2-Channel 18650 Battery Tester – Capacity & Internal Resistance
This tester supports two independent channels for measuring the capacity and internal resistance of lithium batteries (Li-ion, LiFePO4, LTO). Each channel can be charged and discharged separately, with up to nine charge/discharge cycles in automatic mode. It features a sturdy battery clip and a compact holder for 18650 and flat batteries.
The dedicated battery charging chip allows for a maximum charging current of approximately 1A at a full voltage of 4.2V, with automatic shut-off at a charging current of <0.1A. The discharge current is up to 1A, with automatic shutdown upon reaching the set stop voltage (2.5–3.5V, adjustable in 11 steps). Active cooling via a fan prevents overheating.
Easy to use: Switch channels, check internal resistance, start charging and discharging, measure capacity, and perform cycles. Powered by a DC 5V Type-C power supply (power adapter included), system language is English, and it saves setup parameters. Ideal for labs, hobbyists, or workshops, for precise battery testing and maintenance.
Package includes: 1 x 2-channel battery tester (batteries not included).
4-Channel 18650 Battery Tester – Capacity & Internal Resistance
This tester supports 4 independent channels for measuring the capacity and internal resistance of lithium batteries (Li-ion, LTO, not LiFePO4). Each channel can be charged and discharged separately, up to 9 charge/discharge cycles in automatic mode. A sturdy battery clip and compact holder allow for testing of 18650 and flat batteries.
The dedicated battery charging chip provides a maximum charging current of approximately 1A at a full voltage of 4.2V, with automatic shut-off at a charging current of <0.1A. Discharge current is up to 1A, with automatic shutdown upon reaching the set stop voltage (2.5–3.5V, 11 adjustable levels). Active fan cooling prevents overheating.
Easy to use: Switch channels, check internal resistance, start charge/discharge, measure capacity, and run cycles. DC 5V Type-C power supply (power adapter included), system language English, saves setup parameters. Ideal for labs, workshops, or hobbyists for precise battery testing and maintenance.
Package includes: 1 x 4-channel battery tester (batteries not included).
8-Channel 18650 Battery Tester – Capacity & Internal Resistance
This tester supports 8 independent channels for measuring the capacity and internal resistance of lithium batteries (Li-ion, LTO; not LiFePO4). Each channel can be operated separately without interfering with other channels and supports automatic charge/discharge cycles. A sturdy battery clip and compact holder allow for testing of 18650 and flat batteries.
Real-time voltage and current waveform display, DC two-wire method for internal resistance measurement. Dedicated battery charging chip control, maximum charging current approx. 1A, full voltage 4.2V, automatic shut-off at charging current <0.1A. Discharge current up to 1A, automatic shut-off at adjustable stop voltage (2.0–3.6V, 17 levels). Active fan cooling and overheat protection ensure safe operation.
Easy operation: Switch channels, display individual channel charge/discharge curves, check internal resistance, measure capacity. DC 5V high-current power supply, system language English, saves setup parameters. Ideal for laboratory, workshop, or hobby use for precise battery testing and maintenance.
