Notes on LTO Cells:

• The optimal operating range of YINLONG LTO cells is between 2.0V and 2.5V.
• When cells are charged above 2.5V, the voltage increases more steeply, above 2.6V very steeply.
• The situation is similar when discharging below 2.0V!
• It is very important to use a good active balancer for LTO cells connected in series.
• When working with very high currents (charging or discharging), it may be necessary to further limit the operating range to avoid large voltage increases or decreases.
