    DC/DC charger + Solar musings

    What type of house battery do you have? If it's SLA then you can just connect straight to the starting battery with no controller. There will be some losses in the wire but it will work if you drive long enough. It's not the best way of doing it but it works. If it's a different type than...

    Simple Lead Acid to Lithium Iron Phosphate

    I recently switched over to LiFeP04 batteries and so far I am very happy with them. Twice the usable capacity, half the weight, charges much faster, and 10x the lifespan of SLA. The initial cost was hard for me to overcome at first, but when I did the cost per Ah calculations over it's...

    CJ-6 "Rat Bastard"

    Remove the distributor and look down the hole for the oil pump groove. You need to align the bottom of the distributor shaft with the groove. As you noticed, the dizzy will rotate wile engaging the gear, so just offset to account for it when you insert may need to use a long flat head...

    LiFeP04 charge controller recommendations

    To update this thread, I ended up getting a Victron MPPT controller, I think it was the 100/20 linked above. I also picked up a Renogy 30A DCDC charger. However, I'm having second thoughts and might switch over to the Renogy DCC30S or Kisae SCD1230 which are integrated charger/controllers...

    LiFeP04 charge controller recommendations

    I don’t remember where I read it, probably a solar forum or RV forum, but an MPPT controller could potentially short the input side of the controller. On a solar panel it wouldn’t be a big deal, but connected to battery or alternator that’s probably not a good idea. Not sure how true it is...

    LiFeP04 charge controller recommendations

    I think I’ve had a change of heart and will probably go with a separate solar controller and DC-DC charger as suggested. Been doing a little more reading and it looks like using an MPPT controller as a dc charger might not be a great idea. I found a Renogy 30A combination dc charger and mppt...

    LiFeP04 charge controller recommendations

    That's so simple it's genius. Its exactly the type of answer I was looking for. I will probably do the same thing. I was wondering whether the charge controller would still work with the 13.8V input of the alternator, but with a converter I don't have to worry about it. I want to limit...

    LiFeP04 charge controller recommendations

    Need recommendations for a new charge controller/dc battery charger. Right now my current setup is a deep cycle battery charging from the alternator through a relay when the engine is on, then switches over to 100W solar using a Renogy 10A charge controller. This has been working fine for a...

    How to pump creek water 60M+ to hot water system?

    Have you tested your 12V pump? I doubt you will get anywhere near those specs, at least not all at once. It might be able to pump 30M, 1.8M, 55psi, or 6L/m, but it'll only meet one of those specs at one time. I have a 1/2 hp (400watt) sump pump that rated for 2000gph and 16ft of lift, but...

    Dual battery setup for a fridge

    These calculations would be at worse case scenario, like if you were to load the fridge with warm bottles of water and tried to freeze them on battery power. Then the fridge would be running on 100% duty cycle at max current until everything has come down to the set temp. In normal use, I've...

    Sad End to This Cautionary Tale, As Folks Start to Head Back Out Into the Wilds, Pls Be Careful

    Considering they had 2 flats going in, what were there chances of making it back out without getting more flats? I think people overestimate the ability to drive on flat tires. This is what driving on one flat tire looks like after about a mile, driving on the shoulder of a highway, and I...

    Sad End to This Cautionary Tale, As Folks Start to Head Back Out Into the Wilds, Pls Be Careful

    I would say it's a pretty similar comparison. The area that the Germans were found on in probably gets a similar amount of traffic as the area this couple was in, if not more. I have seen a lot more trip reports in the Warm Springs canyon area due to fact it has a cabins and some mines, and is...

    Sad End to This Cautionary Tale, As Folks Start to Head Back Out Into the Wilds, Pls Be Careful

    Generally, I would agree that's good advice, but you have to be careful in applying it to all situations. Especially in a place like Death Valley. Just because you're on a road in DV doesn't mean you're going run across people. Even during peak season when there are thousands of people...

    Sad End to This Cautionary Tale, As Folks Start to Head Back Out Into the Wilds, Pls Be Careful

    Agree 100%. A topo map can give you an overall sense of the terrain, but even the best map will not tell you whether or not an area is passable or impassable. There are plenty of places that look worse on a map, but are easily hikeable, and other areas where a map can't convey the difficulty...

    Is it a year round spring? Does it currently have water running?

    Sad End to This Cautionary Tale, As Folks Start to Head Back Out Into the Wilds, Pls Be Careful

    I dunno, I can see how they came to their decision, and If I was in their shoes, I'm not sure I would have done anything differently. In hindsight everyone has 20/20, but I consider this an unfortunate accidents that led to the death rather than series of bad decisions. There are a lot of...

    Tire Deflators - What Do You Use and Why?

    I have some Staun knockoffs and from Amazon and just picked up a couple of sets of coyote deflators. The Coyote's are supposed to be the equivalent or improved versions of the Stauns, plus they're cheaper and made in the US. Don't have the Stauns so I can't compare directly, but I'm happy with...

    12V plugs and sockets that are not cigarette lighter style

    For really good small 12V plugs I've used RC battery plugs. Typically they really low resistance, rated for high amps, and are very small, especially ones meant for flying models where weight is a concern. For a while I was trying out Dean's plugs, which are rated for 60A (up to 100A peak) and...

    DIY Telescoping Lift for RTT on Trailer

    One of the problems with telescoping tube is the balancing the clearances needed to lift it without binding while maintaining a tight enough tolerance so it's not wobbling all over the place when you're sleeping in it. You could use a 4 bar linkage similar to this mechanism...

    AUTOWIT SUPERCAP 2 jump starter..

    I've had a supercap jumpstarter for a few months now and I really like it. It works slightly differently than a normal battery style jumpers, but it also seems to give more of a "boost" when starting that helps with some difficult to start engines. You do need to really make sure the...
