EGO ARC Lithium MAX: New battery technology for more power and faster charging
With its new generation of ARC Lithium MAX batteries, EGO is introducing innovative tabless cell technology. This enables higher power output, shorter charging times and a longer service life. Two new 56V batteries, the BA1680X and BA3360X, are scheduled to launch in early 2027, expanding the existing EGO battery system. But how does this new technology work, and what benefits does it offer in everyday use?
What is the new EGO ARC Lithium MAX technology?
High-performance batteries are at the heart of modern cordless outdoor power equipment. Whether mowing lawns, trimming hedges or blowing leaves, the key factors are not just battery capacity and runtime, but also available power, charging speed and service life.
With its new ARC Lithium MAX technology, EGO is taking its proven 56V battery system to the next level. At the centre of this development is a new generation of lithium-ion cells featuring tabless cell technology.
This technology enables higher electrical power output while reducing heat generation inside the battery cells. The result is powerful, compact batteries that can be charged more quickly and are designed to deliver a longer service life.
Tabless cell technology: How does it work?
To understand the benefits of the new EGO batteries, it helps to take a closer look inside a battery cell.
Conventional cylindrical lithium-ion cells have individual electrical connection points known as tabs. These are used to transfer electrical current into and out of the cell. As a result, the current sometimes has to travel relatively long distances, increasing electrical resistance and generating more heat, particularly under heavy loads.
This is exactly where the new tabless technology makes a difference.
Instead of individual connection points, tabless cells feature numerous parallel contact points along the edges of the electrodes. This allows electrical current to flow across a much larger contact area.
The electrical paths inside the cell become shorter, internal resistance decreases and the heat generated is distributed more evenly.
This offers three key advantages:
More power: lower internal resistance allows the cells to deliver higher currents, which is particularly beneficial for demanding applications.
Faster charging: reduced heat generation enables higher charging currents and therefore shorter charging times.
Longer service life: lower thermal stress can reduce cell ageing and help extend battery life.
Tabless technology therefore does more than improve individual performance characteristics. It provides the foundation for a more efficient generation of batteries.
More power, less charging time: Benefits in everyday use
The technical improvements of the new ARC Lithium MAX batteries are particularly noticeable during demanding tasks and extended periods of operation.
Higher power output for demanding applications
Power-intensive tasks, such as mowing thick grass or operating high-performance cordless leaf blowers, require the battery to deliver large amounts of energy, either for short periods or continuously.
Thanks to tabless cell technology, the new EGO batteries can deliver higher currents. This increases available power reserves and supports consistent power delivery, even under heavy loads.
Faster charging and less downtime
Charging time is a particularly important factor for professional users. The faster a battery is ready for use again, the less time is lost between tasks.
The new EGO BA1680X 3.0 Ah battery can be recharged in just 20 minutes using a suitable fast charger. According to the technical specifications, the BA3360X 6.0 Ah battery takes approximately 35 minutes to charge with the CH7000E-T.
These short charging times make it easier to plan longer working days and allow users to alternate more efficiently between working and charging.
Less heat for a longer service life
High temperatures are among the factors that can accelerate the ageing of lithium-ion batteries.
Thanks to optimised current flow, tabless cells generate less heat. At the same time, the heat is distributed more evenly throughout the cell.
This reduces thermal stress and creates favourable conditions for a longer battery life, particularly with regular and intensive use.
New EGO ARC Lithium MAX batteries arriving in early 2027
With the BA1680X and BA3360X, EGO will expand its ARC Lithium MAX range with two new battery models in early 2027. They will complement the already available BA4480X 8.0 Ah battery, providing additional options for different power requirements.
EGO BA1680X – compact and powerful
The new BA1680X has a capacity of 3.0 Ah, equivalent to 168 Wh. Despite its compact design, it delivers up to twice the power output of the previous BA1400T.
Weighing approximately 1.3 kg, it is particularly suitable for applications where a compact design and low battery weight are important.
EGO BA3360X – more energy for longer working periods
The BA3360X offers a capacity of 6.0 Ah, equivalent to 336 Wh. Compared with the previous BA3360T, it delivers 33% higher power output while featuring a more compact design and lower weight.
At approximately 2.2 kg, it combines high energy capacity with improved performance.

Frequently Asked Questions About the New EGO Batteries for 2027
What is a tabless battery?
In a tabless cell, electrical current does not flow through just a few individual contact points. Numerous connection points distributed throughout the cell shorten the electrical path, reduce internal resistance and minimise heat generation.
Which new EGO batteries are coming in 2027?
The ARC Lithium MAX range will be expanded with two new models: the BA1680X with 3.0 Ah and 168 Wh and the BA3360X with 6.0 Ah and 336 Wh.
What are the benefits of EGO's tabless technology?
This technology enables higher current output while reducing heat generation and distributing heat more evenly. This provides advantages in terms of power output, charging speed and potential battery lifespan.
How quickly can the new EGO batteries be charged?
With suitable fast-charging systems, the BA1680X has a stated charging time of 20 minutes. For the BA3360X, the charging time overview specifies 35 minutes with the PGX2500 or CH7000E-T.
When will the new EGO batteries be available?
The new BA1680X and BA3360X batteries are scheduled to launch in early 2027.
