One of the most common questions about electric vehicles we get asked is:
What happens to their batteries at the end of their life?
Surely, there’s a sustainable solution to this? Enter Fellten Systems. A company redefining the future of battery re-use with an innovative energy storage solution – the Charge Qube.
Giving EV Batteries a Second Life
EV batteries don’t need to expire once they’ve been used in a vehicle. OK, they may no longer be efficient enough for high-performance driving, but many still retain significant energy storage potential for uses such as the charge Qube.
Fellten repurposes batteries from high-mileage or accident-damaged electric vehicles, including Tesla, BMW, Polestar, and BYD models. These batteries undergo rigorous checks to ensure they are still safe and effective before being stacked into the Charge Qube system. The result? A robust energy storage solution capable of holding up to 450 kWh of power. That’s a lot of power by the way.
Does the Charge Cube Work?
Ever been at an outdoor event or festival where power supply is a challenge? Normally, these events rely on diesel generators, which are loud, expensive, and horrendously bad for the environment. The Charge Qube changes the entire game by providing:
✅ Drop-in power solutions for fleets and businesses without the need to invest in expensive grid upgrades.
✅ Sustainable energy storage for events, reducing reliance on pollution-belching generators.
✅ Off-grid EV charging. That’s right! No more limited charging options at temporary locations!!
Instead of expensive grid connections or planning headaches, these units can be deployed quickly, making them absolutely ideal for temporary or semi-permanent locations.
The myenergi Connection: Smart Charging with zappi
Pairing the Charge Qube with our favourite myenergi zappi charger takes sustainable charging to a whole new level. The zappi is a British-built, intelligent EV charger that can be cleverly integrated with solar panels, battery storage, and off-grid solutions like the Charge Qube.
Users can:
Charge their EVs using stored renewable energy, reducing reliance on dirty fossil fuels.
Integrate solar power, even on cloudy UK days, maximising efficiency.
Monitor energy consumption and optimise charging to save those pennies and reduce dependency on the over-stretched grid.
By combining Fellten’s Charge Qube with myenergi’s zappi EV charger, businesses, fleet operators, and event organisers can create epic off-grid, zero-emissions charging solutions that are both cost-effective and sustainable.
A Game-Changer for Fleet Operators
Beyond events, fleet operators stand to benefit massively from this technology. Many fleet depots lack sufficient power infrastructure to support multiple electric vans or lorries. Instead of paying hefty sums to upgrade grid connections, a Charge Qube can store and distribute power efficiently overnight, ensuring that electric fleets are ready to hit the road fully charged and raring to go each day.
Add a zappi charger into the mix, and fleets can automate charging schedules to use stored energy efficiently, ensuring vehicles are ready to go without overloading the grid.
More Than Just Storage – Smart Energy Use
One of the key features of the Charge Qube is its ability to buffer power. The grid doesn’t handle sudden high-energy demands well, such as rapid charging spikes. The Charge Qube smooths this spikiness out by:
✅ Storing energy during off-peak hours and delivering it when demand is high.
✅ Integrating with renewable sources, such as solar panels, for even cleaner, greener charging.
✅ Providing rapid CCS charging, ensuring electric vehicles can be powered up quickly and efficiently.
Even on a typical gloomy UK day, solar panels on-site can still generate up to 10 kW of energy, adding to the sustainability of the set-up.
From Classic Cars to Future Innovations
Fellten is no stranger to battery repurposing. Before developing the Charge Qube, they specialised in retrofitting classic cars, turning beloved classics like Mini Coopers, Porsche’s and Defenders into fully electric vehicles. This expertise in battery integration has made them leaders in the EV energy storage space.
Today, their work extends beyond enthusiasts and into mainstream solutions that can revolutionise the way we think about energy use in EVs.
Who Can Benefit from Charge Qube?
The potential applications of the Charge Cube are enormous! To start with, it’s an ideal solution for:
- Fleet operators needing scalable charging infrastructure.
- Festivals & events looking for clean, silent power alternatives.
- Construction sites requiring temporary, off-grid energy.
- Landlords & businesses avoiding costly grid upgrades.
- Cities with noise pollution regulations restricting generator use.

The Road Ahead
As more EVs hit the road, it’s important to think of how we can continue the sustainability cycle when batteries are at the end of their EV life. Rather than letting valuable batteries sit unused clogging up landfill sites, solutions like the Charge Qube demonstrate that there is life beyond the car. By integrating the myenergi zappi charger, this Second Life energy storage system becomes even more powerful and practical for real-world use.
With their innovative approach, Fellten and myenergi are proving that Second Life energy storage is not just possible but essential for a cleaner, more sustainable future.
