well the steps that i have in the meter is controlled by how LiPo & Li-ion battery's discharge/capacity graph is, not saying it is impossible to make the steps you talk about, but making the steps like they are now because they fit as closely as possible to the REAL graph took some hours to make. The high load is how a battery reacts, my EV moped uses 110A at 22V (under acceleration) and the voltage drops to 19.5V from 22V.
