Description
Discover the 66160H 13.8V - 40Ah LTO Set 2, presented by Yinlong. This set brings the classic 40AH LTO 66160H round cell, which is an extremely popular version, directly to your home. Rely on good quality and work smarter, because this lithium titanium oxide battery set provides you with up to 6000 watts RMS - enough for high performance requirements. In addition, these batteries can be produced in large quantities and cost less than comparable models on the market. Their voltage, size and capacity make them a robust and reliable energy partner.
Features
- 1 set of 6 LTO cells is sufficient for an amplifier output of approx. 6000 watts RMS
- Open-circuit voltage: 13.8V-14-4V
- At least 6 cells are required for a 12V system. 11 cells in a 24V system.
The self-assembly kit contains everything you need
- 6x original Yinlong LTO 66160H 40Ah cellsÂ
- 5x aluminum connectors (must be filed or drilled out slightly if used with the black cell holders)

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
-
the cells do not burn! even with cut tests, drop tests and co, no fire will occur, as is known from other lithium batteries!
- + 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)
