Great video again Keelan 👍
So many people don’t spec the cables for the volt drop when looking at cable run lengths.
Pretty happy we did our build before the regs came through.

hey matt your the winner of our giveaway mate! flick us an email at sarahkeelan.travels@gmail.com and we will flick your prize to you! beware of scammers me and Sarah will never ask for bank details or money!
@@SarahandKeelanTravelsthanks guys, email sent 😄
Voltage drop completely depends on the current draw. To calculate the voltage drop you need to know how much current is expected to run through the cable.
Thanks Keelan and lassie from one qualified sparkle to another - I’m three years into my Hilux & aluminium canopy build as a grey senior and luckily a veteran Avionics technician so I won’t be taking shortcuts like a Boeing executive - thx for the update on new regulations and your passion for doing it right - I’ve installed an Amptron/RedarcEngel/Kings system and now adding Sureflo water pump and monitor, solar features and air compressor - it’s taken me this length because I’ve prototyped each stage and made appropriate changes for efficiency and safety - heavy duty cabling, circuit breakers and strong relays are my standard mantra - good luck with the new drone.
What squadron mate? I'm an ex 75SQN avtech.
@@----.__ I was a only a civie for several years bu my father did Aussie airforce as a LAME then civie like me.
@@johnnumbat9782 Ah, no worries. Civies usually refer to us a LAME's and raafy's usally as avtechs so I got excited! Thought I may have known you for a second there!
Stay well all the same mate.
if your canopy is not a living space, ie somewhere you sleep, these rules do not entirely apply, ie the battery sealing in a box issue.
"SKT, you guys truly nailed it with this video! It's refreshing to see such a clear and no-nonsense breakdown of 12-volt system requirements. Your ability to make complex information accessible for everyone is impressive. Keep up the fantastic work!"
As someone who has lived off grid for 10 years and built my own solar set-up,i can say he's 100 percent spot On,
Same here been off grid for bout the same time.
As a 70-year-old electrician, this guy is spot on. He knows what he is talking about. Thanks for bringing me up to date as well.
I almost didn’t watch this because I am so used to the “two genetically gifted people doing a lap” TH-cam channels talking about things they have no clue about.
I shouldn’t have judged, this was so well put, so genuine, and a perfect explanation. Subscribing for sure.
It’s amazing how many of the new rules are almost just common sense. (Other than a 20mm vent for a Lithium Battery haha) 😊
Fat chunks can be genetically gifted too 😊
Thanks
Thank you!!
Dude you are amazing, this has just saved us a fortune, your no BS explanation is why you are so loved. Thank you and your sponsors should be proud of the relationship.
Far out what an amazing comment, glad I can help! Made my day! 🍻🤙🏽
Looks Stoic Scottish to me.
@@SarahandKeelanTravels Hi Keelan. Just a question about solar. Does every panel actually have to be fused inside or just every string. Surely if you have panels in series or parallel you don't have to come back into the van to a fuse then back out.
@@TearingTheVeil-ze4rx That's exactly what he was talking about. Every Panel needs to be fused separately. You don't have to bring a cable back out. Just connect them inside
An alternator obviously only charges when the vehicle is being driven and is not the primary charge supply for an off-grid system the solar takes that role and most of the time its only a 6mm cable feeding the vans battery supply , So its really not that important or even needed with the right solar system so don't go designing any off-grid system with the alternator wire in primary focus . Most vans have the batteries mounted in the front storage compartment so voltage drop shouldn't be an issue with a new system , The wires for my off grid cabin are like 50ft long ( from panels through circuit protection to the batteries ) on overcast day the system charges at about 13.4 v which is fine and under full sun up to 14.4v ( depending on charge state of batteries ) think its pretty safe to say my system is efficient . ✌️
Don’t forget the front boot of older vans.
Our setup is a control panel that has dcdc and 240v chargers, along with a fuse panel above the batteries, which are attached to the floor of the boot, with a run of less than a metre.
The front boot is gal lined and double vented.
Using 6b n s wiring through out.
This is literally the only video on TH-cam explaining this. Cheers to you both for this video it's really helpful. Can you possibly do a video explaining how to mount the batteries internally with the gasket and vent setup?
