Came for the "heloooooooo!" Wasnt disapointed

I run my heater on 5ah 20v dewalt batterys with a 15a 12v step down converter and I've never had a problem👍

Between AvE and David McLuckie, this Yank is thoroughly edu-mah-cated and entertained.

Your vids are great no bullshit you tell it as it is , you’ve explained how these heaters work perfectly I’ve learned a lot thanks 👍👨🏻‍🏭🇬🇧

I’ve got a 36v to 12v (claims 20A @ 12V output) converter - Downsol brand from FleaBay. Makita batteries are quite happy in series, my big battery saw is 36v as it uses two of these (5Ah) and this converter is designed for 36v input, so not under running a 24v converter. It’s got a large die cast case that gets warm when running 8A output at 12V (100w) so maybe this is an option - but you would need two of the battery adapter “shoes”.

Hey David! I think these are actually rated 10A output current, you were measuring input current. Try and find a 20A buck converter with a fixed output voltage, should be potted and have a heatsink.

I've done it with a 30 amp converter. With a 12 amp hour n18 battery it run a long time on a 5kw at full power

Every diesel heater needs a tool batter option adaptor setup. Hopefully makita Milwaukee and other tool brands make a tool battery operated diesel heater

Basically divide the quoted power rating by 2 for any of the buck converter boards. They are good but always under heatsinked for even half the rating.

I make portable diesel heaters in pelican cases and sell a bunch with dewalt battery holders, the 12 amp work fantastic and can get between 7-10 hours of usage in a 5kw unit. I use those big aluminum buck converters and a low voltage alarm for the lithium batteries.

hi great video you can get model plane voltage controlers up to 20 plus amps also try a lipo battery either a big 4 cell or a large 3 cell both will do the job

I'd probably use 3 or 4 voltage converters in parallel. 3 amps a piece. What are they like a pound a piece? The other thing that can be done is using the power supply with a cheap lawnmower battery. Find the resting voltage. Hold the resting voltage with your power supply. Once the glow plug goes out the power supply will bring the battery back up to resting voltage

Brilliant video thank you 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍

Hey I'm really into thinking about radiant floor heat from one of these.

You could possibly use a solar power controller to out put those requirements Have a cheap one i purchased off evilbay For about 20.00 us. Takes 30v from my panel and outputs about 13v to charge my deep cycle with an inverter drain.? Not sure but drains for my diesel heater just fine.

Hi David - thanks for all the interesting and informative films. Do you happen to know who supplies a quality exhaust and silencer for a Chinese diesel heater . One winter and the one on my van is looking very 😞😂😂

Thanks Again For Sharing Your Life Travels

That was fun to try! Cheers!

Ebay truck 24v to 12v DC-DC stepdown converter 240w 20A with handle an input voltage down to 18v and output 12v.

Can I request a video showing how to swap out the devil heater ecu for one that is compatible for use with the afterburner controller? Ihave the air/water heater version and need to do this mod but it's not quite a simple swapping of the boards as the connectors differ... Many thanks, great stuff as always!

ha!!! i killed one of those little boards.. in my endless no-start fights with my VVKB water heater at one point I had thought if i gave my heater higher voltage that my glowpin would glow hotter and the heater would Light off.. (my heater doesnt like to light off when its colder than about -2c) I gave mine 24 volts in and pushed 15 volts out.. my board looked similar to yours.. and same result.. the heater didnt light and the board smelled like Cooked transistors.... I never measured the current with my meter. I never got the chance it burnt up too quick..

That board I'd guess could peak a second at 10 amp but there is no heat sinking on it, heck even the 3amp buck/boost converters have heatsink of some kind. I use the Chinese rating of - advertising spec devide by half- I have a claimed 10amp board that gets pretty hot, 70v ish in and 17v out at 3.5amp. I have seen another KZfaqr use bigger boards but not sure of the exact current

What if you had a small lead acid battery that was charged by the buck converter? Would the battery supply most of the current spike?

Two resistors in series makes a voltage divider circuit. Online calculators for Voltage dividers will help you pick the two resistors you need to get the voltage you want. Add a zenor diode with the voltage desired for a cut off point to turn the battery off at a specific voltage. I'm sure someone here could draw you up a diagram for a simple circuit like I've described.

