RACE Series: A New Era of Batteries

Lightweight and compact

superior replacements for lead-acid batteries

Super Long Life 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.


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.

Smart Mobile Home


Convenience at your fingertips

SUNBEAMsystem is at the forefront of delivering bespoke, state-of-the-art lithium batteries specifically designed for leisure yachts. Our batteries boast unparalleled physical advantages, coupled with an innovative APP connection that allows users to access in-depth information about their battery’s performance.

The same app integrates a variety of smart functions tailored for various vessels, including yachts and RVs. It features our bespoke Mobile Smart Home functionality, enhancing the user experience by providing seamless control and monitoring of their vessel’s systems.

Whether you own a yacht, car, or RV, our app makes it effortless to add and manage your various vessels. It enables you to seamlessly connect to the nearest vessel, ensuring easy access whenever needed. Additionally, if your yacht or RV is equipped with our Mobile Smart Home setup (complete with a SIM card), you can conveniently monitor and control your vessel from a distance via the Internet.

About Our SMART LITHIUM RACE Batteries

Which electric car models are these batteries compatible with?

The SMART LITHIUM Batteries in the RACE Series are designed to be compatible with specific electric car models. Currently, they are available for Polestar 2, Tesla Model S (2012 to 2020), and Tesla Model 3. These batteries serve as direct replacements for the original 12V lead-acid batteries found in these vehicles.

What are the key advantages of SMART LITHIUM Batteries over lead-acid batteries?

Upgrading from traditional lead-acid batteries to SMART LITHIUM batteries offers numerous compelling advantages, including:

  • AVOID “12V BATTERY REPLACEMENT WARNINGS” AND UNRESPONSIVE VEHICLES: Say goodbye to the frustration of a dead battery leaving your vehicle unresponsive.
  • EXTENDED LIFESPAN: SMART LITHIUM batteries last 4-5 times longer than their lead-acid counterparts, ensuring long-term reliability.
  • ENHANCED EFFICIENCY: Experience higher charge/discharge efficiency, resulting in a slightly longer range and, most importantly, minimal “vampire drain” while your vehicle is parked.
  • INCREASED SAFETY: SMART LITHIUM batteries feature onboard computers that can swiftly cut off power in the event of a severe accident, providing an additional layer of security.
  • SIGNIFICANTLY REDUCED WEIGHT: Shed the excess weight of traditional lead-acid batteries, contributing to improved efficiency and handling.
  • ECO-FRIENDLY AND SUSTAINABLE: Opt for our planet-friendly lithium phosphate batteries, which are cobalt-free and have a significantly lower environmental impact. Additionally, you can significantly reduce replacement waste.
