Every diesel heater needs a tool batter option adaptor setup. Hopefully makita Milwaukee and other tool brands make a tool battery operated diesel heater
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 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”.
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 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.
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.
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 😞😂😂
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.
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
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!
all devices are filled up with this magic Smoke in the factory.. the magic smoke of different smell, color, and density makes parts work differently.. when you let the magic smoke out by rupturing the part then it no longer workie :) :) ha!!
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 RU-vidr use bigger boards but not sure of the exact current
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.
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.
Agreed, if the battery was fully charged that would be 20V, so 10A at 14V, so technically within the limits of the device; however, the 8 pin MOSFET packages are not usually rated to that current, I would have expected to see a D2PAK style mosfet there.
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
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.
So that is something I'd like to try this year. I just need to do a shopping list of the parts I'll need. TEC modules (10 or 20), heatsinks for the cool side, square pipe to attach them to and something that will take the power they produce and make a useable voltage to charge a battery and run the heater.
Quite a few step down regulators on the internet with variable voltage you could use. I'd assume you wire them up in series to get the most sensitivity or om groups as you want a pair of them around the same temperature zone else their act as a resistance.
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?
@@DavidMcLuckie my controller was on 24v setting when I first got it, just faulted out on low voltage as I was using 12v, it wouldn’t surprise me if the heaters can run on 12v or 24v
@@906MediaProductions while that makes sense in most cases what about a winter storm where the clouds and snow make solar not effective. I was thinking the exhaust might have enough heat and cold to make keeping the battery level up possible?
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?
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
Yes. But I can't remember which way up I had it. They do work but there is a possibilty of a small fuel leak from the burn chamber flame front hole next to the glow plug.
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
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!
@@DavidMcLuckie i am confused on my controller in the advanced settings there is an option for 12 or 24 volt input, if set to 24 volt wouldn’t the controller or ecu then be the regulator for motor and other i assume in 12 volt mode to control speed its lowering voltage to fan motor to say 8 volts, what is that setting for then?
@@DavidMcLuckie cool, that converter thing ended up being quite the deal, other new ones were about 70 quid and it's more like a regulator it makes a steady output voltage when the drill battery went between near 19v down I let it drop to 16v( to be safe so it would still charge) and the output stayed the same
You can set the ECU to 12v or 24v version. But the fuel pump, fan motor, and glow plug are all voltage dependent and need to be matched to the voltage you are using.
@@DavidMcLuckie Only the ECU, That makes no sense, i thought the whole system would be 24v once set that way So i need a 24v and a 12v to run it at 24v, you sure?
Hi everyone... thanks kindly for showing interest in UK design and manufacture of these battery adapters... with David’s permission I’ll pop a link to my eBay shop so you can take a look. I have DeWALT, Makita, Parkside, Worx and black a decker ... I’m always working on designing and making more! ...
