Extended Range and Enhanced Performance: The DRIVE Battery's Latest Leap

Experience up to 4.5 times the range per unit of carried weight with a DRIVE battery, outperforming traditional lead-acid batteries significantly. Our recent advancements in the SMART LITHIUM series have pushed the boundaries even further, offering an impressive 8% increase in capacity for the same battery size. Alongside, we’ve enhanced the current capabilities, boosting both efficiency and reliability dramatically. Central to our series is an unwavering commitment to innovation, highlighted by regular software updates that ensure our technology remains at the forefront of the industry

Exceptional life expectancy and durability

It’s well-known that lithium batteries provide double the usable capacity of lead-acid counterparts, with considerably lower charging and discharging losses. On top of that SMART LITHIUM’s exceptionally durable cells and configuration ensure minimal capacity loss over time—less than 20% after over 5,000 cycles, often significantly less. This durability also extends to winter use and offers greater flexibility with fewer limitations than traditional lithium batteries.

Alternator Friendly High Performance BMS

The Battery Management System (BMS) is designed to be compatible with alternators, but it necessitates the use of a lead-acid starter battery if you’re employing alternator (motor) charging. For those in search of batteries for domestic or household use, our Plug & Play series is highly recommended. This series is specifically designed to ensure the gentle handling of your alternator, offering a unique solution that stands out in the market. On the other hand, when it comes to energy storage for propulsion, the BMS integrated into our DRIVE battery series is unmatched in performance, offering superior capabilities compared to other options available.

Stainless Power Matrix

Tab-less 3270 cells bolted to a steel structure

A key factor in the success of SUNBEAMsystem’s batteries, particularly the Plug & Play series, is our unique construction method, the Stainless Power Matrix. This process requires significantly more time and investment than the industry standard. Unlike typical methods that favor cost-saving measures like soldering or laser welding, soft plastic frames, and the use of prismatic cells, we instead focus on long-term quality. Our commitment is to craft a product that not only performs superiorly but also embodies excellence in every aspect of its design and functionality.

● Cylindrical cells: For our high-performance models like Plug & Play, we exclusively use cylindrical cells which offer several advantages over prismatic cells, such as better heat resistance, heat dissipation, increased mechanical stability, and lifespan.

● Upgraded to 3270 cells: The bolted 3270 cells we use are unique. They are hard to distinguish from ordinary cells by eye, but their larger size is distinctive. We made the switch from smaller cells many years ago, a move now reflected in the car industry where leading manufacturers (e.g., Tesla and Rivian) are working hard to make a similar technological leap by upgrading from smaller 2170 cells to the larger 4680 cells.

● Cells are NOT connected by soldering: The Plug & Play batteries use tab-less cylindrical cells; we avoid connecting the cells with soft tabs as a battery built in this way has an increased risk of failure during shocks and vibrations (even despite laser welding). Such solutions also create a higher electrical resistance between the cells. Higher resistance results in worse efficiency and performance.

● Cells bolted to a steel structure for stability & better conduction: We use a unique construction that is exceptionally robust both physically and electrically. The individual cells are bolted, one by one, to a frame constructed in stainless steel. This makes the battery incredibly robust and shape-retaining, while also providing excellent heat dissipation. Compare this with an industry where reliance on plastic fixation is all too common.

The construction with a stainless, stable structure and bolted cylindrical cells delivers unbeatable quality over time, with numerous positive effects such as exceptional performance and guaranteed enhanced safety.

Winter Mode

A unique feature only available on SUNBEAMsystem batteries

SUNBEAMsystem batteries come with an exclusive and innovative feature: Winter Mode. This unique capability is a testament to the over-engineering of our batteries, designed to operate flawlessly in cold conditions without sustaining damage. Activating Winter Mode is straightforward – simply adjust the setting in the app based on the weather forecast or upon receiving a notification on your phone. This simple action is all it takes from your end.

While Winter Mode doesn’t negate the temporary capacity reduction inherent to cold weather, it does ensure that your battery can be used without resorting to the energy-intensive heaters that other systems rely on. This means you can continue to use your battery efficiently, even in cold temperatures, without the risk of deadlocking or unnecessary power consumption.

Easy Charge Reboot

Overcoming Depletion Challenges with Ease

One of the standout benefits of lithium batteries is their sophisticated Battery Management System (BMS). A fundamental function of any BMS is to disconnect the battery once it’s depleted, a necessary measure to prevent damage. However, this safety feature can become a significant inconvenience, as it also prevents modern chargers from recognizing and charging the battery, leading to a frustrating, and sometimes dangerous, deadlock.

But with the SUNBEAMsystem DRIVE, this issue is effortlessly resolved. Simply open your smartphone, tap on the notification from our dedicated app that links to your battery, and confirm when prompted. This action reactivates the battery’s ability to communicate with the charger, initiating the charging process and closely monitoring the critical initial phase. This straightforward yet innovative solution not only eliminates frustration but also ensures your safety and convenience, truly embodying the principle that sometimes the simplest solutions are the most revolutionary.

The Multi Layered Safety Concept

The answer to why SMART LITHIUM is safer than your old batteries

SUNBEAMsystem’s SMART LITHIUM batteries are designed with an unparalleled safety architecture, distinguishing them from conventional lithium-ion technologies. Here’s how we ensure the highest safety standards:

  1. Advanced Chemistry for Superior Safety
    Unlike traditional lithium-ion batteries, which have been linked to safety incidents, our batteries utilize Lithium Iron Phosphate (LiFePO4) chemistry. This is widely recognized as the safest battery chemistry available, significantly reducing the risk of accidents.
  2. Built-in Fire Safety Valves
    Each cell is equipped with a fire safety valve, a critical safety feature that acts as a last line of defense. In extreme scenarios, such as if the battery were exposed to intense heat or fire, these valves would activate to mitigate any potential hazards, ensuring safety.
  3. Comprehensive Electronic Protection
    Beyond physical safety mechanisms, our batteries are fortified with an advanced electronic protection system. This proactive system not only safeguards the batteries by ensuring they are operated within safe parameters but also responds dynamically to protect against unforeseen incidents.

Certified Safety Under All Conditions

Our batteries are rigorously tested to withstand extreme conditions without sacrificing safety. Their bolted, solder-free rigid layout, along with the preference for cylindrical over prismatic cells, significantly bolsters safety.

Certified Resistance To:

● Penetration, Crushing, Fire
● Repeated Vibrations, Shock Impact
● Short Circuiting, Overcharging

Thanks to these extensive safety features, SUNBEAMsystem’s SMART LITHIUM emerges as one of the market’s safest battery choices. Our commitment to layered safety has granted the SMART LITHIUM series a distinguished air transport certification under UN 38.3 legislation, underscoring its outstanding safety credentials.
