Up-Stealth 'living hinge' with PowerGenix Nickel-Zinc battery packs
828 PowerGenix, a manufacturer of high-performance, rechargeable Nickel-Zinc (NiZn) batteries, has announced an exclusive agreement with 829 PSI Acquisition to supply battery cells for UP-Stealth, a cutting-edge uninterruptible power supply (UPS) for the traffic industry.

Using the high power and small size of PowerGenix NiZn battery cells, the UP-Stealth system is a smaller and lighter package than lead-acid equivalents. The partners say that UP-Stealth can be installed in previously unutilised space in existing traffic control cabinets, replacing traditional lead-acid-based UPS systems and eliminating the bulky, heavy external battery cabinet attached to the primary traffic cabinet.

Compared to the current leadacid standard, the PowerGenix-PSI solution is about 70 per cent lighter, with a much longer service life and requires no maintenance. NiZn batteries are also recyclable and RoHS compliant, with no toxic heavy metals, providing an environmentally friendly alternative to lead-acid and other battery chemistries.

    Since 1984, Q-Free has been a leader in tolling solutions, and now the company is driving innovation in road user charging (RUC) — a smarter, more flexible way to pay for road usage. Unlike traditional tolling, RUC calculates fees based on distance driven, with dynamic pricing for factors like rush hour congestion or urban vs rural travel. It also shifts revenue focus, covering external costs like accidents, noise, and delays rather than just infrastructure.
