Purchased a couple Dimension Engineering CellShields. They are low voltage cut-off devices. It has a dial to set the cut-off voltage between 2.5 and 3.5 volts. I set it at 3.5. my fellow members of this forum recommend a 3.5 low voltage cut-off so that the resting voltage is around 3.7 volts. At 3.5 I cannot run the model as the low voltage cut-off kicks in almost immediately. So I called the manufacturer and asked them why it was kicking in so quick. They told me that they recommend a setting around 3.0 volts. I think I would destroy my batteries with that setting. why is there such a difference of opinion. I run revolectrix 420 silver graphenes 70c. 5,000 mah. 5s and 3s lipos. Any input is appreciated here. Thanks. By the way, these units are meant for electric aircraft. Is this why the recommended voltage cut-off is much lower ?
