// Default parameters. The selected row (as indicted by the DIP switches) is copied from the FLASH into the working "chargeParms" variable
// during Startup(). Also, the EEPROM is checked to see if there is a replacement entry for the default values and if so, those are
// copied.
//
// CAUTION: ALL ENTRIES IN THIS TABLE ASSUMES A NOMINAL 12V / 500Ah - SMALL SIZED BATTERY SYSTEM.
// THEY WILL BE AUTOMATICALLY ADJUSTED FOR HIGHER VOLTAGE / CAPACITY BATTERIES VIA THE AUTO-SENSING CAPABILITY.
// When populating this table, if you have a higher voltage battery (ala 48v), then make sure to scale
// these appropriately back to a '12v' value (ala, divide volts / 4, mult Amps by 4)
//
// The CPEs below have been defined assuming the Amp shunt is INSTALLED AT THE BATTERY vs. at the Alternator. If the regulator is configured
// with the Amp shunt on the Alternator, exit_amp values need to be adjusted to accommodate house loads. A suggestion is to add 5A to each
// 'threshold' value, with assumption that ship running loads will be around 5A for a small boat.
// These will scale with the Battery Size scaling switches, so that a larger boat with say a 1500AH battery, that 5A will turn into 15A.

// Side note: The Arduino programming environment will place the above populated table into EPROM during compile time.
// Upon power on, the Startup code will copy the selected CPE entry (table row) into RAM for use.
//
// These values are normalized for a 500Ah/12v battery, and when used are adjusted as follows:
// - Volts: Increased (multiplied) by battery voltage scaling factor - "systemVoltMult"
// As determined by auto-sensing the battery voltage at startup (or forced override via ASCII command).
// e.g.: at 48v system would multiply all voltages above by 4
//
// - Amps: Increased (multiplied) by battery capacity scaling factor - "systemAmpMult".
// As selected by the System Size DIP switches (or forced override via ASCII command).
// e.g: A 1000 Ah battery was selected -- a capacity of 2x -- and Amp values will be increased by 2x before being used.
//
//
//
// - Temps: BAT_TEMP_1C_COMP is increased (multiplied) by battery scaling factor.
// As determined by auto-sensing the battery voltage via the RAW Atmel A/D port.
// e.g.: at 48v system would multiply BAT_TEMP_1C_COMP above by 4
//
// Entries that are NOT modified are:
// - Temp Limits: MIN_TEMP_COMP_LIMIT, BAT_MIN_CHARGE_TEMP and BAT_MAX_CHARGE_TEMP are not scaled.
//
// - Time values: No time value is modified
// Note that the temp limits (ala min and Max temps) are NOT changed.
