Hi Glen We appreciate your videos, I've just watched king's latest video on there batteries and left a message for them to watch your videos, hope they help and help there manufacturing with there quality control ✌🏼
I have sent an email to Kings with some photos and they have gotten back to me thanking me for letting them know of the issues with this battery. They are going to pass it on to their products team for a further look.
regarding the strapping / damaged cells, perhaps the cells have puffed since fabrication. at the time of assembly, that tape may have been perfect? just a thought.
Kings gear is ok and their support is top notch. I think they realise their manufacturing teams may not be 100% quality but they always seem happy to exchange so for ppl working on smaller budgets i reckon kings is great. They can sponsor my channel anytime 😂
Yes I can't fault their customer service. Around 5 years ago I had a generator fail with under 20 hours of use and Kings were top notch with their return / refund process. I am going to do some tests on this battery, gather some results and contact Kings with my finding so it can better help with their product quality control.
Not bad - the strapping could be improved to reduce stress on the cell, but the thermistor isn’t really an issue - bonding to the cell make stuff all difference.
@@TheSimpleLivingAussie Definitely better fixed to the cells. An airgap gives incorrect readings. Thermal glue should be used so the sensor is reading accurately
Bwahaha what are comments deffending this sub par battery... very swollen cells build quality that seriosly damadged said grade f cells, wire management that is not only sloppy but a few balance leads touching the razor sharp +/- buss bars that vibrate with movement and the sharp edges will eventually cut into leads in a mobile application. WOW the only plus i see is the tiny vip bms which has proven itself in much more capable batteries! These batts should cost well under $100.
Lovely ep and tear down of the kings 60amp, How good is the timing of this I was looking at buying one of theses 60 amp batteries for my 3,7m tinny to run my GPS combo thanks for sharing, will wait and see wait you think of it,
Finally got to do the most important test of all with one of my 60Ah Kings. I used a 12V Rovin kettle to boil water for a mug of coffee. Used about 45Wh in 20min to bring it to 85degC where it cutoff. Passed with flying colours. Going to replace the cig plug with mini Anderson 30A connecters (or Powerpole if you can't find them) to reduce voltage drop but otherwise the battery is excellent value for small lightweight jobs.
I do love this little battery for size so be interesting on the capacity test results I get. Either way I am still going to use the battery, be great to see how damaged cells preform longer term.
Geez us ,I took delivery of the same battery last week to run my small electric Water Snake trolling motor and for overnight camping trips for my Kings 20 L Escape fridge . It ran the fridge for 30 hours at 28 C ambient temp , but to be fair when the fridge got to the set temp 1 C I filled the fridge up with room temp cans of beer and other stuff . It took nearly 5 hours to get back down to 1C with the compressor running all the time for that period , so to be fair, it probably would have run a lot longer if the beer had been cold when placed in the fridge . I was going to buy another one of these batteries but thin I will wait until I see your next video , especially the response from Kings . As an aside I also purchased a I-tech Life PO4 50 S to be be set up inside my vehicle with a 25 A DC - DC charger . Upon hooking up the itech to said fridge with every thing cold ,it has been running for 19 hours and is already down to 13.01 V . Battery was charged to 13.45 V before use ,but went down to under 13.2 V in 3 hours ,doesn’t seem right to me . Thank for listening 👍
Going to do a capacity test today and see what it comes back at. I will be running this battery, testing it and seeing how it preforms with damaged cells, over a time period. So in a way, it's kinda good I did get a dud as it gives me the opportunity to see how damaged cells preform over time. I also do plan to test some iTechworld batteries in the future.
Calculating remaining battery capacity using Volts is flawed - you should be running through a shunt if you are really interested in capacity used/remaining.
