OUR RANGE OF SOLAR BATTERIES
Performance and durability, our solar batteries efficiently store solar energy to power your off-grid equipment, even in adverse weather conditions. Our Belios teams will guide you in selecting our range of batteries best suited to your needs.
Xtreme Batteries
For extreme conditions
Ni-MH technology

The Xtreme batteries use a Ni-MH technology studied for extreme conditions.
They are perfectly adapted to temperatures varying between -25°C and +80°C, compared to a lead battery which cannot withstand temperatures above +40°C.
In addition, Ni-MH technology is distinguished by its resistance to humid and marine environments.
LongLife batteries
For a longer life
LiFePO4 technology

The Longlife batteries use the lithium LiFePO4, the most efficient technology in the solar energy sector.
This lithium technology has an energy density 3 times greater than that of a lead battery.
The lifetime of an Longlife battery is 10 times higher than that of lead, without loss of performance.
Our range of batteries does not meet your needs?
LET’S DEVELOP YOUR CUSTOM SOLAR BATTERY
Belios® solar batteries can be custom designed to meet your specific requirements. Our R&D center will help you design and choose the battery technology that best suits your needs.

Innovative solar batteries

Is the case not suitable for your installation?
The battery and the electronic part can be supplied without the mechanical case to integrate them in your own box or in an installation like a mast. The Belios teams assist you in the integration of the system, especially for the thermal part.
Our engineers can also take care of the design of a custom-made mechanical casing to perfectly match your needs and your off-grid equipment.
