3-color Battery Capacity Indicator For Lithium and Lead Acid
The 3-Color Battery Capacity Indicator is a compact monitoring module designed for both lithium and lead-acid batteries. It operates within a wide voltage range of 2.5V to 24V and can measure up to 300V using an external resistor setup. The indicator displays battery status using a 3-color LED system (red, orange, green) for clear visual feedback. It supports two display modes, linear (A) and dot matrix (P), and offers fast response time under 1ms. With low power consumption and simple 2-wire connection, it is ideal for battery monitoring in energy systems, electric vehicles, and DIY electronics projects.
وحدة مؤشر سعة البطارية ثلاثي الألوان هي جهاز صغير لمراقبة حالة البطاريات من نوع ليثيوم أو رصاص حمضي. تعمل ضمن نطاق جهد من 2.5 فولت إلى 24 فولت ويمكنها قياس حتى 300 فولت باستخدام مقاومة خارجية مناسبة. تعرض حالة البطارية باستخدام ثلاثة ألوان (أحمر، برتقالي، أخضر) لتوضيح مستوى الشحن بشكل بصري واضح. تدعم وضعين للعرض الخطي (A) ونمط النقاط (P)، مع سرعة استجابة أقل من 1 مللي ثانية. تتميز بسهولة التوصيل واستهلاك منخفض للطاقة، وتستخدم في أنظمة الطاقة، والمركبات الكهربائية، والمشاريع الإلكترونية.
The 3-Color Battery Capacity Indicator is a versatile voltage monitoring module designed to display the real-time charge level of both lithium and lead-acid batteries. It provides a simple and effective visual representation of battery status using a multi-color LED bar system consisting of red, orange, and green indicators.
The module operates over a wide input voltage range and can also be adapted for high-voltage measurement applications up to 300V using an external resistor-based sampling method. This makes it suitable for a broad range of power systems.
With selectable display modes, including linear (A mode) and dot matrix (P mode), users can customize how battery levels are shown. Its fast response time ensures near-instant updates of battery status, making it highly reliable for real-time monitoring.
Designed with low power consumption and simple 2-wire connection, the module is easy to integrate into existing systems without complex wiring.
