Which battery voltages and chemistries is this coulometer compatible with?

The meter supports any DC system in the 0–120V range, making it compatible with 12V, 24V, 36V, 48V, 72V, and 96V batteries regardless of chemistry — lead-acid, lithium-ion (LiFePO4, NMC), gel, AGM, or nickel-based. You simply configure the nominal voltage and capacity in the settings menu.

How does the wireless connection work, and what is the maximum reliable range?

The display module and measuring module communicate over a short-range wireless protocol (similar to 2.4 GHz RF). The manufacturer specifies a reliable operating range of up to 10 metres, which covers most vehicles, solar sheds, and small battery rooms. For longer cable runs, the included USB cable can be used as an alternative wired connection.

Does the 100A shunt need to be installed on the positive or negative cable, and what wire gauge is recommended?

The 100A shunt is typically installed on the negative (ground) side of the battery in series with the load circuit — this is the standard and safer practice for most DC systems. For continuous 100A loads, use a minimum 35 mm² (AWG 2) copper cable to the shunt terminals to prevent voltage drop and heat build-up.

How do I set the over-voltage and under-voltage protection thresholds?

Protection thresholds are configured directly on the display module using the onboard buttons — hold the SET button to enter the protection menu, then use the UP/DOWN keys to adjust over-voltage, under-voltage, and over-current limits to your desired values. The meter will trigger an alert (and can cut output via a relay if wired) when any threshold is breached.

What is the accuracy of the voltage and current measurements?

The coulometer measures DC voltage across the 0–120V range and current across 0–100A using the precision shunt resistor. Typical accuracy for this class of coulometer is ±1% for voltage and ±1% for current readings, which is sufficient for battery state-of-charge monitoring, solar charge tracking, and load management in most DIY and semi-professional applications.

Stop guessing your battery's health — the amiciKart DC 100A 120V Wireless Coulometer gives you real-time voltage, current, power, capacity, runtime, and temperature on a single LCD, so you always know exactly what your battery is doing.

This dual-module coulometer separates the display unit from the measuring/shunt unit, letting you mount the shunt right at the battery bank while placing the bright LCD screen wherever it's most convenient — up to 10 metres away via wireless connection or USB cable. Whether you're managing a 12V car battery, a 24V solar storage bank, a 48V e-rickshaw pack, or a 96V industrial system, the wide 0–120V / 0–100A measuring range has you covered. The large LCD simultaneously shows DC voltage, current, power (up to 200 kW), charge capacity (1–99%), elapsed time (up to 99 days), and ambient temperature (−20°C to 120°C) — no switching between screens, no guesswork.

Built-in adjustable protection lets you set custom over-voltage, under-voltage, and over-current thresholds to safeguard your batteries and connected equipment. Setup is straightforward: connect the shunt in series with your battery, pair the display wirelessly, and you're live in minutes — no electrician required for most DIY installations.

Ideal for solar home systems, EV conversions, inverter battery banks, marine setups, and off-grid power stations. Backed by a 1-year warranty and dedicated post-sale support via WhatsApp, call, or email — reach the amiciKart team at 📞 980-970-9898 or ✉️ care@amicikart.com. Ships free across India with same-day dispatch on orders placed before 2 PM.

Monitor from anywhere — wireless dual-module design lets you mount the display up to 10 metres away from the shunt, so readings are always in sight without messy long cable runs
Six parameters on one screen — simultaneously tracks DC voltage, current, power, charge capacity (Ah), runtime and temperature on a clear LCD, eliminating the need for multiple instruments
Wide compatibility — measures DC 0–120V / 0–100A / 0–200KW, making it suitable for 12V, 24V, 48V and 96V battery banks in solar, EV, inverter and marine applications
Customisable protection alerts — set your own over-voltage, under-voltage, over-current and limit thresholds to safeguard your battery system automatically
