8 Channel 18650 Battery Capacity Tester, Automatic Charge Discharge Module with Internal Resistance Test for Flat Top Batteries, Type-C Powered Lithium Battery Analyzer

Compact & Universal Design: Supports flat-top 18650 batteries ( 2.5V - 3.5V discharge, 4.2V charge) for easy, convenient testing
Working voltage: Powered by DC5V (cable not included) with high-temperature protection and active cooling for reliable operation


8 Independent Test Channels: Perform simultaneous charging, discharging, and capacity tests on up to 8 batteries independently without interference.
Automatic Operation: Supports fully automatic charging and discharging cycles (1-9 cycles adjustable in auto mode). Charging automatically stops when the battery is full.
Internal Resistance Measurement: Utilizes the DC two-wire method to provide reference internal resistance values. For the most accurate reading, measure when the battery is fully charged.
Comprehensive Safety Protections: Features overheating protection and automatic power-off saving for your settings.
Flexible Discharge Voltage: Choose from 11 stop-discharge voltage levels ( 2.5V to 3.5V ).
Ideal for Multiple Applications
Whether you're sorting used 18650 cells for a DIY power bank, testing AA/AAA batteries for household devices, or maintaining your RC car battery collection, this tester provides the critical data you need.
Imagine quickly identifying weak cells in a batch, ensuring only the best performers go into your projects.
Important Usage Notes:
After installing a battery, wait a few seconds for the voltage and internal resistance readings to stabilize.
Discharge current is fixed at a maximum of ~1A (non-adjustable, non-constant current). Charging voltage is fixed at 4.2V.
Not compatible with LiFePO4 batteries.
Internal resistance readings may appear high at low voltages; reinstall the battery for a more accurate measurement.