Hey guys found your channnel today and literally sat on the couch all day watching it
Your 12v knowledge is unreal and the way you explain it is so simple
We’re hooked u guys, great vids 👍
Thanks SKT for the no BS overview. We are looking at a new camper and still need to work out where to put the electrical. I’m loving your idea of the external battery bank/box. That could work so well for our trailer too. I appreciate you making this video as I think you will have saved us so much time, frustration and money. Plus give us some solid information to have an informed conversation on the topic. THANK YOU!!!
Hey thanks for the no BS video. I have a Jayco 21.5 Silverline Outback van that is really struggling to keep 2x120 amp AGM batteries charged and they’re only 2 months old.
After looking at this video I’m starting to get the impression I need to go back to the drawing board. This video is a great starting point - cheers
Many thanks! I actually bought a lithium battery today to convert from AGM in the back of my Ranger. Everything is fused before and after the charger. I’ve also been advised to add a shunt between battery and accessories. Cheers guys great channels and enjoy your travels.
The shunt will allow you to monitor the state of charge of the battery (see how much fuel is left in the tank). Shunts don't provide circuit protection like fuses and breakers do.
Shunt goes between the Negative terminal and the charger/loads. You want it to measure both charging current and discharging current.
Thank you so much. Concise & to the point. We have put a deposit on our 1st van & pick up next June 2025 so you have given us lots of pertinent questions to be asked. Love your work mate. We will definitely keep following you 👍
One sparky to another your video was fantastic and so easy to understand for people that don’t understand. Legend
Thanks for clearing up on the sealed-vented battery box . Its made my placement in the cab perfectly.
I have argued with people about fusing the solar input, many many times, this confirms exactly what I have been saying. Thanks for clearing it up.
Yeah I would never have done it, but about to set up a system in my campervan. And will be definitely doing it, as well as isolating each component.
It's always been the rule if you parallel more than 3 panels/strings.
I watched a million of these to the point where it's beyond redundant. And boreing but I still appreciate a person who is knowledgeable and catches the issues that end up going on the customer.
Just love your passion. Hard to find blokes like you that are passionate about there trade and just want to help other. Cheers mate for sharing
Thanks legend!! Yeah mate I love it aye! Could talk power all day long! Glad I can help! Makes me feel useful!! Cheers for watching 🤙🏽
I was thinking "oh god, here we go, this sounds bad" but this was one of the best videos i've seen in a long time. Easy to understand for someone like me who thought this stuff was confusing. Top work mate 👍
bought a camper trailler in March this year and there was a delay in delivery due to the need to externalise the lithium system. Previous campers had it in the storage in the internal 'lounge' area. So spot on there. lost a little external storage to pick up some safety and internal storage
Legendary Cus. 👍🏻
I am an auto sparkie in Nz. I have just gotten a bus 2 convert and busy designing my 12v side. The lack of straight answers has been driving me nuts. Even tried downloading the new Regs but still yet to come across real specs and requirements.
Many thanks
Thanks bro, I'm a sparkle in nsw as well and have been in the solar industry for more than 17 years and I agree with all y ouve said! Goodness, no BS!! Phil
Well done, very informative and also to comply with current legislation. It's refreshing to hear wiring losses and what to do to overcome these losses
As a sparky/instro for 20years you are spot on Vd is a huge thing, I’ve done a heap of boats and van setups and get people criticising my work because they think I’ve used to big of a cable and I fuse every run. I calculate all my installs for Vd and select the appropriate cable to suite the load. This 12v field has to many unlicensed cowboy in it the ESO needs to start regulating it.
Mate a lot of full ticket sparkies don't understand voltage drop even in their core business.
Get them into ELV systems and DC and they are totally out of their depth.
.
Time and time again, across all fields, people are too stingy, to do what it takes and pay for big enough cable.
.
You keep doin it right.
It's not your sparky ticket that makes you do it right, it's your personal desire to do so.
@@soundman6645 i completly agree. I m one of those unlicenced cowboy but i did calculate the voltage drop and followed the AS 3000. So if you want to do things right, it s not rocket science to do so. Yes, It does need a little bit of research.
@@AlbanCoville you keep dpin it right brother
Another very informative vid mate...can't wait to share this with the rest of my family who all have off grid vans.
Hey guys, love your work. Keelan, good to hear that you're promoting AS3001 Regulation Compliance - You are soooooo right about the hoards of Cowboys in the Rec Vehicle Industry.
