4-Slot Battery Capacity Tester for 18650 Battery Type, Digital Battery Power Detector Module

Stop guessing which 18650 cells are dead, fake, or degraded — the amiciKart 4-Slot Battery Capacity Tester gives you precise mAh readings, internal resistance, and real-time voltage data on a vivid colour display, so you always know exactly what's inside your batteries.

This digital battery analyser is purpose-built for 18650 lithium-ion cells and lets you test up to four batteries simultaneously — cutting your testing time by 75% compared to single-slot testers. The 1.77-inch TFT colour screen shows live readings for capacity (mAh), internal resistance (mΩ), voltage (V), current (A), and power (W) — all at a glance. Three automated modes — Charging, Discharging, and Auto Loop — handle the entire test cycle hands-free, with no manual intervention needed. Built-in safety cut-offs automatically stop charging and discharging at safe thresholds, protecting your cells from overcharge and deep discharge damage.

Whether you're a DIY power bank builder, RC hobbyist, flashlight enthusiast, or electronics tinkerer, this tester helps you sort good cells from bad before they ruin your build. It's powered via two Type-C 5V/1A inputs (adapters not included) and supports loop testing from 1 to 9 cycles for thorough capacity profiling. Note: Not compatible with LiFePO4 batteries.
