Yeah I’m emailing the manufacturer back and forth and will probably get a slightly smaller pulley. I think other vehicles they put these in must have a higher idle. But in park once warm it’s 550-600 RPM’s and 500 RPMs in drive and that seems to be completely fine and normal for these 4.7L...

Yeah at warm idle in park it’s like .4 gallons per hour. V8 4.7L toyota. Not the most fuel efficient but it will last 500k miles

But then the alternator is increasing the fuel and for maximum efficiency I’m ramping up the RPM’s of the car a little bit to get close to the 270 amps of the alternator. it’s at least 1/4 to 1/3 a gallon/hour at the very lowest RPMs and that’s without a big alternator load, currently only used...

In a SUV so the best I can get (that has high amps at low RPMs anyway) is 270a 12v. I wish there was room somehow for a second alt. It can do 200 amps at idle RPMs and I’m planning to work up my charge to 150 amps during idle and 200 amps while driving. This is in the vehicle mounted forum and...

I just found an app to estimate angle of the panels and where I’m located and it looks like ideal December angle for me is just under 65 degrees and if I drive further north in the US it could hit 70 degrees for optimal angle. Pretty wild. Summer it’s 17 degrees where I’m at. But 25-30% of...

Sorry, I did mean WH a few times. Yes, I did mean watt hours. Edited my initial post. And I meant 100 watt hours on a completely sunny winter day. Judging from the wattage I’d get when the sun was at a similar angle when I installed the panels. How much would temps play into the output? I saw...

So I finally decided to dive into solar this summer now that my power uses are so high (65L fridge/freezer, tons of camera/drone batteries, pressure cooker, 3D printer) and a 100W panel kept up with the 12v fridge uses while I was gone on extended work trips. I decided to put my 2 200 amp 12v...

https://www.progressiverc.com/products/isdt-p30 I’m guessing I screwed up and used a charger meant for an isolated setup with a non-isolated setup (the renogy). Polarity is fine or else I wouldn’t be able to operate the second charger from one of the sets of wires. A bummer because the...

Just to clarify, in tests I was only using a few amps on charger number 2 so total amps was not an issue. When I put in the new alternator a few months ago I upgraded the OEM 2 and 4 AWG cable to 4/0 cable everywhere in the engine bay (positive to starter and all ground points). Alternator is...

Hello! I’m looking to charge my 400 AH battery bank with a second charger while driving. Currently I use a 50 amp renogy DC to DC charger/MPPT. I’ve upgraded from a 150 to 270 amp alternator to increase the alternator charging (I have high load stuff like 3D printer, pressure cooker, tons of...

15* amps as I’m switching to 24v soon. I found a singular buck or boost only 12 to 24 or 24 to 12, I just want a solid consistent 15 amp 24v out because several of the 3D printer components could negatively affect the printing by any change in voltage. I have a compact $60 DC fpv charger that...

Trying to run a 3D printer off of batteries, I currently have them in 12v configuration but will be switching to series for 24v. I can’t find specs for the voltage on the 3D printer I have to see if it would be okay with peak charging voltage for LiFe so I’m looking for a steady 24v output...

I have 54 lishen 18AH cells I’m planning to make a 6S9P setup with, delete the starting battery, and use some resistors with the alternator to slightly increase the charging voltage, as many have done in car audio groups. Doing all this to 1: charge the LTO bank faster than most available DC to...

What's the highest output options for a 12 to 24v dc to dc converter with a charge profile? I'm in the process of figuring out a setup for an 11S 24v LTO system. I was hoping to take advantage of the faster charge times and use a bigger DC to DC converter (currently use a 50 amp one with my old...

Hello! A little over a year ago I bought two renogy 100AH batteries since I needed something ASAP for work and Battleborn would have taken too long. In retrospect I wish I would have risked it for the Battleborn. I recently disconnected my battery system to insulate the Renogy batteries and...
