    Troubleshooting Renogy 20A DC-DC converter?

    Sounds like a plan. There is a reason, as you've discovered, that alternating current replaced DC for distances. Smaller wire. I've discovered my camper's 45 amp converter (battery charger) does not have a lithium selection, and can provide limited charging voltage . It does output too high...

    Troubleshooting Renogy 20A DC-DC converter?

    I thought of one other possible plus to the portable inverter system. If your charging system does not output a high enough voltage DC, the inverter becomes a constant 120vac voltage supply that draws a few extra amps from the battery when needed, somewhat like a DC-DC converter. I connected...

    Troubleshooting Renogy 20A DC-DC converter?

    Congratulations on Dave’s advice and now having a functional DC-DC for one of your batteries! If I already had a DC-DC charger installed, I would not do the direct wire method since that seems more than enough amps based upon your past experience with that battery. Yes, the brown cord from...

    Troubleshooting Renogy 20A DC-DC converter?

    TL/DR: Try direct connection charging. Remove the wires from the DC-DC, connect them together, then look at bluetooth screen. I’ve been following along as my situation is similar. After my seven-year old 100ah AGM decayed, and lifepo4 prices decreased, I took the plunge. I’ve been using the...

    DC-DC charger as an alternative to generator?

    Yes, the amps seen on your bluetooth screen is the sum of amps in and out. Negative number means being discharged. Disconnect loads, and it is just charging amps coming in. That would be handy for the following charging test. You have already verified 14+ volts from your vehicle at the DC-DC...

    DC-DC charger as an alternative to generator?

    TL;DR. The last three paragraphs are important for me. Crickets. Still traveling Mrtnjmpr? I just purchased two of the Elefast batteries rruff posted above. I now know that the voltage seen on the bluetooth screen on mine is indeed the voltage seen from the charger. Your screen shot showing...

    DC-DC charger as an alternative to generator?

    Has it worked before, or is this a first time use? Do you have an activation (really small wire) connected to your vehicles 12v or another really small output current reducing wire connected somewhere? Possibly disconnect the solar panels and see what happens. Don't try the old jumper cable...

    2021+ f150 aux dual battery for fridge???

    Has anyone used a lifepo4 in an engine compartment? When my seven year old AGM house battery dies, I planned on that battery box to become vacant because of heat concerns.

    Carb at high elevation

    Thanks for the link to the carb cheater. I thoroughly enjoyed the video, and learned a lot. I have carbs, but no dramatic altitude changes. The non-metallic air bleed plate used could help keep heat away from the carb, also. I've had good luck with a short piece of fuel line with a screw...

    Carb at high elevation

    I have old memories of driving across the USA on fairly new and under construction interstates while burning leaded gas. Slight and not so slight "rolling coal" seen from tailpipes when hitting the Rockies. I saw drivers removing air filters and other methods to try to lean. What spot and...

    DC-DC charger as an alternative to generator?

    Back to the first post. Since your Martinjmpr jumper cables charged your batteries, it seems you have sufficient alternator charging voltage at idle to provide some battery charging. Some, determined by monitoring. All alternator equipped vehicles I've owned, at idle, attempt to charge the...

    DC-DC charger as an alternative to generator?

    In the fifties, dc analog ammeters, then idiot lights, and finally, dc analog voltmeters from the factory, none of which are very valuable when both DC voltages in the tenths and amps are important. It's never been easier to obtain both by clicking on products manufactured thousands of miles...

    Basic 12v wiring question

    Yes, sometimes the switch(s) are placed in the neutral or negative wires. Old vehicles points systems and non-USA things were my first exposure to that decades ago. Yes, it does seem that you need to move the mismatched wires directly across from each other. If you remove the two mismatched...

    Best Primary Battery - Jeep JK

    I've used marine deep cycle (not marine starting) for both starting and house batteries for years with no problems on V8 gas engines. Engine starting currents (amps) have decreased from years ago due to gear reduction starters. Knowing starting amps helps to decide. Deep cycle batteries also...

    The Dometic CFX3 Mega Thread

    Lemesee, the manufacturer or reseller never thought to test it in that environment? A fridge meant for possible camping? Send me one and I'll test it and spread word to my about five close friends and post the results here next year.

    Tapping the Gas Tank on a RAM HD

    I did something crudely similar about eight years ago on an Econoline for a different purpose, siphoning. Blow into the hose, slightly pressurizing the tank, and that would start siphon flow. There is a shutoff valve, and the fuel line is coiled behind and below the filler and access door. My...

    Lipo charging setup for the bed of my truck

    Dave in AZ, using the 7 pin may seem a little crude. It's all about charging voltage. I have two vehicles for camping. My Silverado with smart charging will maintain about 14.5vdc as long as the park or headlights are on. My van's dumb alternator's voltage varies between 14.1 and 14.7vdc. These...

    Lipo charging setup for the bed of my truck

    Does your truck have a 7 pin connector? I run a 12v fridge and charge a 30ah lifepo4 in the back of my truck while traveling via a 7 pin female connector with only two wires attached to the male connector. The wires go through a gap in the tailgate while closed. The vehicles I'm familiar with...

    John, if you're still here, is your barn floor concrete? I've raised the ceiling by lowering the floor.