Just watched all your 12v videos. I thought I had a pretty good understanding of it all but jeez I just learnt a lot! Thanks for the great videos!
Nice job Keelan, as a fellow sparky I sometimes want to scream when I get the old "Lithium batteries dangerous" comments. I just point them to videos like yours so they can gain some knowledge. "SKT" keep on Living Barry !!!.
evs have lifepo4 batteries and burn daily0--china has 21000 reported ev fires a year from lithioum lifepo4, imagine how many are not reported
As an RC enthusiast, that comment pisses me off too. Yes, lithium batteries CAN be dangerous. WHEN something goes wrong. They need respecting, and they need to be handled and maintained correctly, as long as they are, nothing wrong with them whatsoever. Sadly the surge in lithium devices like scooters etc has suddenly turned everyone into a battery expert just because a few badly maintained or damaged escooters exploded.
Like many, I use L-ion tool batteries and not had an issue, but you do see issues with cheap E scooters or cheap E bikes. I feel it's worth spending that extra money to buy a trusted reliable brand when it comes to pretty much anything really.
Lithium batteries aren’t dangerous lmao - people are more dangerous than batteries
@@jamesaustralian9829and electric cars go into thermal runaway all the time
Mate I sometimes question why I keep watching the videos but there’s no denying the passion in your trade and to make it simple for the public to understand! Well done SKT! 👏
Sounds like you’re loving it.
So why are you questioning why you keep watching?
Little bit of a correction with the habitual area. They can be mounted in a habitual area but must be in a sealed gas tight metal container which is vented to the external environment. Under beds or couches, is still considered a habitual area. But like I said. Must be in a sealed metal container vented to the outside environment.
Solar panels with an array of more than 200w must be fused.
@@TorqueKit Err, the word is HABITABLE. not inhabitable, habitual or habital.
The enclosure does not have to be metal, please show us by referring to the standard and the specific section numbers, where it specifies metal enclosures.
Thank you so much! I don't subscribe to many channels but yours I subscribed to without hesitation. You have saved me a small fortune. Thank you!
Best video on TH-cam for this subject, nice work guys.
Thanks legend! There’s others that just read the rules and that’s it, no practical guidance. Hopefully we have given the people the tools to go make good decisions now!! Thanks for watching
I can never understand anything solar but u explain it clearly and for normal people. Thankyou!!!!! ❤ from Nowra nsw
Thank you for quoting the actual regulations, too many people just repeat things they have heard without actually checking the regulations.
Being only a newcomer to the caravanning scene I was completely unaware of these rules regarding Lithium, good thing though, my batteries reside in a box on the van drawbar so nothing to worry about 👌
Great video, easy and straightforward explanation of what's required. Cheers from the golden mile 👍
What a great video - as a non sparky I fully understood the logic. With the batteries mounted outside you're also recovering valuable inside space under bench seats which can be used to store other things. SKT ❤🔥
Great video. I hadn't known the solar regs had been updated. Being an ex sparky/elec eng, it's great to find someone who actually knows what they are talking about.
Solar panel capacity and volt drop also well covered
Wow in Australia they teach critical thinking and common sense, unlike here in America. I can't recall anyone in the States talking as much sense as this guy. Great video ! 😊
Why do you speak in general? Every country has r3t@rds!
The price you pay for freedom.
We fund our school system better is my guess
Also in America they have a lot of super criminal Solar companies, the reason why they don't tell you the truth about Solar. And the reason why many Solar companies are going out of business. People in America don't trust Solar companies.
The laws of physics are the same regardless of where you live, but the laws around safety are vastly different. I don’t have an explanation. Welcome to the human race I guess.
As a guy who mows lawns I say this is 100% spot on
Another good Skt vid. These new laws really affect me because I was just about to tech screw my lithium batteries on my kitchen bench.
Better to use plumbers silastic because it's in the kitchen. And zip ties too.
Keelan - Wow! Talk about perfect timing. Last night I watched a video by Ronny Dahl about Dual Battery Systems ... "Most People Get This Wrong." and the gist I got was exactly what you said about locating the lithium batteries close to you charging system. Less wiring, distances and better efficiency.
What impresses me the most about SKT is your passion for the consumer and the challenge for manufacturers to think of us not just themselves, in fact I just setn a request to Urban Caravans for a quote to build us a rig. Thanks Mate.
SKT
Thanks Keelan for very informative info.
