Small black rectangular tester with two vertical 18650 battery slots and dual Type-C ports

Shutao 2-Channel 18650 Battery Capacity Tester with Internal Resistance Test

SKU CH-N849-P6RAJ

Tests two 18650 cells simultaneously with automatic charge-discharge cycles and internal resistance measurement

  • Team affiliation1 Piece
  • Key featuresBattery capacity tester module, false
  • Simultaneously test two 18650 cells independently for fast health assessment
  • Automatic charge-discharge cycles up to five times revitalise and maximise capacity
  • DC two-wire method measures internal resistance for accurate reference values
  • Eleven selectable stop-discharge voltages from 2.5V to 3.5V suit different cell needs
  • Dual Type-C power inputs with overheating protection ensure reliable and safe operation

2-Channel 18650 Battery Analyser

The Shutao tester measures capacity and internal resistance on two independent channels simultaneously. It accepts flat-top 18650 cells and runs fully automatic charge-discharge sequences without user intervention. The unit is powered through dual Type-C inputs and includes both adapter and cable in the box.

Sustained-load behaviour

Automatic protection stops charging at 4.2 V and halts discharge at a selectable level between 2.5 V and 3.5 V across 11 steps. Active cooling and overheating protection keep the module stable during repeated cycles. Up to nine consecutive charge-discharge passes can be programmed to refresh aged cells.

Upgrade path

Replaces single-slot testers that require manual switching and lack internal-resistance readings. The jump is worthwhile when you regularly sort batches of flat-top 18650 cells for power banks, RC packs or household devices and need parallel throughput with built-in safety cut-offs.

Questions about this item

How hot does the Shutao 2-channel tester get when running both channels all day?

The unit includes overheating protection and active cooling to manage temperature during extended use, automatically cutting power if it gets too hot.

What power adapter do I need to supply the dual Type-C inputs?

A DC 5 V USB-C power adapter is required; the package includes the cable but the adapter itself is not supplied.

Will this tester work with the flat-top 18650 cells I already have that charge to 4.2 V?

Yes, it supports flat-top 18650 batteries with a 4.2 V charge voltage and adjustable discharge stop points from 2.5 V to 3.5 V.
