WebDec 23, 2024 · LFP batteries are fully charged at 0.05C @3.65V/cell. That's a 5% tail current. In order to register a sync, the current needs to fall BELOW the tail current while at charged voltage. OP is charging to 3.60V/cell, so that's close enough. If you're charging LFP to a lower voltage, you will need a lower tail current. 2% would not be unreasonable. WebAug 22, 2024 · The accuracy can be maximized by choosing a large shunt resistor. However, in a high-current precision application, the power dissipated by the current sense resistor can limit the maximum resistor value that can be used. In this case, we can choose the maximum value of R shunt based on its maximum allowable power dissipation.

WebSep 5, 2024 · Current sensing (shunt) resistors are subject to power loss calculated by P = I2R (derived from Ohm’s Law). Therefore, to keep the dissipated heat low in order to avoid self-heating and its effect of the resistance itself, the device manufacturers offer the range of available resistance values down to the milli- and microohm region.
