LiPo Internal Resistance
To calculate voltage drop of this pack, we then would use good old Ohm''s law (V = I x R). A real world current draw number for a larger electric powered RC vehicle might be around 50 Amps, so plugging that into our formula would be V = 50A x 0.016 Ω giving us a voltage drop across the battery of 0.8 V.
