How It Works
The heart of the system is a smart battery combiner that handles connecting / disconnecting the batteries automatically.
When the engine starts, it allows the engine to charge the cranking battery first, then links the batteries together in parallel so they can both be charged by the alternator.
Once it sees the voltage drop below ~12.7v for a minute, it will separate the batteries. Your accessories connected to the bus bars continue to run from the second battery and won't drain your cranking battery.

Smart Combiner Specs
The heavy duty Smart Battery Combiner device is rated to handle 300 amps continuously flowing through it. It can handle higher amperage loads for shorter durations - 500 amps for 5 minutes, and up to 2,000 amps for 5 seconds. The combiner requires a minimum of 8 volts to operate. It does not consume any power to keep the batteries connected together, and it does not generate any heat.
