We show you what we consider the best dual battery system for powering an automotive fridge and accessories. And, we show you in detail how to install it! We also show you how we made and wired our outlet/gauge panel.
While researching second battery systems we learned about Redarc dc-dc chargers. It didn’t take long for us to decide a dc to dc charger was the direction we needed to go in. They make for a super efficient power source.

The majority of the parts and components we use for the install were obtained from Overland Power Solutions.
Below are links to where we got everything else.
This video will explain in greater detail why you should choose a dc-dc charger;

A new episode of my Dr Vstrom, medical video series on how to maintain (Check, Connect & Smart Charge) your motorcycle Battery. This video:
-Informs on almost everything you need to know about batteries including how to keep them alive during the winter or long periods of motorcycle immobilization.
-Demonstrates how to remove your battery, check its state & how to reinstall it along with a modern 2-pin, ring terminal harness that allows fast, fuss-free connections of other devices with your battery.
-Connects to another video in my channel such as the “How to Maintain & Test your motorcycle Battery & Charging System | DL650 Vstrom”:
1. Battery Terminal Cleaning,
2. A Static Battery Voltage Test,
3. A Starting Load Test &
4. A Charging System Test or (Regulated Voltage Test)
This tutorial demonstrates on a 3rd Gen DL650 Vstrom L7 model but the steps are applicable to the entire Vstrom family as well as all other motorcycles & batteries out there.
This is a quick video that shows how to install an onboard battery charger for your bass boat with a 24v trolling motor. The only thing I skipped was the template installation and drilling because I bought the same one that was installed previously. Lasted a long time and did a great job!!!

Step by step Battery Isolator instal (12V 140 Amp Dual Battery Isolator by KeyLine Chargers – Voltage Sensitive Relay (VSR) Pro Dual Battery Kit)l. This isolator kit connects the starter battery in your vehicle to a secondary “house” battery. The isolator tests for a proper charge level from the starter battery prior to charging the 2nd battery. If the starter battery falls below the starting threshold the isolator will shut off so that the starting battery still retains enough starting power, and does not get drained.
This system also allows for powering the auxiliary battery with a solar panel with a charge controller. This facilitates long-term boondocking by providing power for your electronics.

The Schumacher SE series SE-82-6 is a battery charger with 12v/2a, 12v/6a and 6v/6a charge settings. The only way to turn on/off the charger is by removing the wall outlet connection. This is unsafe due to constant power being supplied to the battery clamps even when not connected to the battery. So a convenient and safe 125v 15a switch was put in line with the positive connector to safely, quickly and conveniently supply power to charge batteries while preserving the integrating of the wall outlet cable.