We are just starting this process you and Sarah have embarked on.
Many thanks to itechworld too for the great savings..
Good video we are getting a new van around December and i will taking note of where the cables are and there sizing, i have had some experience with my camper trailer and a Enerdrive 200amp battery install with 2000watt inverter and voltage drop.
Thanks again for a good video
what ticks me off with the whole motor and caravan industry is when I purchased a caravan in QLD and went to get it registered in Adelaide, I had to go for an inspection, on arrival I asked if they wanted to see the electrical and gas compliance certificate, NOPE, I paid $75 for a 5 min inspection, all they cared about was if it wasn't stolen, had a VIN number and the reflectors where in the right spot. my 12v was less than average which i have now fixed myself to a higher standard.
And stamped vins... is that a 4 or a 7
Thanks for the info on individual solar fusing. I recently built a camper with an unfused panel on the roof (wiring is capable of handling a full short circuit current with the wire size used and nothing flammable within the wire paths). I'm going to add an extra panel and fuse them both now!
I'm currently wiring up my 24v system and the main factor for keeping the wiring short for me is the cost! crazy expensive if you have to run 90mm2 wire from one end of your van to the other, all adds up in cost and weight very quickly.
- 24V is a secret to saving $ $ on copper - 48V is even better. (though in the interests of safety a 90mm2 power "bus" does get current from tip to tail without too much problem.- even jumpstart someone off the tailend 350A Anderson, though it costs(once) to install 15 metres of hooge copper..)
Well, with 48V systems you can just run 35mm^2 (2 AWG) and not worry too much about losses. 5000W @ 100A is a lot of power. 50mm^2 (1 AWG) for long cable runs if you are really worried and actually intend to push 5000W.
90mm^2 is total overkill in a 48V system. A lot of unnecessary weight and bulk and cost. No safety concerns, you obviously fuse the cable for its carrying capability.
-Matt
Keelan… 12 months ago I dropped in 2 itechworld batteries to replace our crappy heavy and dead agm batteries.. Works like a charm and yes I did use your discount code. Many thanks for for these 12 volt vids… 👍
Good video 👌 As an ex Electrican & with decent (Lithuim Ion Cobalt & Li-Ion Phospate battery experience) i would also strongly suggest using a "Metal Battery box" enclosure (not aluminum, im not assuming you have used aluminum but just making others aware of this) and having the 20mm venting pipe also made from Metal. Do not recommend PVC !
If Li - Ion Phospate cell/cells (Lifepo4) do ever internally fail, yes there is no violent thermal runaway with shooting flames but the LifeP04 cells can be subject to "extreme tempertures" & extremly hot smoke/gassing when a cell faliure occurs meaning an Aluminum Enclosure could potentially melt or if using a PVC 20mm gassing vent pipe (for example), the pipe could also melt then catch on fire whilst trying to vent. I believe lining a metal battery box enclosure in Fibre cement boarding or other high temperture resistance products & using appropriate high temperture resistance adhesives would be highly beneficial. Using a 20mm "Metal conduit" with appropriate metal bends for venting purposes would also be encouraged. I mean at the end of the day its where the family sleeps & who needs a potential fire taken hold of ones caravan/camp trailer, potentially when everyones deep asleep in which this risk can be easily reduced in the planning/constructing stage. (As suggested above) Im loving the fact that your batteries are on the OUTSIDE of your living space. (Added safety for sure) Eg The Voltage Drop is so important in a extra low voltage (12V) installation. An Excellent point you shared 😊👍 Cheers for the upload 🍻
Note - As an example : i use a ammo can (fibre cement lined with high temperature adhesive & vented) when storing my R/C Lipo batterys. Same principle applies but obviously Lipo cells are far more unstable than Lifepo4 Chemistry.
Mint video mate, heaps of information, a lot of helpful solutions, no blabbering on, good on ya! cheers
Love your public service announcements SKT! Keep up the good work!
I don't have SUV yet or 12v system but I loved how he went straight to the subject, no bull.
Mad respect.
Mate you two rock and providing such a valuable social service as well as entertainment!
If you wanted for precaution sake want to include a gas isolation box, do you have any direction on where to go?
SKT
Keep the good vibes rolling!
Thanks Keelan. Your explanation was brilliant and saved us a shitload of coin, planning and keeping the faith in our manufacturer.