@@einfelder8262 Thanks for the information . According to my chart 13.4 V is % 90 capacity 13.5 is % 99 capacity . I changed over to the I tech battery when the voltage went down to 12.8 V or 20% according to the chart . All readings were done by a Kick Ass constant battery monitor and also checked by 2 seperate multi meters which were very close to each other in the readings . Any information you can give me will be greatly appreciated. Both batteries are brand new . Cheers
@@reddyman6915@einfelder8262 is correct, you need a shunt for lithium batteries, multimeters wont give you an accurate percentage of Ah capacity. Lithium can sit on the same voltage for 40-50% of their capacity range when charging or discharging, get a shunt.
That could be a good thing, the Kings shop can be sooo addictive. When I go in there, I want everything on the floor :) and the worst part is their new store is only a few minutes for where I work in Perth.

everything about this battery was good, well made, well assembled, with the exception of that nylon packing strap. most likely eve cells given the lazer welded studs and over pressure valve design. they really should have just used 5-10x more fiberglass monofilament tape (this was also lacking, not very much overlap of the tape layers, so the failure point of the tape under load would be the adhesive and not along the tension bearing elements of fiberglass, could of just used packing tape if its not going to overlap a good amount. imo that amount of bulging is normal under most conditions, but the 2 stress concentrations will be the eventual point of failure of this pack. the case of these prismatics is aluminum, and aluminum suffers from metal fatigue. very likely will crack its case and leak electrolyte internally, somewhat dangerous. had a 280ah cell burst in my car, went back through pictures of when i got them and noticed a very slight dent on one of the corners of the cell, likely from being dropped at the factory. dissasembeled the pack and found this one cell had leaked out about 300ml of electrolyte into its enclosure. I actually drove around with it as my car battery for a few months before noticing it had a dead/dieing cell, again lifepo4 is extremely safe. most of the electrolyte was contained inside of the copious amount of monofilament tape i use to make my own packs. only noticed it because my active balancer was going crazy every day after a long drive. another reason why bms' are dangerous, this condition would cause a partially dropped cell, and would overcharge the surrounding cells, more dangerous if those failed with electrolyte everywhere. its some kind of lithium salt based ether compound, bit more flammable than gasoline. some thermal paste of silicone would be better on the temp probe but not that important since it just needs to stop/limit charge below ~4C, its unlikely that this battery would be able to get too hot from lots of discharging due to the current limit on the bms itself, so high temp not that big of an issue, affixing the probe to the cell could cause the probe to fail due to normal expansion/contraction. these are actually expensive cells that kings used. the 30ah to 100ah cells are about 4x more expensive than the larger format ~280ah cells because theyre used in EV mfg. people saying that they got "grade A automotive 280ah cells" are just straight up misinformed. show me an EV that is actually made with those cells lol, they dont exist. those are for large format energy storage for homes/utilities.
@@reddyman6915 lol did you read my entire comment? sorry its long. i would chop the top off of the battery and make sure its not defective like tihs one is. then use it if the cell casing is not damaged.
That's some good information there, thanks for sharing. I will keep using this battery until it dies, unless Kings wants it back for inspection. I am not too worried for the price I paid but it would be nice if the manufacturing plants took a little more care with the construction of the batteries. I have other Kings batteries I am using and I can't fault them, they have worked flawlessly. I have friends that use the Kings batteries as well and they have not had any issues either. Despite what same people say about Kings, I think they have lifted their game when it comes to the quality, compared to when they first came out.
@@TheSimpleLivingAussieI worked at kings for a bit between jobs and the batteries are the one thing I would happily buy from them. They have internal testers to check battery capacity when people return them and I can safely say that 90%+ returned batteries are user error and nothing to do with the batteries. Capacity wise they all performed above the advertised ratings with 100ah lithiums giving upwards of 104-108ah. Kings cops a bad wrap and some of the products deserve it but the batteries weren’t one of them. Whilst they did have some lemons the volume these guys turn over is insane. Every mass produced product is going to have failures.
