Recently, sometime in the last 4 months, my max battery power @90% @5 minutes from max battery ready(i.e. not fully warm but close) has dropped from 458KW (1535 amps * 298 volts) to 336KW (1535 amps * 284 volts) (+- a few KW). It seems like it must be battery degradation since the current remains at 1535 amps but the voltage has dropped at the same charge level at the same temperature. Prior to the upgrade, max power under the same conditions was 414KW, so this represents about half of the Ludicrous upgrade lost. Just curious what other P85D owners Insane or Ludicrous are seeing under the same conditions?