Cheers for the episode.
Seems like some of the regs make sense, others seem like they adhere to more universal reg rules of making little sense 😂
I struggle with the logic of needing to vent batteries if there is a 240v input but not if there isn't.
Caravan 1: Lifepo4 batteries with 240v mains charger and 15a mains input = seal/vent?
Caravan 2: Lifepo4 batteries with no mains charger. 15a mains input only runs 240v circuits. 240v and 12v totally separate systems = seal/vent?
Caravan 3: Lifepo4 batteries with 12v charging only. No 15a mains input = put the batteries anywhere?
Quite aside from the fact that if lifepo4 has entered a run away state, venting gasses for the short period of time between run away starting and a pile of ash seems pointless. Lifepo4 batteries are sealed so are only going to vent if something has gone badly wrong. In that instance 20mm opening with no pressure differential isn't going to do much.
Have I got the wrong end of the stick here???
Do you know why the 15a mains input is the trigger?
When there’s a 15A mains input then it falls under the Australian standard for portable powered structures.
It’s like this because the structure/caravan is then connected to the grid. So it’s possible that faults can back feed into the grid
The 15A connection being the trigger for falling under the standard is clear enough. But it seems that these new regs are deliberately targeting battery systems rather than battery systems being unintended collateral damage. Given the battery is most likely 12/24/48v it'd be hard pressed to back feed a voltage or current through the mains charger (it's only connection to the grid) that would adversely impact the grid which runs at kv. If back feed was the concern, putting the batteries outside or in a box won't avoid that. It still means that if there is no 15A connection to grid, you can have the battery anywhere you want but if there is a 15A grid connection the battery needs to be sealed/vented. Seems a bit strange.
@@DW-10I believe that the regulation should apply to both and it's likely to catch up eventually..
LiFePO4 chemistry technically doesn't burn but the gases released in the event of thermal runaway are toxic and include plenty of hydrogen which goes 💥
In Germany a guy that had LiFePO4 in his basement had his house turned into splinters and rubble yet there was no fire.. people that claim LiFePO4 chemistry is 100% safe, turn their noses up when they hear this and simply fob it off...
I'm under no impression that Lifepo4 batteries are 100% safe. In the event of thermal runaway is a sealed box with a 20mm vent port going to make a material difference?
@@DW-10 The regulators have to make a living sometimes 🤣 so they justify their existence by updating the regs..?
It would certainly help initially with the venting of the gases "outside" the space the people are in
Very practical advice. A fourth consideration worth mentioning is that the fuses need to be correctly rated to protect the cable and any connectors etc.
Great explanation. Love the raw honesty.
With out even knowing the regs I have complied with all but one (individual fuse each panel) just by using common sense. I can isolate the panels and the batteries from the main electrics. Great video, thanks. I will be fitting individual fuses when I get home. 🙂
You are right to follow the electric car manufacturers and put the batteries outside the human spaces. The issues with all batteries, even Lead Acid, and LiPo, is that the combination of high current and battery chemistry can get VERY HOT, when things go wrong. I have had a Lead Acid battery blow the side off, spewing acid right across the engine compartment, when it was shorted. All of the Lithium, and Sodium (when it arrives) batteries have the potential to get hot enough to melt steel plate, and set alight to Aluminium plate. Protection circuits are good and will keep them mostly safe, but they cannot protect them from damage. PUT BATTERIES OUTSIDE.
I am a registered NZ Service tech, with full Electronic qualification, and 50+ years of experience. My current experience is with safety around disposing of Lithium batteries, and their use in being charged by solar panels, to drive Energisers.
Only some of these batteries that I’ve seen are fit to be outside. Namely Itech and Baintech. The rest have a lower IP rating so need to be in an inside space. There are new boxes made that have a sealed top with external terminal posts and a vent tube which I still believe the vent tube should be made of something more substantial but otherwise are compliant.
@@paulhunter4413 They crux of the battery problem is not the battery chemistry, it is the instantaneous current they can generate. This is where the heat comes from. I have yet to decide how to contain batteries, plastic is too flammable, and metal that holds on to the heat can be a issue itself. Steel mesh underneath is the best solution I can think of.
Except for vented batteries, they can all go outside as long as the connections are coated.
