I would not consider this a failure, the battery performed great. Good advice to check the temperature of the terminals when charging and using it and I will be doing so. Just bought a 100ah slimline lithium from kings for my off grid camper build, thinking of getting a second one if I can fit it into the build. I will be charging it up in the next few days. If terminals run hot like yours did I will be exchanging it for another one.
I'd also like to know how you went. Don't forget to run batteries in series or parallel they should be from the same batch of manufacture - check the serial numbers
Thanks Craig, I always enjoy your videos. I have 2 x 120amp king lithiums in parallel and so far so good. I will actually check the temperature of the terminals when under load now to see if I have a similar problem. I did notice while charging it once the terminal did get hot. I thought it was because the charger wasn’t attached good. Might need more investigating. Thanks for the vid.
Good review my arse. He put 120 amps through his battery, you gotta be nuts the limit is 50 amps, he wonders why the terminal was red hot. He's completely clueless. The BMS on that particular battery is limited to 50 amps. Your never supposed to put more than 30 amps through a lithuim ion phosphate RV battery. This is exactly why you never ever connect a lithium ion battery to a car alternator it's a big no no because of the 80-140 amp current produced by a car alternator. Those batteries are designed for PV discarges of between 15-40 amps max
@@Peter-b6e3x BS! Here is the spec: LiFePO4 QUALITY BATTERY MANAGEMENT SYSTEM (BMS) Inside the battery, there’s a quality Battery Management System (BMS) that ensures safe and reliable operation. The BMS intelligently monitors each individual cell and balances their use to ensure your battery is charging and discharging evenly. It will also disconnect the battery to prevent damage from high or low temperatures, high or low voltage, overload and even short circuits. The quality BMS in this Adventure Kings 200Ah lithium battery is rated to output a continuous 200 amps, meaning you can easily connect and power any Kings inverter to run any 240V gear without a worry in the world!
@@Peter-b6e3x the battery in the video has "Max Continuous Discharge 200A" printed on the side of it & the specifications on the website say the same thing. Where did this 50 amp limitation come from?
I wouldn’t say that terminal was loose enough to cause any issues, it’s also very inconclusive as we couldn’t see the top side as it was moving. I’ve watched it many times zoomed in at .25x speed and at 22:07 the hex nut was 100% moving with the lug which means the entire connection is moving through the casing, which also means perhaps it was over torqued. If it was actually a loose connection it would be moving easier than that. These are still very good value lithium batteries.
Good job Craig. I have 3 of the Kings 200A lithiums, a black top (older model) & 2 x blue tops, I’ll have to do a heat & performance test after seeing this. From what I have seen in reviews the Kings batteries are actually fairly decent by most standards, even the higher end batteries are not entirely devoid of this type of processing faults and many (most) over rate their capacities anyhow. This was a good spot & an obvious red flag people need to look out for when buying & installing a lithium battery setup. TFS. Cheers
At such a high continuous discharge rate of course the battery won’t give you the full 200ah. Tests should be done at 10a discharge and then it will probably give you more than 200ah.
Thank you for sharing this battery test as I was about to buy one myself. I for one really appreciated the longer video since I was really interested in seeing the whole process of testing. Well done 👍 You definitely caught my attention seeing your setup for testing and will continue watching now other videos you made and can hopefully learn from your knowledge and experience 👏👏 Cheers Jim
The AH rating of a battery is done with a .2 c discharge rate. 40 amps The fact you got almost the batteries rated AH under a high load like that shows that those are very good cells.

This makes we wonder do other Lithium and or AGM batteries have the same issue. It is certainly food for thought and thanks for exposing an issue that most do not know about.
Good video , I just brought one of these batteries but I am not keen on dissembling due to warranty considerations but will test the heat when I discharge it and set it up for a dc to dc car charge 40amp redarc and hope it doesn’t heat to much .
Like ya channel and style straight up down how it is Aussie style no bullshit just how it is well done thankyou for your time you save us all out here alota f.cking around .
For longterm storage run the generator out of fuel and just either buy fuel when you need the generator or make sure you turn over your petrol using other products. The aging of fuel is more critical in small quantities ie. inside the carburettor. For medium term storage you could turn off the fuel with fuel in the tank and then run out the fuel in the carburettor.
At such a high continuous discharge rate of course the battery won’t give you the full 200ah. Tests should be done at 10a discharge and then it will probably give you more than 200ah. This battery did really well.
Great review. I agree this is work in progress. The internal termination to the output terminals is a bodge! What about vibration on a corrugated road/ moisture etc great for 12 months, what is the waranty period?
