    Electrical help please - lost and confused - calculating battery needs for uses

    Based on my experience, Tiger Adventure Vehicles went to using Blue Sea ACR's with a single run of 1/0 AWG. The results were functionally the same and the cost was lower. You can use the voltage drop calculator and compare a single 1/0 AWG with 2x1/0 (or 4/0AWG) and see for yourself. The rate...

    Sand ladders for a 15 ton overland truck???

    Don't know about weight ratings, but they used to have videos of tractor trailers and military trucks that weigh more than my truck.

    Electrical help please - lost and confused - calculating battery needs for uses

    "Multi-Stage" charging is partly, but not entirely a marketing ploy. Much of the process is controlled by the natural reactions of the lead acid battery to its charge source. -- To charge a battery, the charging source - alternator, shore charger, solar controller, or simply another battery...

    Electrical help please - lost and confused - calculating battery needs for uses

    Golf Cart = Deep cycle, aka forklift or traction. Big plates. There is no magic to 6v batteries. You are going to build a 12v bank, so mix and match as required. Because of marketing (e.g. golf carts) there are a lot of high amp 6v batteries. With lead acid the weights are so high that you...

    Electrical help please - lost and confused - calculating battery needs for uses

    You really need to do a bit of reading on your own, rather than simply shotgunning questions to the Internet. You are going to have some serious $$$ tied up in this. This may help: https://cookfb.files.wordpress.com/2016/09/battery-charge-slides.pdf To one of your specific questions, you want...

    Redarc vs Ctek

    You are mixing and matching a bit. Reading this may help: https://cookfb.files.wordpress.com/2016/09/dual-battery-slides-2016.pdf -- The Superpower appears to be an intelligent relay. If dwh is correct, and he usually is, the wire you are worrying about is simply to allow you to force close the...

    Redarc vs Ctek

    Please identify the misinformation. For the record: -- I use and like REDARC products; in fact, I have two in my truck. (Mostly because of 24v to 12v conversion.) I am a total RECARC phanboi and they offer GREAT support! -- The BIG issue with REDARC DC-DC chargers is the low output. (Also an...

    Greetings! Got a Mog project, need some advice from experienced folks

    What would I do? I would do what I did. Drive to La Junta, CO and knock on the door of Terry Lee Enterprises. (Warm up the vinyl.) The website is terrible but the service and knowledge of all things Mog is worth every penny. http://www.terryleeenterprises.com

    Redarc vs Ctek

    No crane, four 300 Ah 6v batteries. ;) In my case, 250A of alternators and typically 135Ah of discharge. This meant that the initial charge rate was about 100A, dropping by about 1/2 about every 1/2 hour. Typically spent at lot of time between 25 and 50A max charge. Also, 500w of solar, which...

    Redarc vs Ctek

    Depends on the vehicle, or more properly, the voltage of the charging system. I used an intelligent relay on a 2013 Chevrolet and it had no problem charging a 600 Ah AGM battery. The limitation was driving time, not voltage. Can't comment on Nissan, but many vehicles top out at 13.9v, in which...

    Redarc vs Ctek

    You are most welcome to your own opinions; my numbers are based on years of real world living with a 600 Ah AGM battery bank. This actually covers two different vehicles, two different charging setups but the same size battery banks and basically the same appliances. With an AGM battery down to...

    Redarc vs Ctek

    Not really an issue; they won't. This assumes of course, that each charger is set correctly. The CTEK, with the SmartPass will give you a higher charge rate, but, depending on your voltages, you might be better off with a relay (I like the Blue Sea ACR) and properly sized wires. This plus you...

    Redarc vs Ctek

    I use the built in solar controller, but it should be noted that the total output of the charger does not change, all that changes is the source of the charge. That is, the REDARC favors solar over alternator. If you want to increase the total current available, then you will need a separate...

    Redarc vs Ctek

    First question, do you really need a DC-DC charger? The odds are good that your Power Wagon already charges at the correct voltage. Check that first. You may be able to get away with a simple switch, key controlled relay, or intelligent relay. If you really NEED a DC-DC charger: -- Sterling...

    Dual battery opinions

    Sorry, was responding to your three numbered points. Can't help you with the Genesis. Don't have a Tundra but I do know that some Toyotas only get up to 13.9v, which is a bit low. Best wishes!

    Dual battery opinions

    This subject has been beaten into the ground and I have three potentially useful documents on my website, that said: -- Dual batteries to save yourself from killing the camper battery is a bad idea. Size your camper battery for your needs, so that you cannot kill it. -- Charging a lead acid...

    Most, most impressive. As a total composting toilet phanboi, l love your doorway installation, especially with the shower integration. Much better than anything I have ever dreamed up!
