n\u003cp\u003eA: The module displays 4 LED segments representing charge level. As the battery discharges, LEDs turn off one by one, giving you a quick visual readout of remaining capacity. The display refreshes every 500ms for near real-time accuracy.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I install this battery indicator module into a custom enclosure or panel?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! At just 46mm × 15mm × 3mm, this slim module is designed for easy integration into battery panels, RC vehicle dashboards, DIY power bank enclosures, and other compact builds. Its low 10mA working current also means minimal impact on your overall battery system.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I set the correct battery string number on the module?\u003c\/h4\u003e\n\u003cp\u003eA: Press and hold the button for 2 seconds to enter setting mode, select your battery type with a brief press, then press and hold again for 2 seconds to enter the string number setting. Briefly press to cycle to the correct string count, then press and hold for 2 seconds to save — or the module saves automatically after 5 seconds of inactivity.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Which battery types does this battery level indicator module support?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This module supports 2S–8S LiPo, Li-ion, 18650 lithium ternary, lithium iron phosphate (LiFePO4), and lead-acid battery packs operating within 5V–30V DC.