Since you’ve pulled it apart…..have you checked to see how closely the cells are balanced….? If one is out of balance……that may be enough to affect the total output…….
I am no sparky, but how thick is the square lug/amp rating of this lug connected directly to the +ve terminal? Could this be the potential hot spot if it is too thin and wouldn’t that increased resistance increase the temp at the +ve terminal? It might be the camera angle, but the bus bar on the -ve terminal looks a lot thicker.
Its actually a fuse and will get hot. That is where I suspect the heat is building up not the loose connection. The fuse seems to be missing after the internals are remove from the box but could be wrong. I have been looking at videos all day. I just bought 2x 200ah Queens on ebay for $899. I cant find anything about them hope they are good.
@@sparkletornado5890. I retested with the terminal fuse both on and off and it really made no difference to temperature. It was the loose terminal that created the issue. If I get a chance I’ll do it on camera and upload the footage.
Thanks for checking. At 158amps you only need 0.0064ohms to produce 160w. You can use the Kelvin measurement to check very low resistance. I got my Queens batteries today. They look good I did not get the kings after this video and another teardown video. Do you buy them to test? The queens is $449 online free shipping atm. @@craigsolaradventures
If you tighten the loose terminal would the temperature drop? Love to see it if you haven’t destroyed the battery. My boy is looking to get in camping and doesn’t want to spend a lot of money. Kings products seems to be a good starters pack to see if he enjoys it.
Yes the temperature would normalise if the terminal was tightened. However as the terminal in question was inside the battery you have no way of doing it without removing the lid. This obviously voids warranty and the average person would not normally check this of even know they had a problem that potentially could cause a fire.
Craig is right of course, tightening the terminals would normalise operation & it should run cooler. While this could be a concern with ANY lithium battery, now you know how to check for such a potential issue by testing the battery under a decent load and stress test all your connections before putting a system into service. I have a fair bit of Kings gear myself, I have to say for the price point, it is pretty hard to beat, and the batteries and inverters are probably the best value you will find, there are a lot of name brand batteries & inverters that aren’t as good and cost 3 times what Kings charge. I think Kings products would be a perfect way for ur young fella to get into the camping scene, if people looked after their gear better it would last longer & Kings gear is no exception, I have seen guy’s that have had a Kings side awning for over 3 years without issue, while many others complain they are rubbish, it all comes down to how you look after ur gear & if it is a bit cheapish & substandard, then take more care of it. Hope he has a ball with it.
@@MikesManCave That is correct, and he also shows the temp on the negative terminal which did not get hot because it did not have a loose connection like the one on the positive terminal.
You've probably just over torqued the positive terminal! If you start spinning the threaded plug it will loosen the inside terminal. There is a recommended torque spec for 8 mm terminals. A lot of VIP BMS have Bluetooth, would have been interesting to see if there was an unused port!
Just wondering if you contacted Kings or 4WD Supercentre regarding this loose terminal? If it causes heat and possible fire risk and is common issue then they should be made aware of it. Thanks for the review.
I did go into the shop in Canberra when I was passing through and mentioned it to the sales team, they said it would be followed up. Never heard back from them.
in a competive world i would buy the battery that goes over it's rating and a lot do . lets say by 3% and this one is about 3% under making a difference of 6%
These are the tests we all want to see on all batteries. The manufacturers should be doing these videos. Not RUclipsrs. Great work! Would you recommend going with a single 200Ah or two 100Ah?
Most Chinese lithium ion batteries have only 55-60 % of their stated amp hour reserve. I wouldn't buy simply because they are only 50 Amp BMS, bear in mind the last 10 amps cannot be utilised due to the voltage dropping to under 11 volts which won't run even a 12 volt fridge

It’s a shame that a loose terminal failed it but that is a worry Unfortunately I have seen two of the king’s battery boxes melt in the lid for the exact same thing Under the internal lid loose terminations on the cables
For the price I and a lot of other people wouldn't call this a "failure" surprised the heck out of me. For a easy fix loose terminal I'd save atleast half my money..
The capacity is probably there. Heaps of heat loss with the high current draw. Losts of glue, huge case, blocks on top with glue. It's a bit like buying a second hand car with a new paint job. You don't get to see what's under the paint. Better to buy the cells and a better BMS and put it together yourself. Much cheaper or much bigger capacity.
just out of interest .... would you have lost those amp hours due to the bad terminal and how many hours did it take to run out with the heater on drawing what was it 1500 watts i live in the UK and these batteries are expensive thank you in advance if you answer
Thanks for the review mate and good pick up on the lose terminal, a few might think nothing of this but over time that could be the difference between a great holiday and all your gear burnt to the ground.

