KINGS 200AH Lithium Battery Test and Teardown

[@anned8634]

the loss of amp hours could is likely loss by heat from the terminal. heat is power being converted to heat.

[@stephenrogers9664]

Honestly for there price you can’t beat them. Kings have def come a long way.

[@sarin62]

No they haven't.

[@MikesManCave]

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.

[@72superlead]

How'd you go mate?

[@jesus_built_my_hotrod]

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

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.

[@guywhoknows]

Cheaper ones are at .2c brand batteries are .5c

lol, this is a cheap cell battery

[@hally271088]

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.

[@FutureSystem738]

Glad it’s not my battery LOL :-) THATS a real torture test, (with pretty impressive results!)

[@evil17]

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

[@Browneye2566]

Good review Craig. It's important to find these manufacturing problems so potential customers can make a more informed purchase decision. Well done.

[@Peter-b6e3x]

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 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?

[@AlexSwan]

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.

[@NatesToolbox]

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.

[@GazandShazSteer]

Good review, Craig. It obviously wasn’t the lug! I will check the 6 kings units I have. Cheers.

[@popeyebob9007]

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.

[@only1envy52]

How did it go?

[@nigelcharles511]

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.

[@FutureSystem738]

I missed it. Where was he talking about fuel and/or generators?

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

[@bleepbloopblahp]

Excellent video. Thanks for sharing. I really appreciated your testing and teardown.

[@larrybell1305]

Thank you for the No Bravo Siera review. The hot terminal is enough to keep me from buying it. If they cut this corner too close, what else?

[@defenderzook]

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…….

[@cdonuts7335]

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!

[@craigsolaradventures]

I’ve torqued hundreds of battery terminals, believe me I didn’t screw it up. It was stuffed from the start.

[@parabelllum8733]

For the money , its an A grade option . Where else do you get 200 AH for $699 in a "good enough " quality product

[@Peter-b6e3x]

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

[@parabelllum8733]

Did you watch the test ... he gets 193.9Amp hours out of a 200 AH battery claim - Close Enough for me . I also successfully ran my fridge for 4 days without recharge on a 120 AH Kings Battery . Thats good enough . These batteries have passed most tests I have seen . Another test done by Lock your Hubs got 136 AH out of a Kings 120 AH Lithium . I suspect Kings are putting a ton of pressure of overpriced competitors .@@Peter-b6e3x

[@evil17]

@@Peter-b6e3xCodswallop, I dont know where you get ur info. 1. he just demonstrated this battery still pulling over 167A at 9.99v with 198.3Ah already drawn from it. 2. Most lithium batteries are shipped with around 40%-60% SOC. 3. This Kings battery has a 200A continuous BMS rating & it works. 4. Many fridges can run down to 10v-10.5v on a low voltage setting if the battery has the Ah capacity left to run it that low, and this one surely shows it has that capacity still drawing 167A at 9.99v. 5. Check out reviews on Australian Itech batteries, over 3 x the price with overrated & false claims of output around 85% & problems when used under bonnet as advertised they can. 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.

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%

[@seanfrench4395]

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.

[@CraigRichards-qp3pg]

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.

[@evil17]

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]

He clearly demonstrated in the video that the temperature dropped once he tightened the terminal.

[@budmartin3344]

@@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.

[@GazandShazSteer]

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.

[@sparkletornado5890]

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.

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.