Thanks for pulling apart your new battery. Friend of mine was looking at buying 4 x 200ah kings to power his offgrid property. Not sure now. Kings was a massive disrupter in 4x4 accessories market. I remember how expensive awnings from arb use to be. The quality is not perfect but it was able to kit out the weekender 4x4 enthusiasts. I have had 3 awnings in 13 years from them. I don’t care if I break them.
I have several friends that run the King 300 Ah batteries and they can't fault them. I have three Kings 120 Ah batteries and they have preformed perfectly so I would recommend them. I have found with all the batteries I have pulled down and tested, the smaller batteries regardless of the brand have been the least quality.
@@reddyman6915 not yet. He was going to buy some from eBay but when we compared the weight of the batteries the eBay ones were kilos lighter than kings. There is also a RUclipsr “organic power” who uses the kings 200ah who has had no problems. Does anyone know what bms is in the larger kings batteries?
For the moment I won't be buying a $1,000 battery to pull apart considering I live on a very low income, so I gotta limit the spending on this channel. But in the future, once the channel starts to pay for itself, I can start purchasing more expensive batteries to test. When my big 48 volt batteries five year warranty expires, I do plan to whip the top off one of those for a look see. Those batteries cost over $3,000 each.

@@ScatManAust You are seriously confused. You say it's hardly rubbish and in the next breath you say it could burst into flames, which to me proves it's rubbish. You sure have been playing with something for a couple of decades.
I think that battery is great value for money and I would buy another one again however, having damaged cells is not acceptable regardless of the price. I do plan on getting some iTechworld batteries to test in the future, see how they stack up.
I would be giving you a refund if you showed me that regardless of you tearing it down . And then making dam sure no more units are constructed like that .
I paid $170 for this battery, it was on special so thought I get it for some tests. I do have other expensive ($3,000) high end brand Lithium (LFP) batteries, which runs my 48 volt system 👍
Most companies would be resellers, so possibly wouldn't know what is inside. A card or barrier on the outside could stop the strapping deforming or even ripping the outside cells. Had you used that battery? The deformation looked to be greater than 5mm..
The battery is only one week old and hasn't realy done any work. Just been charged up and put on the 12 volt system running the cabin water pumps. It hasn't done any proper cycling yet.
This is part of the reason for doing videos like these, if we find issues, it gives the supplier some in site so they can follow up with there quality assurance and helps make a better and safer product.
@conradkous4170 something doesn't sound right there, they should run a fridge. My 24 volt test system is running two 120 Ah Kings Lithium batteries and that runs the 1,800 watt inverter that supplies some of the loads in my kitchen. It runs the microwave, air fryer, toaster and rice cooker no problems every night and every morning. So far after more than six months I can't fault them.... yet.
These are rubbish assembled by the lowest paid worker in China. The cells are likely to be C grade or worse, or even second hand, which is why the cheap thin aluminium busbars are heat welded over the screw terminals. I can't remember a worse quality or workmanship battery teardown.
Most batteries are welded terminals now, hardly anyone is using screw terminals anymore which is a pain as it makes it harder to rob cells from batteries. Not sure on the grade cells that have been used in this battery so I can't make any judgment on the cells. I'm doing a capacity test on the battery so we see what it comes back as.
That's going to be the dumbest thing I've heard today When you get the Chinese to make something if you pay peanuts you'll get monkeys you pay good money they'll give you the best quality😂 which no one can compete with you shouldn't take for granted the country that makes all the stuff you can consume everyday that your country cannot
Just a tip for your videos, instead of telling us what you're going to do, just do it. We can see what's happening. For example, im going to move the battery over to this table because of the reflections. It's irrelevant to the video and wastes the viewers time. Just cut those sections out when editing and you will reduce the video a good bit. It will make your content easier to watch.
A bit dramatic. LFP batteries will explode but they take a lot of encouragement. They usually just get hot and emit a lot of carbon monoxide and hydrogen
If your not a "techy guy" then how can you comment on such things as the temperature sensor etc. To me the quality and build seem fine. Take anything out of it's protective casing and it will look exposed and vulnerable.