When the smoke was let out of the wee module, you were measuring ~7A. Am I right in thinking that was on the 18v lead to the module? If so, then the draw on the output side @ 14v would be a higher current - nearer 9A. Still should have been within the spec of the module right enough.

Have you thought about using a cheap solar charge controller to get the volts down to 14v

Brilliant man 👍😎❤️

AvE stylee?

If you access the hidden settings through the original controller it allows you to change the power from 12 to 24 volts

I started my heater on a 12volt motorcycle battery but didn't run long because it was only 14 amp hours you do need a continous source

Interesting vid.

also - whats the current draw on the pump in Amps..

Could you use enough TECs to have a module that produces enough energy to make it that you only need a tiny battery but it can self sustain and not need a mains connection.

as noted in other comments, get bigclive to help out on this, that would make for a very interesting video

Watching a few of your vids - I have a 2 kw unit - looking to run off Aux house battery (100AH) pulling Diesel from the vehicle fuel tank - any thoughts on this?

Can you run 2 in parallel (2 of each sets)

Dave a question not a comment have you ever tried to run a diesel heater vertically Instead of horizontally with the inlet up and the discharge down thanks

FYI: Voltage Range: 12V is 10.5-16, 24V is 21-32V. I've only tested 24V heater using a 7S li-ion at 29.9v.

if one estimates 18.5v on the battery and an amp of 7.5. then the out current will be 10.2A at 14V on the output. this is above 10A :) they did not specify where it was max 10A

the 20 amp ones work to run heater from 24v on eBay

I want to see if you can charge up the battery using peltier plates???

hi have 3 diesel heaters all not working one pump failed after a year the other 2 with in 3 weeks have one that pumps fuel downwards but when connected to the heater stops ,ticking nose ok can they be repaired they dont seem to last where do get yours from thanks

You didnt factor in the Chinese amp factor of -divided by 2 lol

Curiosity where do you get the afterburner control been looking all over looking for it the one that's made in Australia

Hi why can't you get the afterburner in the UK thanks

What happens if your diesel heater turns of while running full but the battery dies and it stops and can't cool down ? Or dose it turn of before the battery gets to low?

I tried a couple times to post a link to the voltage convertor I used but it keeps getting removed or at least I canny see it anymore

My 12v 4ah Hercules batteries work great.

Do a search either on eBay or AliExpress for DC-DC 300W 20A

Is running the heaters in altitude mode ok at normal elevation ? I find it a little cooler than on full normal mode ?

How do i miss this... HELLOOOOOOOOOOOOO

Hi David, if you ask nicely you can still get the Afterburner 😉

Such a great video, I'm sure van lifers have wanted to try this. What happens with two batteries to make the 10ah ?

Get yourself an ltc3780 module they run 10 amps all day long and only get a little warm ive tested the hell out of them modules

24v to 12v dropper out a wagon maybe?

I should do this with my Hercules 20 v 5ah battery

You can change the voltage on the original controller from 12v or 24v. Mine did anyway

Love your terminology “let the smoke out”, I’ll have to try that one. 😃

for science!

Put controller in 24 volt, technically 5x4.2v is 21volts is what almost every power tool battery is actually outputting it might trip the under-voltage in that mode but worth a shot!

but that's 200 ma at 18 volts,,, check the buck converters output

Just use a 14.4 v battery pack for the test. 3 x 18650 batteries in series will give you 11.1 v.

attatch a steel coil of wire to positive lead this will drop voltage

Put 3 of those modules in parallel

You wont a truck converter that takes 24v down to 12v

💅🏻 As Jim Lahey says ☟ ..Change it to 24v on the controller.

Always divide Chinese Specifications by two 😃😃

or a 14v battery!

12v or 24v you can set them, you know that

it shit the bed.

30w DC motor speed controllers are cheap enough

Put it through a cheap solar controller

Most solar charger controller would do it

not for long im gessing

I don't think that battery can handle it

Change the system to 24v

And it has fucking died lmfaooooo

I design make and sell those battery connectors :-). I can do a wayyyy better deal than the Chinese :-). Let me know if you want some!