Thank you Keegan - SKT. The vid was super interesting and informative. You said you were going to explain things in layman’s terms and you did. I am a complete novice and was able to understand what you were explaining. Absolute ripper segment. Thanks again.
We swapped out our agms for the iTechworld batteries early last year, before the X range came in, and we still couldn't be happier. Twice the storage and a third of the weight. Your videos up to the Cape showed how resilient the batteries can be. Thank you legends.
@@noname-nd8ec ok, I d 10 t. Did you not pay attention to this and other videos about LiFePo4 batteries?
@noname-nd8ec can you please show us iTechworld batteries exploding? Thanks
Also did you even watch the video?
Once again, you've made the "troubles" straightforward and easy to understand. Thanks
Non inhabitable ??? Whoops. lol
Don't forget people, an Arc Welder is 24v and upwards from 50A, A battery bank can supply hundreds of Amps at 12/24/36/48volts and up to 300v or 400+v for House type of Inverters.
Fault current ratings are used on industrial battery banks systems. Last one i installed was 9200A.
yeh too many people are unaware of the massive fault currents possible and the consequences of failure.
Yeh we commonly weld with around 100 amps, then conside even the average car battery will produce 300 or 400 amps short circuit.
SKT at 19 minutes, thanks for the information as I have just recently updated to lithium myself, cheers
As a qualified Auto Electrician and Electrician. Many 12volt set ups should be using quality High Rupture Current (HRC) fuses. I do for my DCDC battery charger.
Yes, I wish to install a dcdc charger. I already have a relay for it from my main Lead Acid battery, so it is automatic... if that is allowed, I noticed now they are placing a switch on these devices that is a once only turn on for the device.
The problem is that anyone can bypass anything. I view that these devices are extremely difficult to open however I have a hacksaw blade and Zero electrical knowledge.
Boom 💥
Thanks mate, excellent content and well presented. all the best.
Michael.
As another fellow electrician i dont agree it is perfectly safe to sleep on top of a large storage system..there are other faults that can happen besides a lithium fire. Simple loose connections could cause i fire ride under neath you. I would not even have my control gear under my bed.
I've seen a video where an overheating lithium cell vented, it's basically like a bomb going off, shrapnel everywhere, it's not just a fire risk.
So you can sit over the massive storage battery when you driving, but you can't sleep over it? If you would get trapped in the car after the crash and battery pack would get damaged it is still legal.
@@LookMaintenance Did I miss something, where does it say it's illegal to sleep over power cells?

SKT Great video as always guys. Good explanation for those that are not electrically minded. Plain English is what is needed more within technical explanations, well done.
I agree with pretty much everything I've heard up to the 15 minute mark, as far as I've listened so far. My query would be that the intention of the "not in a habitable space" clause is so that if the battery does go off, it isn't going to turn the living area into a raging inferno.
I could be wrong, but I dont think people understand what would be required to thermally contain a sizeable battery bank in thermal runaway. Sealing/gasketing is one thing, but firewalling is an entirely different thing. You may have a sealed compartment under a bed or lounge, but I bet you dollars to donuts, the first time one of these things goes off, it'll make a mockery of that "compliance". The temperature, burn time and non extinguishability of these products is a phenomenal. What are your thoughts?
AND it's not just Lithium that burns ..... good old lead acid will explode and burn under fault conditions.
No way I want to be sleeping on batteries.
I wonder if housing them in a metal case that if ignition occurs could be filled with water to submerge the batteries. Of course, the trouble then is the rest of the time, any water needs to easily escape to prevent rusting of the compartment.
@@geoffsmith82 That is a very bad idea. The Lithium would react with the water and create a mix of hydrogen and lithium oxide, which is highly explosive.
@@herzog1000 It is actually the recommendation for laptops on planes if they catch alight. To poor a bottle of water over the laptop.
Putting the lithium batteries outside isn't such a great idea in New Zealand and probably if you are a ski bunny in Aussie. You guys will well know what temperatures we have here in NZ from your experience 2 years ago. And you will also know the issues lithium has charging at below zero temperatures and potentially the damage that can occur to the battery. The battery location is very much a horses for courses situation.
For sure! I can understand that! I like to think I’m well versed to give advice for Australian conditions but I am definitely not scared to say I have no idea about NZ
@@SarahandKeelanTravelsfor cold temperatures, you can get batteries with internal heating elements in LFP and NCA chemistries - we've been using them in 24V applications for ages.
