Battery Manufacturing Equipment12V300A cell charging and discharging test system
The NEBULA 12V300A is a bipolar cell charge and discharge tester with ±12 V output, ±0.02% F.S. voltage and current accuracy and 16 independent parallel channels. It suits high-current pulse and drive-profile testing of large cells, with a 2.5 ms current response and 10 ms road-profile simulation.

12V300A: bipolar output, accuracy and timing
NEBULA's product page lists ±12 V output, voltage and current accuracy of ±0.02% F.S., 16 independent parallel channels and offline operation. It gives a current response of 2.5 ms or less, 10 ms road-profile simulation and ripple-superposition simulation. Each timing figure belongs to a different function, and none of them is a recording rate.
The 300 A figure comes from the product name. Ask for the full current-range and power schedule for the configuration you order. Because the accuracy is stated against full scale, the error at a small reading is larger in relative terms. Request the measurement ranges, temperature conditions and calibration certificates at your low-current and high-current operating points.
| Parameter | Published value | Record status |
|---|---|---|
| Published output range | ±12 V | known |
| Published voltage/current accuracy | ±0.02% F.S.; catalogue statement | known |
| Channel arrangement | 16 independent parallel channels; offline operation supported | known |
Catalogue values apply to the configuration and test method the maker states. Ask for the values that apply to your configuration.

See your dynamic programme run, with the saved data
Send the voltage window, currents, waveform and stop conditions you need. Ask NEBULA to run that exact profile on the proposed cell fixture and hand over exported, time-stamped data. Look at command timing, measured response and saved-data resolution one at a time.
The page mentions linkage to external equipment and 24-hour offline operation. Check which interface is supported, how events are synchronised and how records are recovered once communication comes back. If your lab runs for longer stretches, ask how the test system behaves beyond the 24-hour offline window.

Check the programme at the lowest current you will use
Pick the low-current and high-current points that matter for your experiment. Ask for calibration certificates and uncertainty at those points, stating the full-scale basis and operating conditions. A check at top current tells you little about small signals, so include the low end. Keep a note of the fixtures and cable layout with each measurement.
Run the planned sequence in a demonstration approved by NEBULA and go through the exported data. Treat electrical settling, programme step timing and the saved-record interval as three separate results. If channels must run together, note which operating points were applied at the same time. Keep the interruption and restart logs, so an incomplete test can be spotted later in analysis. The aim is repeatable data from an agreed programme, with accuracy and logging rates stated for the ranges you actually use.

Order the instrument as its own scope
NEBULA runs several businesses, described in its company introduction. For this battery test system, settle the electrical configuration, the reporting functions and the calibration documents. If you also want a lab testing service or other energy equipment, name it in the contract as a separate line.
High-current channels like these are often bought for DCIR pulse tests, which the cell measurement page explains.

Questions that change the purchase
| Decision | What the catalogue says | Next step |
|---|---|---|
| Is low-current accuracy sufficient? | The page gives ±0.02% F.S. for voltage and current, stated against full scale. | Ask for range-specific uncertainty at the lowest current you will test. |
| Which timing reaches the exported file? | The page lists a 2.5 ms current response and 10 ms profile simulation, with no saved-record interval. | Run your pulse or cycle sequence in a demonstration and check the time stamps. |
Equipment questions
Is the 10 ms profile entry the same as 2.5 ms data logging?
No. Profile timing and current response are listed as separate items. Ask NEBULA to state the recording interval and synchronisation method in writing.
Source s2Will it suit solid-state or sodium-ion cells?
NEBULA names these applications. For your own cell, set the electrical limits, fixture, programme and safety arrangements, and prove them in a trial run on that cell before you sign off.
