CT5003AK 5V300A battery tester
The LAND CT5003AK 5V300A is a power-battery cell tester in Wuhan LAND's energy-saving CT500 series. Its name gives 5 V and 300 A, which suits large-format cells and high-current pulse work; ranges, channels and accuracy come from the model datasheet.

What the model name tells you
LAND's energy-saving power-battery category lists the CT5003AK 5V300A next to other CT500-series models. The name gives five volts and 300 A. The category page lists no minimum current, accuracy formula, channel count, power envelope or limits on running channels together.
Ask for the model's current datasheet before comparing it with a multi-range or independent-channel system. If energy saving matters to your budget, ask LAND for measured conversion efficiency and the expected energy use on your test programme.
| Parameter | Published value | Record status |
|---|---|---|
| Model designation | CT5003AK 5V300A | known |
| Official category | Energy-saving power-battery testing | known |
| Application boundary | Cell testing; separate from a complete PACK manufacturing line | known |
Catalogue values apply to the configuration and test method the maker states. Ask for the values that apply to your configuration.

Send the test programme first
Give the cell voltage limits, charge/discharge currents, dynamic steps and the number of channels you will run at once. Ask for the measurement ranges and calibration conditions at those operating points. Describe your fixtures and cables so connection effects are considered along with the instrument.
Check the software version, the exported data fields and what happens after a power or network interruption. If temperature equipment is part of the order, find out how it connects and how its readings are synchronised with the cell record. Ask LAND for a sample test file and a calibration report for the model.

Keep range, connection and data settings together
Ask for a controlled specification of your exact CT5003AK configuration, covering current and voltage ranges, uncertainty and any limits that depend on the connection. The model name identifies the unit, and that sheet defines it. Before comparing offers, list your smallest current, planned endpoints and timing needs.
Check the operating points that matter with calibrated references and an agreed programme. Open an exported test and look at step transitions, time stamps, range changes and interruption markers. Store channel, fixture, cable, software version and temperature details with each file so later analysis can tell a set-up change from a cell effect. Ask how incomplete runs are recovered or closed off.
Buying guidance from BatteryEquip.
Agree the operating envelope and recovery duties together
Ask for a current CT5003AK datasheet that links voltage, current and power to the number of channels running at once. In the same proposal, state cable and fixture ratings, where sense leads are placed and the data-saving interval you need. The model name gives neither channel count nor accuracy formula.
For long tests, agree what happens to the sequence and data after a power or communication interruption and who helps recover them. LAND's service page explains how to arrange support; put response times for this model in a service agreement. The university CT3002A purchase is a separate model with its own calibration, power envelope and commercial terms.
LAND's profile lists its micro-current and high-current tester families, and the cell measurement page explains the DCIR pulse tests that a 300 A channel is often used for.
Questions that change the purchase
| Decision | What the catalogue says | Next step |
|---|---|---|
| Which electrical range supports the experiment? | The category page gives the model name with 5 V and 300 A and no range table. | Ask for the channel specification and calibration conditions. |
| Does the programme survive the real connection? | The page gives no fixture, cable or recording details. | Run the required steps and keep an export linked to the configuration. |
Equipment questions
Is 300 A available at every test voltage?
The name does not say. Ask for a voltage and current schedule and the limits for running channels together on this exact model.
Source s2Does this reference supply a PACK manufacturing line?
No. It is a cell tester. PACK assembly, BMS integration and PACK EOL testing need separate equipment.
