1yr of torture… Heat, corrugations, water crossings and 40,000kms around Australia. Has the iTech120X PRO held up!?
Nothing has changed, I’m still told time and time again that my lithium battery won’t work, it's not designed for under bonnet applications and I’m wasting my time. But time and time again I’m still here reviewing these units.
I’m not out here to try and advertise lithium (whatever the brand) or to try and convince myself that it works. I’ve been given the opportunity to test these packs to within an inch of their life so why not? Why not see exactly what these units are capable of and just how far they will go.
In this episode I cover all of the frequently asked questions in regards to my 120X PRO lithium battery and of course we cover that famous capacity test and compare it directly back to the results of the brand new battery and 6 month old battery.

Nathan, I'm a 60yo that has spent my life working and associating with stacks of Aussie apex smart ar#es that know everything and truly believe they were put on this earth to tune everybody in as to how things really are... Mate!, you're never going to change what they think. Don't even respond. Just keep doing what you are doing. People with any kind of mature IQ can sort the bullsh#t reviewers out from the good ones. Stop justifying yourself. You have informed us all when you need to show transparency, that should be enough. 👍👏 JT from Kalamunda.

I’ve had itechworld batteries for years. The one under the bonnet of my 100 series is about four years old now. Never did a capacity test but it has never given cause to need one. The Cruiser tows a caravan and the battery has been underwater too. The other three are under the bed in the van. They are doing what they are supposed to as well. Great review Nathan 😅

@auroracreative3544 4 месяца назад

Thanks for the honest review. I had an Itech World 120ah battery, underbonnet, in my LC200. It shut down on me twice late in the afternoon when drving in 40 degree plus heat in QLD for over 8 hours at a time. Similar to as you described. It did come back later in the evening. Initially it was concerning, so I swapped that out and put that battery as a back-up in a Projecta PowerHUB. I now use the 120X PRO in the LC200, underbonnet, and heat shielded it in CarBuilders Heat Shield, much better material. We did the same drive and after another 12 months we haven't had an issue, so I do believe it is in the heat shielding and the ventilation of the engine bay at the end of a long hot drive.

Nath, fantastic review as usual. Very well structured, informative, accurate, fair and honest. You are one of the best at reviews. That’s for sure. As for the battery shutdown issue as others have mentioned, I feel it is delayed post heat peak because of the insulation you have placed on the battery. It will delay heat buildup but once heat soaked will take longer for the heat to dissipate and hence the BMS shutdown occurs a few hours post engine bay heat peak but coincides with battery and BMS peak internal temps. Would be good to test with and without insulation to see if there is a difference in shutdown times.

@AussieAdventurer 11 часов назад

Good video and fair impartial review mate- thank you and keep it up 👏 Curious if you could do a review on the new iTECH400X PRO- that one interests me personally for use in my old Caravan as a drop in replacement unit. I understand that the one you reviewed is also a drop in replacement battery for older systems not designed for Lithium- I wonder what your thoughts are about using them as a drop in replacement and what you would thing WE need to do to keep them maintained - A new lithium Chager or just stick with what we have in our old caravan which is only designed for AGM battery charging ????Hmmm I wonder 🤔 Cheers for the info and effort you put into this test.

@Alan.livingston 4 месяца назад

I’m sure someone has already said this, but the heat issue is probably heatsoak. When you are driving you probably have some sort of airflow through the engine bay but once you stop the battery is sitting next to that big old hot engine and nowhere for that heat to go. It’s probably a gump idea, but maybe you could put a 12v fan in the bay when you stop on those extreme days to move the air around.

@davewarland1680 4 месяца назад

Great honest and informative review as always. My DCS under bonnet setup is a touch under 5 years old and still going strong, yes it has lost some capacity but still far in front of any previous lead battery setup i have used and none of these would have lasted 5 years. When this setup dies i will only go lithium again as i believe its worth it and really dont care what anyone else thinks about it.

And it's interesting he's now going all out with some hideously expensive import lithium units, obviously the most brilliant thing since sliced bread, just as the DCS were in the early days of his reviews. He simply can't be persuaded to try Aussie designed Itech products neither. According to him, too many negative results, Nathans reviews won't even persuade him. Oh well, it's His choice.

@Crankycruiser Месяц назад

My itech 120x pro died underbonnet in the middle of a cape trip right when i needed it. Im certain heat caused it. It shut down mod morning and did not come back to life until ar least 9pm. Problem was it had massively reduced capacity. It only last a couple of hours then shut off due to voltage. It did this every day whilst on the trip. Itech did warrant it, but i didn't bother putting it back under Bonnet.

