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.

Glad to see a more DIY solution and love the rear power panel. Would love to hear about what influenced the various decisions on each of the components (25amp vs 40 amp redarc, AGM battery choice, etc). Thank you again for another great production.

@WanderlostOverland 5 жыл бұрын

Thanks for watching!"25amp vs 40 amp redarc"- We were up in the air on this too. That's partially why we got help from OPS. They said the 40amp wouldn't be necessary for our application. "AGM battery choice"- Mostly cost. We could either buy a $400 or $200 battery. Both would perform and last about the same. $200 won out. :)

Nice, def a quality job. If you still have your Toyota and your Redarc supports lithium you might want to upgrade the batt. AGM only allows 50% drain where lithium with the same rating and size will let you drain 80% or more if done only occasionally. Lithium has a much longer usable life as well. I can recommend the Renogy batteries. I've been using 2 non smart non bluetooth ones for over 5 years with no issues. I paid over $1000 each, now they're running for only $429 each. Non smart does not mean they don't have self contained battery management systems n temp probes.

@ricki11cook 5 жыл бұрын

Just a suggestion, as I recently did an almost identical setup, but with a lithium, BCDC1250D & 0AWG cables for the current draw. You should physically move your Victron current shunt up to your AUX battery, terminate all negatives to the load side & just the AUX batt neg to the “Battery Only” side of the shunt. Then it will actively monitor the charge going into the battery from the Redarc as well as the draw from it. Then you might actually see some positive current figures instead of constant -3.5A for e.g. It will also give you a true indication of battery terminal voltage & not post the loss of the 4AWG cable run to the rear of your vehicle. The shunt also has an “Aux” input, connect that to your starter battery & you can monitor the terminal voltage of that as well. Enables you to set audible alarms if it drops below a threshold. Victron also supplies a long (10m from memory) comms cable in the kit to go between the shunt & BMV-712.

@WanderlostOverland 5 жыл бұрын

After seeing your comment we reached out to Victron and it turns out you are correct. We do have it wired incorrectly. The way we show in the video is how the company who designed our system told us to wire the shunt. Thank you for pointing out the mistake in a kindly, respectful manner.

cool video, but I'll mention that redarc doesn't suggest using circuit breakers in the charging line for their BCDC units as they generate a lot of heat. The heat can lead them to popping open when there isn't a fault in the system. Alternativly, they suggest using a MIDI fuse which is very low resistance.

Awesome video, i got a few points. 1) the 5th gen 4runner has a temperature compensated alternator, as such I do not think the blue ignition wire was necessary. Why did you choose to hook it up? 2) In their manual, REDARC does not like breaker and recommend MIDI type fuse, personally, I think a good breaker like the bluesea is not an issue. It will interesting to see how it performs. 3) Did you duse the brown wire? Albeit short run but expect to see 35amps at times. 4) You grounded both batteries together, if the charger is grounded to neg pole of accessory battery, isn't it sufficient? Why adding a ground to the body? 5) Why did you choose AWG 4 wire? Most amps you will see in the engine bay is 35 amps, even with both batteries separated this way, AWG 8 could be enought. However, bigger does not hurt. Sorry for so many questions but hope it could help to clarify. Thanks again for putting time and effort doing this. Cheers

@davidroossien1154 2 жыл бұрын

On the wire size from the starter battery to the second battery, it seems to me that the DC-DC charger provides starter battery isolation from load spikes on the second battery. Since there won't be as much inrush current into the DC-DC charger from the starter battery a smaller wire gauge like 8 AWG should be acceptable. Given that the DC-DC converter is rated for 25 amps, and the length is about 9 feet, wire guides recommend 8 AWG. 48 amps is the max current on an 8 AWG wire, which matches the breaker size. 8 seems acceptable and 6 AWG seems like a conservative choice.

@davidroossien1154 2 жыл бұрын

Indeed, 8 AWG is recommended in the manual for the BCDC1225D with 3-16 foot cable length.