SKT. Thanks for another amazing educational video. Love learning from those who know 1st hand about the matter not just spouting nonsense
They are broadly Lithium Ion batteries the key two are Lithium-Ion - NMC (Nickel Manganese Cobalt - Older slightly more energy dense) and Lithium-Ion - LFP - Lithium Iron Phosphate. Both emit noxious fumes and if they happen to go into thermal runaway will still self-propagate. The chemistry change was primarily driven by the cost of Nikel and Cobalt as the NMC are more energy-dense.
Perfect logical explanation Keelan. Thanks. Same advice applies if using AGM re overcoming voltage drop. Battery near charging gear.
i am in the process of building a camp trailer and this information came at the right time before i started on the electrical system.
SKT - Love these 12v vids Keelan, your adhd has really helped me learn so much more about it! Cheers mate
Im glad i sourced all my materials for the installer to use. They wanted to use 8g wire to go from my engine bay to my boot in my 80 series. Admittedly 4/0 was and is overkill but voltage drop is bad. And i like headroom.
As always enjoying your videos, I like that you give a lot of info and point us in the right direction, SKT you guys are the best :)
Great information Keelan
I’m upgrading my caravan to lithium
Skt icheck products seem like the go would love to try them 🎉
Great info. Thanks heaps. Love your work.
SKT. Thanx so much Keelan for great information. So helpful for people like us looking to get first bank. The future
SKT Thank you so much for the simple layman's explanation. Almost got all of your explanation .. placement of battery's and chargers .. under the bed .. vented .. but not sealed air tight!! Just got to work that out. Thank you again 😂
I upgraded my lithium battery to a larger size back in July 2023 in anticipation of the new 3001 rulings. During the upgrade that included a new BCDC I noticed the builder of my caravan Nov 2021 caravan didn’t fuse the solar panels at all!
As an electrician I found this unbelievable. The other thing I noticed was the size of fuses used for all the circuits. Everything was fused with 20Amps. I’ve since rationalised and put the correct fusing in to suit the cable size.
SKT great info just getting our caravan built will call now and check where the battery system is going to be Thanks 👏
Thanks SKT for always putting out quality no BS footage and advice, love watching your videos and learning at the same time.
Thank you Keelan that's awesome and really clear. Keep building on this information, given your experience any nuggets you can give us would be awesome, even consider a bit of an electrical series when you're not out and about, something you can do when your not camping. Anyway thankyou 👍👍
Great advice for a novice like me!! Love your work! Thanks heaps SKT
13:20 where charging equipment is a long way away from the batteries, makes me think are there units (or mods) where you have a battery voltage sense cable running from the charging unit to the batteries. This way battery charging voltage is measured directly at the battery, and the drop across the charging cable will be compensated for.
Well done!!!!! Finally a youtuber that is ' allowed', ' qualified' to speak about a topic. Firk yeah, good on ya.
Mate … I’ve been critical of a previous vid on this topic you posted as I too am very passionate about 12v / solar etc systems and powering off grid van life AND GETTING IT RIGHT, so I am very happy to agree with everything you stated on this one mate. SKT nailed the topic and the presentation. Great work and keep it up bud!
Very interesting, didn’t know about the difference in the Lithium Phosphate , Lithium Cobalt Batteries. Individually fused is logical for the panels too for fault finding and voltage drop. The isolator is logical too. Many systems have a Mains inverter which has power constantly and having mains always available on the wiring even when the 15A connection is removed is dangerous if you forget. Nearly lost a friend because he cut wiring accidentally on a UPS. Volt drop at 12 Volts is commonly misunderstood. Thank you for your video.
SKT thoroughly enjoy watching y’all… so much knowledge shares and amazing places…. Makes us happier than a dog with two tails. 🐕
“The experts” wired up 12volt side of my absorption fridge with 1.8 mm2 wire. It had voltage drop of 2.4v from the car battery. I put in 10 mm2, now it works.
Thanks for going thru the new requirements Keelan. Most impressed. I will be doing the Itech EOFY sales and will be taking up the SKT advantage.❤
SKT a great video to help people understand the new laws and to save people money, i am still yet to have my complete itech 480ah lithium caravan kit installed so this video will be a great help when planning where everything goes. Cheers mate.
Alot of info and great tips, love you put it into terms that everyone can understand well done SKT