Nice Nathan, genuine use and testing. It's interesting what's unfolded over the last 6-12 months with more and more tests and examples of failures of the much more expensive DSC under bonnet batteries (a mate tested his at 17 & 22% loss over 18 months). My guess is the same haters are now a little butt hurt 🤪Realistically all brands are going to have the odd bad one.... The value per amp for these is fantastic and the degradation under bonnet is very acceptable.

@TheJanope13 4 месяца назад

hey mate if you forsee yourself fully draining the battery till BMS cut out, you should put a momentary push button switch from the starter/alternator in feed to the battery output . saves you pulling out the jump pack every time you need to do it :)

@LockyourHubs4WDing 4 месяца назад

Sounds like heat soak with the cut off issue. Does the Redarc have a power supply mode? I use that feature with the Victron DCDC to "Jump Start" shut down lithiums. EV manufacturers implement an active heating/cooling system in their battery packs, it would be great to see something similar designed into an aftermarket house lithium iron battery. It would be interesting to see long term datalogging of the battery's temperature , under the bonnet.

@explorewa4wdadventures808 4 месяца назад

Hey bloke! Great video. Im suprised by your results. Not my experience with lithium underbonnet. I think its a rather good look for the itechx. Most BMS shutdowns seem to be around 80 degrees. I agree though; i saw some unusual timings on BMS shut-downs & i think it had to be thermal heat soak. Great vid again.

@jebw 4 месяца назад

Great wrap up on your lithium expirence. Thermal enersia is what I think you expirenced with the late afternoon battery shut down. . I've had issues with besser block equipment sheds reaching maximum internal temperatures about 8 hours after the external maximum daily temperature. Initially it was hard to believe until we did temperature logging.

@XploringOz 4 месяца назад

Yes, I'm thinking this was the case, overall very impressed with how it performed in the grand scheme of things 👍 Might need to start temp logging

@philg2468 4 месяца назад

Perhaps you could measure the temps around the battery? I expect the hottest time is well after the vehicle has stopped and there is no air flow. In addition, while your insulation might slow heat getting in, it will also slow the heat getting out. I'd be using a shield (similar to what Toyota fitted on the 80series) rather than wrapping it in insulation. Good thorough battery test - great work!!

@leblancexplores Месяц назад

Open it uppppp please… it’s not the heat man, its contents will let us know why these will hold up, understanding the mosfet configuration and if they are using super caps is the only way to know if their “battery tech” is running within specs of the chemistry. From what I’m reading the specs seem pretty “off the shelf” for a standard BMS with the short circuit protection delay set high.

@AussieDazza 4 месяца назад

Great results but it is a surprise considering scientific tested says that Lithium ion battery optimal operation range when charging is between -20 to 60 C . Battery degradation happens outside of those temperatures. Maybe your protective insulation on the sides keeps it for the most part under 60 C.

@XploringOz 4 месяца назад

For sure, I understand the the lithium chemistry may suffer at those ends of the optimal use range, however so far so good. I'd expect the majority of the time I'd be running within those parameters. 👍

@pommy5094 4 месяца назад

Hey Mate Can i ask what you are using for your cranking battery and how you configure your 12v accessories under the bonnet. Just bought a lc200 and my wiring even though clean, doesn't seem correct. It would be awesome to understand yours

@ianweal3081 4 месяца назад

Hi mate, just as a majority suggest here, it's a heat soak issue due to zero air circulation once idle. I think that's the issue. Im absolutely amazed you didn't think to produce you thermo gun at the time and get an internal temp, you must have been heat affected yourself 🥵🥵🥵🥵. Beer o'clock time. I'm having an issue with my BCDC under bonnet location, its reaches temp and shuts down, bit of a downer as it stops any solar input also. I installed a fan as suggested here but alas it just stirs the hot underbonnet air, so not rectified. Hence I'm in the process of relocating the BCDC to better air circulation. As always, regards Wealie.

@XploringOz 4 месяца назад

Yes, it must be the heat soak issues, however I don't think its in relation to slow speeds as the drive I did on the 4th occasion was all sealed highway driving (without the trailer) and it had plenty of airflow. It must just be that long exposure to the constant heat that just builds up slowly over the day 🤔 I did get the thermo gun out once, but it's very hard to measure around the hot engine with the extreme temps from there and it really only measure the external casing temperature which is significantly different on the top cap (uncovered) to the side panels. 🥵 Yes, the BCDC chargers suffer from the same issue. I've not had any issues with my one installed up front in front the radiator at this stage 🤞 Cheers

@petergair4726 4 месяца назад

Nathan, once again, great job, thanks! I’ve asked this before and you didn’t answer me for whatever reason but I’ll try again & we’ll see if I get a better result. You were running the ITechworld’s starting battery at one stage and you were having trouble with it levelling with your auxiliary battery so you pulled it out, did you ever sort that issue and put it back in? If not, why not and if so, what are the results with it?