Hi Craig , looks like i had the same problem with hot terminals. My auto elec tested mine by running the air con in my caravan and had no problems. I then went away with the van and the first time that i used it one of my Kings 200amp batteries went up in flames straight away. Kings have just basically sent me away as they don't want to know about it. They also refused to give me a written report. Buyer beware with this product Also Kings service was nothing less than terrible , 6 visits over 4 weeks and not even one phone call
What battery or batteries do you use mate you cut that short like have you ever used them if you going to have a opinion give a reason mate not rocket science.
Wouldn't expect anything else from KINGS. How's the old saying go? You get what you pay for. I know a lot of people won't think much of the temperature on the terminal but that is what will cause a failure eventually with a possible fire.
Loose terminals and high current = arching / heat, end result is fire, that's a very poorly built unit what do you expect for $699, poor QA / design Made in China Rubbish, do yourself a favour for peace of mind don't buy this rubbish, take a look at the Renogy 200A, Build quality is excellent 5 year warranty and $1199, if Kings didn't glue shut the box you could easily check for loose terminal, because they glue it and if you pry it open you void warranty, absolute garbage, I hope Kings see this review to see how crap their products are inside.
shocking people think that is a good battery, for not much more you can get a far better battery than kings. and yes Renogy core is a good option, and Renogy have been making Lithium batteries for for over a decade. you can open the renogy core battery up, its got a dedicated frame inside to hold the cells in, not bad sika knock off glue like that kings
@@oliviatulloch1358 Yep, I have some Renogy stuff and it's been fantastic, the quality is exceptional, after sales service has been 100%, not for faulty stuff as nothing's gone faulty, just for wrong order, they were onto it instantly, and had it returned, refunded and replaced in a matter of days, WillProwse test heaps of Batteries / Solar etc, he rates the Renogy as good gear, other batteries to consider are Aussie Batteries
I have only had one experience with KINGS and it was my last, they failed in every aspect of business, from product through to customer service and everywhere in between, NEVER AGAIN.

6. Most Lipo4 batteries come from China, & yes many make false claims & are crap, but many are not.
7. I have 3 Kings 200A lithiums & all seem to be fine so far, 1 black top & 2 x blue top.
8. I agree they are an A grade option for the price point.
Loose connection means increased resistance...hence higher temperature.
the victron is nice but you can buy 3 of those kings ones for the same price
It’s a shame that a loose terminal failed it but that is a worry
Unfortunately I have seen two of the king’s battery boxes melt in the lid for the exact same thing
Under the internal lid loose terminations on the cables
For the price I and a lot of other people wouldn't call this a "failure" surprised the heck out of me. For a easy fix loose terminal I'd save atleast half my money..
dam good battery
Yeah, the only thing I agree on with this being a failure relates to that loose positive terminal.
I don’t think Kings use A Grade cells due to the low cycles whereas an A grade cell would give you upto 6000 cycles
The capacity is probably there. Heaps of heat loss with the high current draw. Losts of glue, huge case, blocks on top with glue. It's a bit like buying a second hand car with a new paint job. You don't get to see what's under the paint. Better to buy the cells and a better BMS and put it together yourself. Much cheaper or much bigger capacity.
just out of interest .... would you have lost those amp hours due to the bad terminal and how many hours did it take to run out with the heater on drawing what was it 1500 watts i live in the UK and these batteries are expensive
thank you in advance if you answer
Anyone done an itechworld teardown??
Camping has become a game of over complicating everything. Relax.
Is this your job or a hobby
Victron battery has no bms inside so can be smaller.
Thanks for the review mate and good pick up on the lose terminal, a few might think nothing of this but over time that could be the difference between a great holiday and all your gear burnt to the ground.
Instead of a thermal spot instrument, far better with a thermal camera.
Agree totally, but I don’t have one so I’m working with what I can.
Well made batteries are usually a couple of percent over their rating when new. 98 percent is not good.
There is no reason at all for a 12v disconnect
Gee what a shocker you've been discharging at 131 amps for hours and the terminal is a little hot. Really!
I have this battery in my Avan now for 6 months
It has never gotten below 12 volts running my fridge 24-7
On solar and while in the bush for two months gold detecting
Never flat not even below 12 volt
That’s TV lights fridge battery charging my gear too
Had no problems with it lipo4 only
Have the 130 in my truck running my other fridge 24-7 never below 12
CANOT say anything bad about them
The missing A/H was in the hot battery terminal
Hi Craig , looks like i had the same problem with hot terminals.
My auto elec tested mine by running the air con in my caravan and had no problems.
