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

Technical Specifications

Product Name: 2.4-inch Color Screen 8-Channel 18650 Battery Capacity Tester with Curve Display

Operating Voltage: DC 5V 10A (unit only, power supply not included) overvoltage will damage the unit

Power Input Interfaces: DC 5.5 high-current jack, 5V positive/negative solder pads and 2-pin terminal

Reverse Polarity Protection (Power Input): Protected against reverse connection, but reverse polarity connection is strictly prohibited

Channel Type: 8 independent channels, each operates independently without interference

Channel Synchronization: Supports synchronized settings across all 8 channels, or individual parameter settings for each channel

Operating Modes Overview:

Auto Mode: Program starts Charges at 4.2V charge cutoff voltage, stops when charge current drops below cutoff current for 30 seconds (first charge complete) Rests (no charge/discharge) Discharges at the set cutoff voltage, stops when load voltage drops below cutoff voltage for 10 seconds (discharge complete) Rests (no charge/discharge) Re-charges at the recharge cutoff voltage. If recharge voltage is set to 4.2V, program ends when charge current drops below cutoff current for 30 seconds. If recharge voltage is not set to 4.2V, program ends when battery voltage reaches the recharge voltage. Recharge complete, program ends Auto Mode cycle finished.

Charge Mode: Program starts When charge voltage is set to 4.2V, program ends when charge current drops below cutoff current for 30 seconds. If charge voltage is not set to 4.2V, program ends when battery voltage reaches the charge voltage Charge complete.

Discharge Mode: Program starts Program ends when load voltage drops below cutoff voltage for 10 seconds Discharge complete.

Activation Mode: For professional use only. Operator must remain present during operation! Performs forced charging at the charge cutoff voltage and does not stop automatically must be manually terminated.

Charge Current: Each channel supports a maximum of approximately 1A (non-constant current), not adjustable.

Charge (Cutoff) Voltage: 6 adjustable levels 3.7V, 3.8V, 3.9V, 4.0V, 4.1V, 4.2V

Recharge (Cutoff) Voltage: 13 adjustable levels 3.0V, 3.1V, 3.2V, 3.3V, 3.4V, 3.5V, 3.6V, 3.7V, 3.8V, 3.9V, 4.0V, 4.1V, 4.2V

Charge Cutoff Current: 3 adjustable levels 100mA, 200mA, 300mA

Discharge Current: Each channel supports a maximum of approximately 1A (non-constant current), not adjustable.

Discharge Cutoff Voltage: 17 adjustable levels 2.0V, 2.1V, 2.2V, 2.3V, 2.4V, 2.5V, 2.6V, 2.7V, 2.8V, 2.9V, 3.0V, 3.1V, 3.2V, 3.3V, 3.4V, 3.5V, 3.6V

Rest Time: Adjustable from 1 to 5 minutes

8-Channel Status Preview: Supports one-screen preview of all 8 channels

Single-Channel Detail Display: Supported

Single-Charge/Discharge Curve Display: Supported

Internal Resistance Measurement: DC two-wire method for internal resistance testing; intended for batch sorting and comparison only

Cooling Method: Active cooling

Overheat Protection: Supported

Charge/Discharge Cycles: Auto mode supports only 1 cycle (charge discharge recharge); does not support multiple cycles

External Testing: Supported via 2-pin terminal for external discharge. Each channel can only support either the battery holder or external testing at one time both cannot be used simultaneously

Battery Reverse Polarity Protection: Protected against reverse battery connection, but reverse polarity battery installation is strictly prohibited
