Description
Discover the 66160K 2.3V - 45Ah LTO A-Grade from Yinlong, an excellent quality lithium LTO round cell. Popular for its efficiency and economy, this cell offers outstanding performance, which is particularly noticeable in large quantities. The Yinlong 66160K 45Ah cell is rounded off by its versatility of use, as in combination with at least five other cells it achieves a nominal voltage of 13.8V with 45Ah capacity, particularly in the automotive sector.

Notes on LTO cells
- The optimum operating range of YINLONG LTO cells is between 2.0V and 2.5V.
- When charging the cells above 2.5V, the voltage rises more strongly, above 2.6V very strongly. The situation is similar when discharging below 2.0V!
- It is therefore also very important to use a good active balancer for LTO cells that are connected in series.
- When working with very high currents (charging or discharging), it may be necessary to further restrict the operating range in order to avoid large voltage increases or voltage drops.
Difference between LTO - LiFePO4 lithium batteries
Lithium titanate cells (LTO)
- + extremely long service life
- + 10x longer cycle life than LiFePO4 cells
- + extremely safe
- + Very high charging and discharging currents possible (5C-10C)
- + weniger temperaturempfindlich, kann auch bei <0°C geladen werden
- + now affordable, cells have become cheaper
- + Very long service life (>25 years)
- - LTO is more expensive than LiFePO4
- - higher weight or less capacity
- - lower cell voltage (2.3V), therefore more cells required for the same battery voltage
Lithium iron phosphate cells (LiFePO4)
- + favorable price
- + Large variety of capacities and sizes
- + higher capacity
- + higher cell voltage (3.2V), fewer cells required
- - shorter service life
- - not quite as safe as LTO
- - max. charging and discharging currents are significantly lower (2C-3C)
