12V 24V 36V 48V Battery Indicator, Waterproof Universal LED Display Ba-ttery Meter Gauge for Lithium, LiFePO4, Lead-Acid (24V Pb-Acid Battery Indicator)

This battery indicator works with general 12V, 24V, 36V, and 48V lead-acid, Lithium, and LiFePO4 storage batteries. It employs a 10-bit ADC MCU to gauge battery voltage and power level, featuring a robust battery level testing system and a distinctive design. It automatically enters sleep mode after 30 seconds of inactivity, aiding in energy conservation. Charger indicator: Fitted with a five-segment LED display, it shows battery power levels from 10% to 100%. It signals when to recharge the battery: when capacity is 10%, only 1 LED bar remains lit; when capacity is 20%, 1 LED bar flashes as a reminder; when capacity is 30%, 1 LED bar stays lit while another flashes. Operational mistakes are no longer a worry! Understanding the concerns during installation, this battery monitor includes advanced built-in reverse polarity protection. It effectively guards the core components against damage from incorrect wiring, offering comprehensive safety protection. Used for: This product is appropriate for use in a wide range of fields, including various lead-acid batteries (such as AGM, Calcium, GEL, MF, EFB, SLA, VRLA, WET, etc.), automobiles, trucks, RVs, motorcycles, electric bicycles, tricycles, boats and yachts, golf carts, sightseeing vehicles, electric forklifts, solar photovoltaic systems, wind power generation systems, UPS uninterruptible power supplies, home energy storage battery cabinets, communication base stations, security monitoring systems, medical and emergency equipment, children's toy vehicles, and models. The battery capacity indicator is not merely for "checking how much power is left." Its core value lies in: 1) Over-discharge Protection: It issues a warning when voltage or capacity drops to a set threshold, prompting users to recharge promptly to avoid permanent damage caused by deep discharge. 2) Usage Optimization: It helps users reasonably arrange electrical appliance usage based on battery status. 3) Safety Enhancement: It prevents equipment shutdowns or accidents (such as failure of vehicle lighting during nighttime driving) due to sudden battery depletion
