Notes on LTO Cells

  • The optimal operating range of the YINLONG LTO cells is between 2.0V and 2.5V.
  • When charging the cells above 2.5V, the voltage increases more sharply, and above 2.6V it increases very sharply. The same applies when discharging below 2.0V!
  • Therefore, the use of a good active balancer for LTO cells that are connected in series is also very important.
  • "If very large currents (charging or discharging) are used, it may be necessary to further restrict the working area to avoid strong voltage spikes or drops."

A high-quality active balancer is recommended for cells connected in series. Optimal voltage levels ensure not only longevity but also the best possible performance and efficiency of the cells in various applications.
An active balancer is essential for the LTO cells from GS Audio when they are connected in series. The cells have a specific voltage of 2.0V to 2.5V, with voltage deviations outside this range potentially affecting their lifespan. The balancer prevents unequal charge states and stabilizes the cells, leading to a longer lifespan. Especially at high charge and discharge currents, unexpected voltage fluctuations can occur, which are efficiently balanced by the balancer.
Yes, the use of the LTO cells from GS Audio in low-temperature environments is easily possible due to their temperature stability. The operating temperature of -55°C to 65°C allows the cells to be used efficiently in cold environments as well as under warmer conditions. This makes them particularly suitable for outdoor applications or in geographical regions with extreme temperature differences, which is often not the case with other cell types.
LTO cells, like those from GS Audio, differ significantly from LiFePO4 cells in several respects. They offer an extremely long lifespan and up to 10 times higher cycle life. LTO is also safer and supports high charge and discharge currents of 5C-10C. Furthermore, they are less temperature-sensitive and have a higher calendar life. In contrast, LiFePO4 cells are equipped with a higher cell voltage of 3.2V and are typically cheaper with a wider variety of available sizes.
The 6 cells LTO from GS Audio are particularly suitable for solar storage, as they offer extreme longevity and safety. They also eliminate the need for capacitors in car hi-fi systems, as they can store high currents. In campers and caravans, they prove advantageous due to their insensitivity to temperature. As starter batteries, the high current flow allows for quick starting. On boats or in UPS systems, they also provide excellent service. Thus, they are extremely versatile, depending on specific energy requirements and environmental conditions.

Dimensions and weight of the GS Audio LTO single cells

These LTO single-cell drives from GS Audio have precise dimensions of 160 mm high and 66 mm wide and deep. Weighing approximately 1.25 to 1.3 kg, they are perfectly designed for space requirements and portability. This sophisticated design balance minimizes the impact on the overall weight of the vehicle's sound system. Their compact size allows for flexible integration into a wide variety of applications, from mobile sound projects to stationary power banks in car hi-fi systems.

Performance parameters of the 40Ah and 45Ah cells

A striking feature of the GS Audio cells is the capacity difference of 40Ah and 45Ah, which allows for enormous flexibility in use. The maximum discharge current of 400A for 40Ah and 450A for 45Ah demonstrates that these cells retain robust functionality even in high-performance applications. Higher capacity guarantees longer runtimes, while the high peak current can smoothly handle rapid load changes. A higher capacity than stated here would further extend the operating time, but at the expense of cell weight and size.

Recommended charging and discharging currents for maximum longevity

The optimal charge and discharge currents are specified as 40A for 40Ah cells and 45A for 45Ah cells. These values ​​guarantee an optimal balance between battery performance and service life. Regularly working with maximum currents of 400A or 450A, you'll utilize the cells' full potential, albeit with reduced cycling advantage. Increasing these optimal currents would result in high performance in the short term, but would accelerate cell aging.

Voltage ranges and their effects on the cells

The voltage range of 1.8V to 2.65V (manufacturer's specification: 2.8V) defines the operating range of these single cells. Avoiding the maximum voltage values ​​preserves the battery's longevity, ensuring a capacity difference of less than 0.5 Ah compared to the manufacturer's specification. An increased cell voltage leads to a direct voltage increase, which would compromise the cell's electrical integrity in the long term. Note that adhering to the optimal voltage ranges is recommended, even during extreme temperature fluctuations.

Temperature suitability and adaptation to environmental conditions

A distinctive feature and key advantage of GS Audio LTO cells is their temperature performance. They operate reliably between temperatures of -55°C and 65°C. This results in extreme flexibility, making them ideal for outdoor use or the varying climatic conditions found in vehicles. This technical design allows for consistent and reliable power delivery even under unusual temperature conditions.

Connection and integration into systems

The redesigned contact surfaces of the GS Audio cells minimize contact resistance, resulting in more efficient energy transfer. Combined with an active balancer BMS system, this ensures improved cell balance, especially in series systems, thus increasing overall energy efficiency and consistent power output. This technical enhancement enables the trouble-free use of high charge and discharge currents, giving you flexibility in the design of your energy system.

Comparison of LTO vs. LiFePO4 battery technology

Lithium titanate oxide cells offer significant advantages over lithium iron phosphate cells in terms of cycle life, safety, and capacity. With up to 10 times longer cycle life, you can rely on the cells' long-term performance. Their ability to handle very high charge and discharge currents makes them an excellent choice for applications requiring dynamic energy output. Increasing the cell voltage would require fewer cells, but this would come at the expense of the exceptional cycle life of LTO cells.

Expansion options for system voltage configurations

These LTO cells are ideal for building systems with different voltage requirements, ranging from 12V systems with 6 cells to 24V systems with 11 cells to 48V systems with 22 cells. This flexibility is especially useful if you want to integrate customized energy solutions into your vehicle.
