We are 247

247 distributes disruptive energy storage solutions.

Revolutionary energy storage technology.

Current Lithium-Ion batteries have limitations that make it difficult and often unsafe to use in domestic applications or have a weak return-on-investment. The energy storage devices we sell are therefore based on capacitors.  Sustainable and safe supercapacitors and an intelligent software layer.

The capacitor goes back to 1782 (Mr Alessandro Volta called it a condenser) and sits nowadays on many electronic boards. Solid-state capacitors have a very long life and have little dependency on vibration or ambient temperature. Our energy storage units are using supercapacitors in large quantities. Our supercapacitors can store 100x more energy per unit mass than electrolytic capacitors. They accept and deliver charge much faster than batteries and tolerates many more charge and discharge cycles than rechargeable batteries (based on lithium-ion). Hence we sell a battery that is no battery and performs way better than any battery (patented technology).

247 offers long lifespan energy storage device

We warrant 10.000 cycles (or 10 years) but projected lifetime is up to 50.000 cycles. This is possible thanks to the use of supercapacitors versus lithium-ion. It is proven? Capacitors are older than any battery invented and sit on millions of electronic boards. 

Up to 20x faster charging than Li-Ion

Charge a battery from 0% tot 100%, with the right power supply we can do it in 6 minutes.

Does not burn or explode

Because of the supercapacitors used in our energy storage devices, there is no risk of overheating or burning since capacitors generate far less heat and are less sensitive to ambient temperature. 

Slow degradation over time

Supercapacitors show slower degradation of capacity and efficiency over life-time. 

Form factor similar to Li-Ion batteries

Easy to integrate in existing lithium-ion powered solutions and available in different form factors (from small 1kW to 10.000kW).  

Operates -20°C to 55°C

Our energy storage can operate safely between -20°C to 55°C.

DC to DC roundtrip efficiency 97-98%, monthy self-discharge 2-3%

high efficiency 97-98%

low self-discharge limited to 2-3%.

We generate and store your energy.
