Flex Adventures Battery Monitor | High-Precision 12V/24V Digital Coulomb Meter

Know Exactly What Your Battery Has Left.

The Flex Adventures Battery Monitor is a high-precision digital Coulomb meter that gives you complete, real-time visibility into your 12V or 24V battery system — voltage, charge/discharge current, remaining capacity (Ah), and critically, the exact time remaining before your battery is empty or fully charged based on your current load.

Unlike simple voltage-based testers that only give you a rough estimate, the Flex Battery Monitor uses a shunt-based measurement system to track actual energy flow in and out of your battery — delivering far greater accuracy for lithium, AGM, gel, and lead-acid systems. The intuitive touch control display with battery symbol and digital readouts makes it easy to assess your power status at a glance, day or night.

🔑 Key Features

• Real-Time Time Remaining — Displays exact time to empty or full based on current load or charge rate
• Shunt-Based Precision — Tracks actual energy flow for far greater accuracy than voltage-only monitors
• Measures Voltage, Current & Capacity — Full visibility into your battery’s health and status
• Touch Control Interface — Intuitive navigation through data and settings
• High-Resolution Display — Battery symbol + digital readouts for quick at-a-glance assessment
• Programmable Alarms — Visual and auditory alerts for low voltage or low capacity states
• Data Memory — Automatically stores latest data during power shutdowns to prevent information loss
• Wide Voltage Range — Compatible with 8V to 120V systems (12V & 24V)
• High Current Measurement — Up to 100A or 500A depending on shunt supplied
• Universal Battery Compatibility — LiFePO4, AGM, Gel, Lead-Acid, and Nickel-metal hybrid
• Flush-Mount Design — Clean, professional installation in any panel or enclosure
