Coulometer 80V 100A True Battery Capacity Indicator Voltage Tester

Stop guessing your battery's true state — the Amicikart Coulometer gives you real-time, precision readings of voltage, current, and actual capacity, so you always know exactly how much power you have left.

The Coulometer 80V 100A True Battery Capacity Indicator is a high-precision current-based battery monitor that goes far beyond simple voltage meters. Unlike basic testers that estimate charge from voltage alone, this coulometer measures actual charge flow (in Ah) to calculate true remaining capacity — giving you accurate, reliable data whether your battery is idle, discharging, or actively charging. With a wide voltage range of 8V–80V and a current range of 0–100A, it is compatible with virtually every battery chemistry you use: Lithium-ion (Li-ion), Lithium Iron Phosphate (LiFePO4), Lead-Acid, and Nickel-Metal Hydride (NiMH).

This coulometer is built for real-world Indian use cases — mount it on your e-bike, electric scooter, solar power bank, golf cart, or DIY EV project and get a clear, always-on display of your battery health. The readings remain accurate even during charging cycles, making it ideal for solar setups and overnight charging scenarios where most cheap testers fail completely. Installation is straightforward with a standard shunt-based connection, and the compact display fits neatly on any panel or dashboard.