@ianweal3081 4 месяца назад

Hi Peter, I'll let Nathan explain his outcome but I can answer this from my prospective. The 1420CA-Pro (Itech cranking battery) has to seperate from any auxiliary house battery just as all other cranking batteries require, hence we utilise voltage sensitive seperation devices. The issue is: Redarc BCDC units, battery isolators etc. usually seperate at 12.7volts. That voltage leaves the lithium cranking battery voltage too low for reliable starting, exactly as Nathan experienced. I was fortunate, Itech explained that issue to me when purchasing mine. The recommendation is a programmable Victron unit allowing you to set a higher seperation voltage. Myself, I didn't wish to go down that avenue as it's just another fancy piece of tech to learn about that may well fail. My answer was a simple one. I once utilised a Redarc SBI12, it's a voltage sensitive relay. I replaced that with the Redarc BCDC25D. The Redarc SBI12 is just a relay with voltage sensitive circuit bolted on. I removed the voltage sensitive circuit, connected the relay activation coil directly to ignition wire (wiper motor in GU Patrol), hence ignition on, relay activated, ignition off relay open. You now take you cranking battery positive to the relay, then onto your normal DCDC charger, thus you auxiliary house battery gets supply whilst ignition on hence alternator charging both batteries. Ignition off, batteries immediately seperate, auxiliary/house battery only draw down, the 1420CA-Pro stays at peak cranking voltage. Be aware, your DCDC charger still provides any solar panel voltage to auxiliary/house battery/s. My Itech 1420CA-Pro was installed 5/5/22. 22 months of great reliable starting ompth. I happy with my choice and am happy to recommend to anyone considering one.

@petergair4726 4 месяца назад

@@ianweal3081 I’ve got the cranking lithium fitted to my lc200 as well and also very happy, I’ve just held off with putting another lithium under the hood because of what happened with Nathan. Thanks for your explanation, it helps to know what actually needs doing.

@ianweal3081 4 месяца назад

Glad to hear your impressed with 1420CA Pro as well. I think you'll find Nathan is running both Itechs, 1420CA Pro and 120X Pro under bonnet, exactly as you wish to. In my GU Patrol I elected to run my auxiliary batteries (3 X Itech 54amp = 162amp) in the rear, as the space allocated under bonnet is directly beside Turbo, far too hot for any battery in my opinion. At least yours are up front in ambient air flow. Hope you get your reply. I actually though he covered this in another video but my ay be totally wrong. Regards

@gavinwilliamson3944 4 месяца назад

Hi Nathan, This appears to typical for the battery's I've tested. Installed in 4WD and campers. Brand on the battery does not really matter. Unless its a eBay special..... Sigh.(Some are OK. maybe) The ones that seem to degrade the least. Are ones installed in vehicles that are charged 100% daily. With light loads. Eg 1 fridge and some lights ect. Campers seem degrade more. I have not been able to pin down why? The degrading is less with age. Year on year. As this technology is fairly new to be popularised. It is hard to get 12V battery's that are over 5 years old for testing! Unless I get old Telstra cells. Quality lithium's probably will still be going strong in 10 years. Maybe at 75-80% of original capacity. But that's no reason to bin them. You would be on your third set of AGM's by then, and still have more usable capacity. I believe the iTech products are the same as a popular Chinese brand. Sold in the USA and Europe. (you cannot buy it here) But in saying this. There has been NO compromise on quality on their battery's. Value wise, they could knock a couple of hundred $ off. When compared to the other brand. But you get local support and warranty services. So there are really no complaints.

@Ask_Harry 4 месяца назад

is it isolated from your cranking battery? How does this work?

@krismezza 4 месяца назад

It'll be isolated from the crank, connected to the BCDC which is connected to both. Once the BCDC sees the crank battery is fully charged, it will begin sending charge from the alternator to the lithium aux battery. Because the BCDC acts as an isolator, when you drain down the aux battery, it wont let any charge from the crank battery power devices connected to the aux battery, so you will always be able to start your car

After a career in the battery industry spanning 18 years I can tell you that your test was flawed in so many ways that make your results totally disconnected from the battery capacity specification. The only valid information you presented was the comparison between each test as long as the conditions were the same. I can't understand why you didn't research the correct method to capacity test a battery, the information is widely available.
