This is the second version of Scotty DC DC called Scotty AI DC DC

Five Reasons Why to buy Scotty AI DC DC for Lithium Battery Charging from an Alternator.

Name: Safiery SCOTTY AI 3kW 12-48V CANbus, Bi-directional DC to DC
SKU: CPC124815080-IP66-12V
Availability: InStock

Scotty AI DC DC uses the internal regulator of an alternator. Factory Supplied.
Scotty AI DC DC does NOT modify or add to the alternator in any way.
Scotty AI DC DC has an accurate temperature sensor that is placed on the alternator housing.
When Scotty AI is running, the machine learning logs the alternator temperature operating range.
AI monitors rate of change of temperature with current, time and voltage to identify out of range conditions.
When out of range occurs, Scotty AI sets the mode back a level: Hard to Medium, Medium to Soft and Soft to Off.

Scotty AI DC DC does not need to know alternator or engine speed.
The patented SCOTTY AI program maps the voltage and current with current rate of change to determine the optimal operating curve.
The result is plug-n-play that your son or daughter can auto-tune from the Smartphone App.

When an alternator gets hot, its efficiency and output level changes. External Alternator regulators find this hard to control.
Scotty AI DC DC auto-tunes to the changing load and changing efficiency of the alternator.

When the solar yield is poor and you need maximum DC DC power at Idle, just dial up “HARD” on the optional Touch Display or the Smartphone App.
Your alternator is protected by AI. Should the temperature goes out of bounds then the setting will be automatically adjust back to medium.
You just sit back and relax.

Scotty AI runs on the 250 baud VE.CAN port together with compatible lithium batteries.
It charges to the Charge Current Limit Set by the BMS
If no BMS, then it charges to Max Voltage set on Smartphone App and stops charge either when voltage is reached or the “Stop Charge” wire input is activated or deactivated.

Scotty AI will switch to supply 12V or 24V loads in 25ms.
If there is a big winch or other 12V or 24V load, it will also switch even when the alternator is running. Simply turn “off” on the Smartphone App or Optional Touch Display. The full additional power is delivered to the starter battery in addition to the alternator power.

Scotty Meteor AI will Plugs to front of Meteor train
The CAN connection, Voltage and power bus connection are all internal.
The Positive Plug that attaches to front of Scotty AI meteor has two Megafuses. One at 12V and the other at the Meteor Battery Power Supply.
