Genesis Offroad Gen 3 Dual Battery System (200 Amp Isolator) | 182-TTUDBKG3 | 2007-2021 Toyota Tundra

Our Gen 3 dual battery systems use a smart combiner to charge both batteries in parallel from your alternator. No wiring diagram to figure out, no special tools required!

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.

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.

Features:

• Bus Bars:
  • Adding electrical accessories to your vehicle has never been easier! Devices connected to the bus bars run from the Aux battery and will not drain your cranking battery.
  • 3 sizes of studs for connecting heavy wires like your winch, stereo amps, fuse boxes, etc. Connect smaller ring terminals to the small screws.
• Boost Switch:
  • Auto - Connects the batteries automatically based on their voltage level
  • On - Manually connects the batteries together just like jumper cables to help start the engine
  • Off - Manually separates the batteries
