WebLithium-ion batteries have a narrow Voltage window, for both charging and discharging. Going outside that window very quickly results in permanent damage, and on the high end a possible RUD Event (NASA-talk, as mentioned before). For LiFePO4 that window is about 8.0V (2.0V per cell) to 16.8 Volt (4.2V per cell). Webimportant design consideration: a "flatter" discharge curve means less voltage variation that the design must tolerate. When peak charged, the actual cell voltage will be higher …

WebOn the flip side of a partial charge is a partial discharge. Rather than a full cycle, this is known as a partial cycle. It has the benefit of reducing stress on your battery and increasing cycle life. So instead of discharging all the way down to 2.8V or however your battery is rated, you might only discharge to 3.2V.
