The SMART LITHIUM – Plug & Play Series

A truly smart and state-of-the-art battery, packed with the latest features and the safest and most powerful LiFePO4 technology.
A true drop-in replacement for your outdated lead-acid batteries.

Since its debut in 2016, the SMART LITHIUM Plug & Play series has set the standard for those desiring a seamless, do-it-yourself battery upgrade. We’re continuously innovating: both the hardware and software have received annual enhancements to ensure peak performance and compatibility.

The recent enhancements across the SMART LITHIUM series mark a significant leap forward, with an 8% increase in capacity and improved current capabilities enhancing both efficiency and reliability. At the heart of the series lies a commitment to continuous advancement, underscored by frequent software updates.

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 (but often significantly less). This durability also extends to winter use and offers greater flexibility with fewer limitations than traditional lithium batteries. Such unparalleled robustness is why we confidently refer to it as Plug & Play, setting a new standard in battery technology and user convenience.

Seamless Upgrade

Our Plug & Play series provides an effortless DROP-IN solution to replace any old-style battery. Designed to mimic lead-acid characteristics, it’s Alternator Friendly, ensuring compatibility without the need for additional equipment or complex alterations. SUNBEAMsystem SMART LITHIUM is crafted from the ground up to simplify your upgrade process. We ensure a straightforward replacement experience when you maintain your starter battery and switch your domestic batteries to SMART LITHIUM Plug & Play, making it an easy upgrade for everyone.

Quick Charge

Super Quick Charge enables the ONE to reach 90% charge in under 30 minutes. MULTI can be charged in half of that time, still very fast. Multi stands unrivaled in the market for those needing multiple batteries in their domestic battery bank. A wide temperature usage range and an extended lifetime ensure enhanced usability. The unique Plug & Play feature guarantees compatibility with older equipment, including gentle handling of your alternator. This series delivers unmatched performance and convenience.

Tab-less 32700 Cylindrical 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 in High-Performance Models: Our Plug & Play series uses cylindrical cells for superior heat resistance, stability, and lifespan compared to prismatic cells.

Upgraded to 32700 Cells: We’ve transitioned to larger 32700 cells, similar to advancements in the automotive industry by companies like Tesla and Rivian. These cells enhance performance due to their size and improved capabilities.

No Soldering Connections: Our batteries feature tab-less cylindrical cells connected without soldering, reducing failure risks from shocks and enhancing efficiency by lowering electrical resistance.

Bolted to Steel for Enhanced Stability: Each cell is bolted to a stainless steel frame, ensuring exceptional physical and electrical robustness, optimal shape retention, and excellent heat dissipation, unlike common plastic fixations.

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.

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. Our batteries are rigorously tested to withstand extreme conditions without sacrificing safety. Here’s how we ensure the highest safety standards:

  1. Advanced Safety Chemistry: Our batteries use Lithium Iron Phosphate (LiFePO4) chemistry, recognized for its superior safety profile compared to traditional lithium-ion batteries, greatly minimizing accident risks.
  2. Built-in Fire Safety Valves: Each cell includes a fire safety valve that acts as a crucial defense mechanism. In extreme conditions like intense heat or fire, these valves activate to prevent potential hazards, enhancing safety.
  3. Comprehensive Electronic Protection: Our batteries are equipped with an advanced electronic protection system that ensures operation within safe parameters and dynamically responds to protect against unexpected incidents.

SUNBEAMsystem’s SMART LITHIUM series boasts certified resistance to penetration, crushing, fire, repeated vibrations, shock impact, short-circuiting, and overcharging, positioning it as one of the safest battery options available. Our layered safety approach has also secured the series a distinguished air transport certification under UN 38.3 legislation, reinforcing its top-tier safety qualifications.
