- High precision remaining battery life reading using the LM3914 analog voltage sensing technology, enabling accurate monitoring of how much capacity is left. - LED operating indicators provide a clear, at-a-glance view of the current battery level. - Adjustable display range allows the indicator to be tailored to different battery capacities and usage patterns. - Compatible with Lithium batteries, lead-acid batteries, and other common battery chemistries, making it suitable for a wide range of applications. - Reliable, easy-to-integrate solution for battery monitoring in various projects and systems. Use scenarios - Solar or off-grid systems: monitor a battery bank (Li-ion or lead-acid) to prevent deep discharge and optimize charging cycles. - Portable power, UPS, or emergency backup devices: quickly assess remaining runtime and plan recharging or replacement before power runs out. - Hobby or DIY projects: integrate with RC vehicles, drones, or electronics projects using Li-ion/LiPo or other common chemistries to know when to recharge or replace batteries.
