This rechargeable battery case set includes 8 lithium LiFePO4 4R25 batteries designed primarily for road traffic lamps but obviously have uses for other compatible devices that rely on a long life lantern style battery. The batteries can be charged in situ within their robust carry case, using either UK mains power or an in‑vehicle charging adapter.
A full case of eight batteries can be recharged simultaneously within 2–3 hours, providing a highly efficient and cost‑effective power solution for traffic management operators.
Significant Cost Savings & Green Credentials
This rechargeable system offers substantial long‑term savings compared to disposable 4R25 batteries. By switching to renewable power, operators reduce waste, lower operational costs, and improve environmental performance — an advantage for contract tenders and sustainability commitments.
LiFePO4 4R25 Battery Specification
Each battery is a LiFePO4 6V 8000mAh unit with a micro‑C charging port and a four‑bar LED charge indicator that illuminates green during charging.
A built‑in power status button allows operators to check individual battery charge levels — a feature rarely seen on rechargeable batteries in the 4R25 format.
Robust Charging Case
The charging case features a weather‑resistant charging port and includes both a UK mains adapter and an in‑vehicle charging adapter as standard. The case can fully recharge all eight batteries within 2–3 hours.
Proprietary Charging Cables
The charging cables are unique to this system. In the event of theft, batteries cannot be charged using third‑party cables — only the supplied proprietary cable will work. This acts as a deterrent against misappropriation.
For security reasons, we only supply replacement cables to customers who have previously purchased this product.
Long-Term Cost Efficiency
These lithium batteries are designed for up to 500 recharge cycles. Operators who frequently replace disposable 4R25 batteries can achieve a return on investment within 3–4 months.
Example Cost Comparison
If a standard 4R25 battery costs £6.00 and is replaced four times per month, that equates to:
- £72.00 per year per lamp
- £216.00 over three years
- £1,728.00 for eight lamps over three years
In comparison, a case set of eight rechargeable batteries costing under £360.00 can save operators up to £1,378.00 over the same period.
Recharging costs are minimal — typically pennies per week — making this system an extremely cost‑effective long‑term solution.
Renewable Power for Modern Traffic Management
Switching to rechargeable power supports both financial efficiency and environmental responsibility. These benefits are increasingly important for organisations seeking to improve sustainability and win competitive contracts.
Combine with Solar-Assisted Road Lamps
Alongside the rechargeable battery case set, we have released a range of solar‑assisted road lamps. These lamps feature large, high‑efficiency solar panels that provide up to 800mA of charging power.
During summer months, some models become almost self‑sufficient, activating only in low light and requiring significantly fewer battery changes. In testing, maintenance intervals were reduced by up to 45%.
This combination of rechargeable batteries and solar‑assisted lamps offers major labour savings, reduced transport disruption, and improved operational efficiency.
Cost Effective – Significantly better value than disposable lantern battery types
Technically advanced – LED 4 bar status indicator, recharge when using solar panel lamps
Fast recharging 8 batteries in 2-3 hours
Robust carry case with built in charging capability – charge 8 batteries simultaneously
