Precision Battery Monitoring with the Votronic 200A Smart Shunt and Remote LCD Display

Accurate, Real-Time Insight for 12V and 24V Battery Systems

The Votronic 200A Battery Monitor (Model 200S) provides a clear, real-time view of your battery's state of charge, current flow, and voltage. Unlike basic voltage-based indicators, this unit uses a 200A precision smart shunt to measure actual energy entering and leaving the battery, delivering a true 'fuel gauge' for lead-acid, gel, AGM, and LiFePO4 banks. The bright, white-illuminated LCD display presents remaining capacity in both ampere-hours (Ah) and percentage (%), so you always know exactly how much usable energy remains.

Designed for 12V and 24V systems, the monitor also tracks the voltage of a secondary battery, such as a vehicle's starter battery, giving you complete oversight of your dual-battery setup. A programmable switching output can automatically disconnect loads when the battery reaches a user-defined low state of charge, preventing harmful deep discharge and extending battery service life.

Why a Shunt-Based Monitor Outperforms Voltage-Only Gauges

Voltage-based battery indicators can be misleading, especially under load or during charging. The Votronic 200S employs a microprocessor-controlled, shunt-based measurement system that counts every amp-hour in and out. This eliminates guesswork and provides a reliable state-of-charge reading regardless of surface charge or voltage sag. The included 35mm² braided copper ground strap ensures a low-resistance connection, maintaining accuracy even at high currents up to 200A continuous (300A for 15 minutes, 400A for 7 minutes).

For installers and system integrators, the smart shunt features M8 bolt terminals (approx. 5/16"-18) for secure high-current connections and an RJ12 socket for the plug-and-play communication cable to the remote display. The compact shunt (135x32x44mm) and shallow display mounting depth allow flexible installation in tight spaces, such as behind panels or in vehicle cabins.

Key Features

• 200A smart shunt with microprocessor-controlled coulomb counting for precise state-of-charge tracking
• Bright LCD remote display shows remaining capacity (Ah and %), real-time current (A), voltage (V), and secondary battery voltage
• Programmable low-voltage disconnect protects batteries from harmful deep discharge; includes an emergency override button
• Compatible with 12V and 24V systems and multiple battery chemistries: lead-acid, gel, AGM, LiFePO4
• Plug-and-play installation with included communication cable, 35mm² braided ground strap, and compact shunt design
• Ultra-low power consumption (~5mA) minimises drain on the monitored battery

Built for Demanding Mobile and Off-Grid Applications

Whether you're managing a caravan solar system, a 4WD dual-battery setup, or a marine electrical system, the Votronic 200S reduces the risk of unexpected battery failure. By providing accurate, real-time data, it helps you make informed decisions about energy usage and charging. The automatic load disconnect function safeguards your battery investment, while the secondary battery voltage display keeps you aware of your vehicle's starting battery health.

Unlike generic battery monitors that rely on voltage alone, the Votronic 200S accounts for charging and discharging currents, giving you a true picture of battery state. This is particularly valuable for LiFePO4 batteries, where voltage remains flat for most of the discharge curve. The monitor's ability to handle up to 400A for short durations makes it suitable for high-surge loads like inverters or winches.
