I'd like to use an MCP73831 to charge my lipoly battery. In section 6.2 I see they recommend short wires to the battery.
I bought my battery with wires, 20 gauge and approximately 30cm long. The maximum charge current will be 500mA. I know that there will be a voltage drop over the wire and I therefore will lose power. This power loss will be very small: \$0.60\cdot0.03331\cdot0.5^2=0.0049965 W\$ (length, resistance / meter, current). So I don't see how this is a good reason to keep the traces as short as possible.
So besides reducing power loss, is there any reason to keep the traces as short as possible?
