Notes on LTO cells
- Der optimale Arbeitsbereich der LTO Zellen ist im Bereich von 2,0V bis 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)
Connection of the active balancer BMS
Possible applications
- Solar storage tank (extremely durable and safe)
- Car Hi-Fi (capacitors superfluous)
- Camper and caravan (temperature insensitive)
- Starter battery (very high currents possible)
- Boat battery
- UPS
- 12V system - 6 cells
- 24V system - 11 cells
- 48V system - 22 cells