WTF - you think the quality and build are fine???? You need to get out more. These are rubbish assembled by the lowest paid worker in China. The cells are likely to be C grade or worse, or even second hand, which is why the cheap thin aluminium busbars are heat welded over the screw terminals. I can't remember a worse quality or workmanship battery teardown.

Gotta get me a king’s knife lol …..Got a 60 AH so will be looking forward to the next video .
I bought 4 of these, blew one of them with a direct short, now the bms slowly drains the cells so i ripped it open and removed the bms lol
Did you have the same issues with the strap being to tight and crushing the corner of the cell ?
I only managed to get the top off, it refused to slide out which is why I'm here, i need to cut it open to find out 😂
Not bad - the strapping could be improved to reduce stress on the cell, but the thermistor isn’t really an issue - bonding to the cell make stuff all difference.
Yeah the thermistor would probably be fine how they had it, I just like them fixed a little more securely to the cells.

@@TheSimpleLivingAussie Hopefully they will be a responsible seller, and take steps to improve the product with their supplier.
This is part of the reason for doing videos like these, if we find issues, it gives the supplier some in site so they can follow up with there quality assurance and helps make a better and safer product.
Have 2 x 120ah,absolute rubbish,save your money,will not even run small fridge for 2 hrs past sundown,240 ah total
@conradkous4170 something doesn't sound right there, they should run a fridge. My 24 volt test system is running two 120 Ah Kings Lithium batteries and that runs the 1,800 watt inverter that supplies some of the loads in my kitchen. It runs the microwave, air fryer, toaster and rice cooker no problems every night and every morning. So far after more than six months I can't fault them.... yet.
These are rubbish assembled by the lowest paid worker in China. The cells are likely to be C grade or worse, or even second hand, which is why the cheap thin aluminium busbars are heat welded over the screw terminals. I can't remember a worse quality or workmanship battery teardown.
Most batteries are welded terminals now, hardly anyone is using screw terminals anymore which is a pain as it makes it harder to rob cells from batteries.
Not sure on the grade cells that have been used in this battery so I can't make any judgment on the cells. I'm doing a capacity test on the battery so we see what it comes back as.
Manufactured in China
That's going to be the dumbest thing I've heard today
When you get the Chinese to make something if you pay peanuts you'll get monkeys you pay good money they'll give you the best quality😂 which no one can compete with you shouldn't take for granted the country that makes all the stuff you can consume everyday that your country cannot
Just a tip for your videos, instead of telling us what you're going to do, just do it. We can see what's happening. For example, im going to move the battery over to this table because of the reflections. It's irrelevant to the video and wastes the viewers time. Just cut those sections out when editing and you will reduce the video a good bit. It will make your content easier to watch.
Its a bomb. not a battery!
A bit dramatic. LFP batteries will explode but they take a lot of encouragement. They usually just get hot and emit a lot of carbon monoxide and hydrogen
Yes definitely a bit dramatic, It was more aimed at the messy build quality.
If your not a "techy guy" then how can you comment on such things as the temperature sensor etc. To me the quality and build seem fine. Take anything out of it's protective casing and it will look exposed and vulnerable.
those cell/s were clearly stressed by that band. would be better off just with the tape. might be worth top balancing given the voltage differences.
WTF - you think the quality and build are fine???? You need to get out more. These are rubbish assembled by the lowest paid worker in China. The cells are likely to be C grade or worse, or even second hand, which is why the cheap thin aluminium busbars are heat welded over the screw terminals. I can't remember a worse quality or workmanship battery teardown.
I was meaning tech savvy as in using a computer. But in regards to Solar and Off Grid Living, I have 25 years experience.
Are you on drugs😅
@@WayneMcKenzie you're*, it's*
Bloody Chinese made lol 😂they don’t even care
