VANCOUVER, British Columbia – May 30, 2025 – Battery X Metals Inc.
(CSE:BATX)(OTCQB:BATXF)(FSE:5YW, WKN:A40X9W) (“Battery X Metals” or the “Company”) an energy
transition resource exploration and technology company, announces that, further to its news release
dated May 2, 2025 confirming the delivery of its second-generation, patent-pending lithium-ion battery
rebalancing machine (“Prototype 2.0”) by its wholly owned subsidiary Battery X Rebalancing Technologies
Inc. (“Battery X Rebalancing Technologies”), and its news releases dated May 23, 2025 and May 27, 2025,
regarding expanded development efforts to achieve compatibility with the Nissan Leaf —the second most
common out-of-warranty electric vehicle (EV) in the United States— Battery X Rebalancing Technologies
has achieved full capacity recovery in a preliminary trial (the “ Trial”) on a retired real-world imbalanced
96-cell Nissan Leaf battery pack, composed of lithium manganese oxide (LMO) and lithium nickel oxide
(LNO) materials (the “Nissan Leaf Battery Pack”).
The Trial results (the “Results”) were performed using Prototype 2.0 on the Nissan Leaf Battery Pack, The
Nissan Leaf Battery Pack was first charged at 12 amperes using Battery X Rebalancing Technologies’ cycling
module to simulate a standard electric vehicle charging cycle. Once the first cell reached the voltage target
of 4.20 volts (the “ Voltage Target ”), a rebalancing current between 0 and 3 amperes was applied
individually to the remaining cells until all 96-battery cells successfully reached the Voltage Target. The
Voltage Target lies within the standard operating range for LMO and LNO lithium-ion cells of 3.0 volts to
4.20 volts, with 4.20 volts commonly recognized as the full capacity in the industry¹.
According to the diagnostic report provided by the vendor of the Nissan Leaf Battery Pack (the “ Battery
Vendor Diagnostic Report ”), the reported measured effective ampere-hour capacity of the Nissan Leaf
Battery Pack prior to rebalancing was 50.34 ampere-hours (Ah). This served as the baseline capacity for
2
the Trial. Following the Trial, Prototype 2.0’s integrated software determined that 1.95 Ah of additional
capacity had been successfully restored. While the Battery Vendor Diagnostic Report did not
quantitatively indicate a loss of capacity, it indicated that the Nissan Leaf Battery Pack was operating at
50.34 Ah with minor voltage imbalance that placed the voltage below the Voltage Target. Rebalancing the
cells to the Voltage Target achieved a 3.9 percent improvement in usable capacity.
The restored 1.95 Ah corresponds to the full theoretical rebalancing increase based on the Voltage Target
achieved, and represents full recovery of the minor voltage imbalance indicated on the Battery Vendor
Diagnostic Report. These results were determined by the Trial based on achieving the Voltage Target
across all 96-battery cells, along with a software feature of Prototype 2.0 that shows the ampere-hours
(Ah) capacity restored through rebalancing for each individual cell, with the largest discrepancy being 1.95
Ah, based on the Voltage Target. Battery X Rebalancing Technologies interprets this result as confirmation
of Prototype 2.0’s ability to restore all imbalance-induced lost capacity through precise voltage alignment
and battery-cell level rebalancing.

Next Steps
To further validate the Results, the Battery X Rebalancing Technologies intends to conduct further trials
to complete a full charge/discharge cycle to empirically confirm whether the 50.34 ampere-hour capacity
reported in the Battery Vendor Diagnostic Report remains consistent following rebalancing. Given that all
96-battery cells have been rebalanced to the Voltage Target, Battery X Rebalancing Technologies does not
anticipate any material variance, and remains confident in its ability to restore all imbalance-induced lost
capacity through precise voltage alignment and battery-cell level rebalancing on the Nissan Leaf Battery
Pack. However, this process will provide definitive confirmation.
Additionally, the full charge/discharge cycle will help identify any potentially defective battery cells within
the pack that may require replacement. While there is currently no indication of any defective cells, this
diagnostic step will serve as a further safeguard in confirming the measured effective ampere-hour
capacity stated in the Battery Vendor Diagnostic Report.
Battery X Rebalancing Technologies continues to rely on the Battery Vendor Diagnostic Report as a
credible third-party baseline and has no reason to believe it is inaccurate. Nevertheless, Battery X
Rebalancing Technologies plans to validate the report through its own independent testing protocols to
ensure accuracy.

Developing Next-Generation Technologies to Support Lithium-Ion Battery Longevity
“This Trial marks a significant milestone in validating Battery X Rebalancing Technologies’ technology
under real-world conditions,” said Massimo Bellini Bressi, CEO of Battery X Metals. “Even with a relatively
well-balanced Nissan Leaf battery pack, the system was able to recover nearly 2 ampere-hours of capacity
— an improvement that underscores the precision and potential of our patent-pending lithium-ion
rebalancing solution. As we expand testing to more aged and imbalanced battery packs, we expect to
identify greater capacity losses that this technology is specifically designed to address. This is just the
beginning of what battery rebalancing can offer the EV ecosystem — extending battery life, improving
performance, and reducing waste.”
As disclosed in the Company’s May 9, 2025 news release, Battery X Rebalancing Technologies entered
into a non-commercial, collaborative scope of services agreement (the “Factor E Agreement”) with Factor
E Motors, an automobile service centre specializing in out-of-warranty Tesla vehicles. The collaboration is
focused on advancing the Company’s patent-pending rebalancing software and hardware, with initial
efforts targeting Tesla Model 3 and Model X battery packs in Factor E’s possession.
Further to the Company’s May 23, 2025 news release, development efforts were expanded to include
functionality for the Nissan Leaf—the second most common out-of-warranty EV model in the United
States. The Results were attained from Trials performed on the Nissan Leaf Battery Pack acquired from an
arm’s-length third party for $1,120.
The Trial was performed in collaboration with Factor E Motors, and in addition to conducting a full
charge/discharge cycle to empirically confirm the Battery Vendor Diagnostic Report, Battery X
Rebalancing Technologies’ is now focused on ongoing validation of standard operating procedures (SOPs)
and post-rebalancing processes. This includes conducting pre- and post-rebalancing diagnostics and
supporting the execution of the rebalancing process. These efforts are intended to refine commercial
workflows and further enhance Battery X Rebalancing Technologies’ proprietary rebalancing technology
in preparation for broader deployment.
These Results mark a critical step in validating system compatibility across diverse battery chemistries and
configurations, particularly in high-volume EV models nearing or beyond the end of their manufacturer
warranties. Management believes the Results demonstrate both the technical effectiveness and
commercial potential of the Battery X Rebalancing Technologies’ patent-pending rebalancing platform. By
validating the restoration of aging battery packs across multiple EV platforms, Battery X Rebalancing
Technologies aims to pioneer a new market segment focused on extending battery life, enhancing
performance, and reducing costly replacements, contributing to a more sustainable electric mobility
future.
Building on the preliminary success of this Trial, Battery X Rebalancing Technologies is preparing to test
its rebalancing technology across a wider variety of battery chemistries, configurations, and real-world
high-volume electric vehicle models.1