I then went away with the van and the first time that i used it one of my Kings 200amp batteries went up in flames straight away.
Kings have just basically sent me away as they don't want to know about it.
They also refused to give me a written report.
Buyer beware with this product
Also Kings service was nothing less than terrible , 6 visits over 4 weeks and not even one phone call
Does better than 2k DCS battery
kings control product, MUST GAME UP!!!! IT IS SHOCKING HOW PEOPLE IN CONTROL ROOM OF PRODUCT DO NOTHING!!! SHAME,
Wire size 2 gauge but better bigger size
You couldn't give me a Kings battery.
What battery or batteries do you use mate you cut that short like have you ever used them if you going to have a opinion give a reason mate not rocket science.
What would you suggest apart from kings
Well, they can't call it 200 if it's not 200
The barcodes are rubbed off the cells on Kings batteries, which means they are made with second hand repurposed EV cells
The cells are most likely BYD 3.2v "100Ah" LFP that failed their QC @66Ah but I maybe wrong.
Never drain battery below 10 volts ..
Wouldn't expect anything else from KINGS.
How's the old saying go?
You get what you pay for.
I know a lot of people won't think much of the temperature on the terminal but that is what will cause a failure eventually with a possible fire.
Loose terminals and high current = arching / heat, end result is fire, that's a very poorly built unit what do you expect for $699, poor QA / design Made in China Rubbish, do yourself a favour for peace of mind don't buy this rubbish, take a look at the Renogy 200A, Build quality is excellent 5 year warranty and $1199, if Kings didn't glue shut the box you could easily check for loose terminal, because they glue it and if you pry it open you void warranty, absolute garbage, I hope Kings see this review to see how crap their products are inside.
Thank you ! Couldn’t agree more. Not everyone gets it.
shocking people think that is a good battery, for not much more you can get a far better battery than kings. and yes Renogy core is a good option, and Renogy have been making Lithium batteries for for over a decade. you can open the renogy core battery up, its got a dedicated frame inside to hold the cells in, not bad sika knock off glue like that kings
@@oliviatulloch1358 Yep, I have some Renogy stuff and it's been fantastic, the quality is exceptional, after sales service has been 100%, not for faulty stuff as nothing's gone faulty, just for wrong order, they were onto it instantly, and had it returned, refunded and replaced in a matter of days, WillProwse test heaps of Batteries / Solar etc, he rates the Renogy as good gear, other batteries to consider are Aussie Batteries
It’s a fire hazard
I have only had one experience with KINGS and it was my last, they failed in every aspect of business, from product through to customer service and everywhere in between, NEVER AGAIN.
A waste of space, maybe t he space is for heat dissapation
Hmmm yet you could of over screwed it from the start. Ive done the exact same test with Kings, no issues. Im running 4 Liths now in the utem 2 in van. Going strong
You burn battery . Temperature to high 50 C max exceeds that temperature… amps high long time ..bad test
No worse than the big brands
Why would you be suprised???? You’re pulling 140amp out of a 200amp battery!! Who in there right mind would EVER need to pull that much power in an hour and a half! Really dumb misleading vid
The battery is rated at 1C.
Quote from Kings “The quality BMS in this Adventure Kings 200ah lithium battery is rated to a continuous 200amp, meaning you can easily connect and power any Kings inverter to run any 240V gear without a worry in the world!”
Really dumb … in your opinion, misleading absolutely NOT !.
You dont put 120 amps current through a lithuim ion phosphate RV battery. You are completely clueless! 76 C = sky high amps current .
lol its not a Lithium Ion battery, its a Lifepo4 (Lithium Iron Phosphate), If it was a good battery it would take its rating of 200amps easy enough.
LOL!
Here is the spec: LiFePO4
QUALITY BATTERY MANAGEMENT SYSTEM (BMS)
Inside the battery, there’s a quality Battery Management System (BMS) that ensures safe and reliable operation. The BMS intelligently monitors each individual cell and balances their use to ensure your battery is charging and discharging evenly. It will also disconnect the battery to prevent damage from high or low temperatures, high or low voltage, overload and even short circuits.
The quality BMS in this Adventure Kings 200Ah lithium battery is rated to output a continuous 200 amps, meaning you can easily connect and power any Kings inverter to run any 240V gear without a worry in the world!
Stupid asking a battery to discharge 200ah
Why ? If that’s the rated spec 🤔
that is an ugly battery,, no way these would make it into our company builds. In this day an age, for not much more you can get far better batteries, that dont look that nasty in side, that BMS is so cheap
what is your number for "not much more" lol there is no battery close to that price for that Ah. Stop talking out of your ass
