Battery pack only.
Evidence that travels with it.
Bring us an EV or hybrid high-voltage battery pack for an off-vehicle assessment. We identify the physical pack, record the available electrical and diagnostic evidence, and issue a clear certificate linked to its part number, serial number and photographs.
OFF-VEHICLE PACK TEST

What the service records
A certificate for the battery, without pretending the vehicle is present.
The test record is built around the loose pack and the evidence available on the bench. Vehicle registration and donor VIN can be added when known, but they are not required to identify or certificate the battery.
Measured evidence
Available pack voltage, SOC, SOH, capacity evidence, insulation and resistance readings, module spread, temperature data and recorded test conditions.
Diagnostic observations
Available BMS communication, fault codes, contactor and pre-charge observations, cooling or leak checks, and charge/discharge test results.
From intake to a traceable certificate.
Every result keeps the identity, custody and limitations of the tested pack visible.
Send details first
Tell us the part number, serial number, origin, present condition and why the pack needs testing.
Agree safe intake
We review the condition and agree how the battery can be received before it is moved.
Inspect and test
A competent technician records the applicable checks, equipment, conditions and limitations.
Receive evidence
You receive a viewable and printable certificate linked to the photographed pack and rating label.
Do not deliver, courier or ship a high-voltage battery without speaking to us first.
Loose lithium batteries can require specific dangerous-goods classification, packaging, documentation and transport arrangements. Damaged, leaking, swollen, overheated or otherwise suspect packs need particular precautions. Do not open, energise or attempt to test a pack unless you are trained and equipped for that work.

Useful before repair or reuse
Record condition before deeper diagnosis, module work, sale, reuse planning or a decision about whether further investigation is worthwhile.
Clear limits
An off-vehicle result is not a roadworthiness test and does not automatically confirm compatibility, installation suitability, transport status, warranty or future life.
Evidence for trade and owners
A consistent record for battery owners, repairers, dismantlers, insurers, workshops and other businesses handling a known pack.
Questions about offline battery testing
Do I need the car or registration?
No. This service is designed for a battery pack outside the vehicle. Known donor details help provide context, but the certificate identifies the pack using its own markings and photographs.
Does every battery allow every test?
No. Access, BMS communication, state, connector condition, manufacturer information and safe operating limits vary. The certificate records what was tested and any limitations.
Does a pass mean the pack can be fitted to any vehicle?
No. Compatibility, programming, mechanical condition, installation requirements and manufacturer procedures are separate matters.
Can I simply send the pack by courier?
Please contact us first. Transport requirements depend on battery type and condition, and damaged or defective lithium batteries can require special arrangements.
Start with the battery’s identity and condition.
Email clear photographs of the complete pack and rating label, plus the part number, serial number, known origin and any faults or damage. We will discuss the appropriate next step and intake arrangements.
