"Commenting on potential further opportunities, PPK Group Ltd Executive Chairman Robin Levison also added: “...I see this unique ‘electrification project’ as the first step on a broader collaboration opportunity between Ampcontrol, PPK Group and our subsidiary company LIS Energy Ltd. LIS Energy continues to commercialise its proprietary lithium sulphur battery technology through its joint venture research agreement with Deakin University; we are very enthusiastic about the potential future opportunities this project could present.”
