RACE Series: A New Era of Batteries
Minimized "Vampire Drain"
Traditional lead-acid batteries are a century-old technology, surprisingly found in today’s cutting-edge electric vehicles (EVs). They power 12V systems including onboard computers, wipers, and lights, as these components are designed for older vehicles and are readily available and because of that are not upgraded to be EV-specific.
The 12V battery is drained by many systems working while the car is parked, resulting in a periodical need to charge the 12V battery by draining the main battery. However, lead-acid batteries exhibit significant energy loss during both charging and discharging. Lead-acid batteries will simply consume and lose this energy all the time it is in use.
This is often called the “vampire drain”.
You will notice it as the decrease in the main (traction) battery’s state of charge when parked overnight. For example, the main battery might be at 50% when you leave the car. While the day after it is at a mere 48%.
By upgrading to a modern battery, this drain is substantially reduced.
Enhanced Efficiency Boosts Driving Range
In addition to mitigating the “vampire drain”, described above. The driving range will experience a subtle, yet valuable improvement. In comparison the energy required for propulsion is considerably higher, and minimizing energy wastage in the 12V battery contributes positively to the driving range. The slightly higher voltage will also add to the efficiency.
Reduced Weight
Ensures Agile Acceleration Beyond energy conservation. Reducing the vehicle’s weight significantly enhances its performance, particularly in city traffic characterized by frequent accelerations.
The introduction of lightweight batteries not only contributes to an extended city range but also improves handling and acceleration.
The “Ultra lightweight” range is designed to cater to racing enthusiasts who value swift responsiveness.
Unparalleled Safety
With Triple-Layered Protection & Intelligent Management SUNBEAMsystem, known for crafting market-leading battery solutions for yachts and RVs, ensures optimal safety in its products.
The robust hardware is exceptionally durable, and capable of withstanding extreme conditions like being crushed or exposed to fire without posing any risk.
Coupled with an intelligent protection system, these batteries promise superior safety compared to conventional alternatives, ensuring added security in the event of an accident.
Seamless Transition from Lead-Acid to Modern Batteries
The new batteries are designed to effortlessly replace the original lead-acid units, featuring the same form factor and intelligent internal systems for full compatibility with your vehicle.
SUNBEAMsystem offers comprehensive video guides tailored to each vehicle type, facilitating easy installation. While an experienced installer can complete the transition in 5-10 minutes, even a novice can confidently install the new battery within 30 minutes on their first attempt.
Take a look at our installation videos before you buy.

BETTER FOR THE PLANET
Not only will efficiency increase, and less energy be wasted but also if you make sure your old lead-acid battery is properly recycled, there will be less hazardous lead out there. Rest assured our batteries are all 100% Cobalt free and do not contain any conflict metals.
RANGE EXTENDING TECHNIQUES
The RACE batteries are a part of our efforts to extend the range of modern electrical vehicles. Read more about our Range Extending Spoiler and the wind tunnel testing behind it.
Read the article”Mastering the slipstream, this groundbreaking spoiler shifts its focus from the downforce typical of traditional spoilers, to a relentless pursuit of minimizing aerodynamic resistance.



The Future is Here: Smart Mobile Home
Mobile Smart Home is a free feature in the Multi Connect app that transforms your boat or RV into a smart home. Use a tablet (which can be mounted with our universal wall bracket) as a modern control panel. You can control the system locally, remotely via your mobile, and share access with your family.
- Sleek Control Panel: Use a tablet as your control center.
- Real-Time Monitoring: Share information with your family and remotely control your devices from anywhere (requires an Internet-connected tablet).
- Energy Saving: With Screen Power Saver (PIR), screen energy consumption is minimized.
- Online Statistics: Log in to a personal webpage for real-time updated data.
- Compatible Ecosystem: The app supports a growing range of devices, such as Moonray solar chargers and Smart Switch.
