Are you thinking something like a regular ATX sort of supply? That might be an option, the +12V on those can be fairly sizeable. You may have a couple of options. First make sure you're above the minimum input voltage and can supply the power it'll work. My Victron says it'll work over an...

I mentioned this in another thread Scott but this same solution may work for you. You can run a AC/DC power supply into the input of a DC-DC charger. For example, I run a Victron Orion-TR 12/12-18, a DC-only charger. But when I have mains available I use a repurposed ham radio power supply...

Nothing wrong with 16 and 18 AWG wire if those labels are right about 3A load. Probably would be for 7.5A, too, although voltage drop could start to factor in on a very long run. An 18AWG wire with PVC insulation that's 72 inches long with 7.5A will have 0.30V of drop and around 7°C temp rise...

You do need bigger crimpers for SB120 and larger, although they don't need to be particularly special. For the PP15/30/45 and SB50 using the Anderson specific crimpers is pretty important for them to be reliable but the SB120 and larger are just regular hex crimps. To answer your question the...

Indeed Martin, in your use case using a temporary inverter as a fail safe is a fine way to go. No question better than dragging a generator around for what-if. I don't rely on the inverter solution but I do carry that AC/DC Powerwerx power supply sometimes for basically the same "just in case"...

I think we all sympathize. It's not a one size fits all answer. Using a DC-DC should be fine, although for 200 A-hr a 20A charger is a little light. If you run down completely that's still a 10 hour recharge idle even once you get all the kinks ironed out. To be honest the suggestion above...

If it gets you what you want it's fine, albeit with the extra complexity. You already have a decent charger in the DC-DC just my opinion the better effort is to figure out what's really going on. For one, that 9A might not be wrong. Have you verified that by discharging some and making sure...

Bypassing the DC-DC converter is technically fine as long as the charging voltage is well regulated to be 14.6V or lower. However the alternator is likely not going to be very tightly regulated and could be lower or/and higher than this. If you (or anyone) is thinking about this do NOT bypass...

@Martinjmpr, to your second issue with the lower charging current. What's the alternator end voltage and what's the voltage at the charger input? This is probably just simple loss in the cable. You'll see voltage drop with a run that long and there's nothing you can do about that other than...

If this is the correct manual: https://www.renogy.com/content/RNG-DCC1212-20-BC/DCC1212-204060-Manual.pdf The DIP switches seem wrong. If I read the chart right to get 14.6V you would have SW1 = ON SW2 = ON SW3 = ON SW4 = ON SW5 = OFF If I was to hazard a guess the controller could be...

Yes indeed, the built-in GPS in a modern tablet or phone is completely adequate. Devices for several years can use all major constellations with dozens of channels, so the limitation is GNSS function itself. Some devices can even do multiple bands (eg adding L2, L5, etc) and approach survey...

Agree with @undisider, don't use the crush crimpers in those do everything wire tools. The crimp shape I think is basically a standard Molex 'F' but the depth is longer. So if you have Molex dies for your crimper you might be able to do adequate crimps. It'll take two crimps of the same size...

I have an FT-857D. Also have an IC-7300 and a few FM mobiles and HTs. The 857, as well as the same platform 817/818/897 or 450, 950 and a few other Yaesu of the era are fine radios but I would caution you that they are growing long in the tooth so you have to cognizant of a particular unit's...

Tinning is not necessary. If it's stranded wire that the individual strands are tinned by the factory, that's OK and generally a benefit. Tinning in the field is not best practice. The reason to tin a copper wire is to prevent oxidation, which is 100% legitimate. Melting solder into a...

With a DC-DC charger you need to think in terms of power, not just voltage or current individually. A 30A DC-DC is probably actually specified as a 360 watt charger. The benefit here is that the input and output are not directly related other than total power transferred. You can put a lower...

The voltage drop is calculated but for heating it's not used. The 12.5V in the chart indicates the forcing voltage I assumed. I could put it at 10V or 14V. It doesn't matter for the temp rise. I include it only as reference so I can calculate a percent drop. In fact the simplified...

On iOS I have an app that does I think what you want. It's called Trail Tracker. It does display a map but if you're out of service or in airplane mode it doesn't need it. For Android I have one called GPS Logger that seems to do the same thing but I don't have much experience using it yet...

Fitting stock trucks is a kind of an interesting point. Take that post with a grain of salt since the limitations stock remain even with increased ride height due to such things as hitting the frame, cab mount, fender lip or pinch seam, unless along with lift you lower the bump stops to limit...

FWIW as he says 2005+ rims are ~5.25" backspacing while the 95-04 Tacoma would be ~4.5" from the factory. I went the other way, using 3rd gen 4Runner rims on my 2008 Tacoma. I did notice the handling changed, the turn radius feels a little larger due to the increased scrub radius. As far as...

This is an interesting point about fuse sizing. You say they put in a 2A fuse for the whole panel but the RJ45 is generally only going to be good to 960mA per pair (the highest power over Ethernet spec). You can't fuse it by adding up all 4 pairs because each individual wire could be asked to...
