Pick the cell-testing line from a broad catalogue
NEBULA's official site groups its cell, module, PACK, BMS and EOL test instruments apart from intelligent production equipment, charging systems and energy products. The registered company is 福建星云电子股份有限公司 in Fuzhou. When you specify a cell cycler, keep the order inside the cell-testing line.
A May 2026 report from the Fujian industry department names the company in a piece on corporate growth and investment support. It is a dated public reference for who the company is. Electrical accuracy and suitability for your cell chemistry come from the instrument specification and your own acceptance test.
What a 12 V, 300 A channel is for
A channel rated to 300 A at up to 12 V suits large single cells or small groups. Typical jobs are high-rate discharge, pulse power tests and capacity checks on automotive cells. With a bipolar range, the channel can push a cell slightly below zero volts for special tests, which an ordinary cycler cannot do. A 300 A range is less precise at low current, so small cells usually go on a separate instrument.
The NEBULA catalogue runs from cell, module, pack and BMS testers to end-of-line testers, production equipment, charging systems and energy products, and a subsidiary offers testing services. The battery tester page shows how to read ranges and accuracy for a cell tester. The cell measurement page explains the DCIR pulse tests that buyers often use a channel like this for.

The featured instrument is the 12V300A cell charging and discharging test system. Its page covers the bipolar voltage range, the dynamic-response figures and the independent channels, and how to specify each one for your cells.
Set the battery-testing scope of the order
NEBULA's company introduction places battery testing equipment and intelligent manufacturing solutions in one group, and energy-storage converters, charging equipment and related services in another. A subsidiary provides testing services. If you want lab testing or a certificate, contract it as a separate service with its own scope.
For the test equipment itself, state the electrical conditions and channel count your cell, module or PACK needs. Ask which measurement, control and reporting functions come with the instrument, what calibration documents will be delivered, and whether any outside testing is offered as a separately priced service.
