- The new and improved 300ah kings lithium battery is definitely worth the watch. I was quite surprised at what I saw inside. Also keep subscribed if you'd like to see what I do to the 200ah Version on a new video out soon

Great insight into the 300ah battery as I was literally looking at buying 2 of the 120ah ones and running them in parallel to achieve the 300ah constant draw knowing this was only 150ah but great to know it actually will allow the 300ah, win win
Cheers
Good specs and results for the 300 mate and ya still giving that inverter a workout. I’ll still go 3x120ah so I can fit it all in the MT1 electrical cabinet.
Yea mate definitely makes sense to spread the load between cells too. No need for too big of cabling too
I was inclined to think the same way until I saw this vid, pro’s & con’s of each I guess, if u have 1 suspect battery out of 3 you can still get by on the 2 remaining, but being able to have one battery to run a 3k inverter is pretty impressive, & less cabling could allow for a very short run of heavy gauge cable to inverter directly above the battery in a canopy setup.
A good video, would have liked to see a bit more about the inside (like other you tubers do ) . but non the less i liked the video.
Will be doing following videos on my 200ah battery. Going to pull it out and put it inside another battery case. The one they're in are wayyyy too big. No need for battery case that large.
Good job & vid mate. Yeah, the Kings lithium batteries seem to be pretty good for the price point & better than many others that are much higher price. I like that they have the prismatic cells, I thought they were cylindrical, maybe its the new blue top format. Seems like a pretty good BMS too, it would be good to get some more details on that. I thought that Kings had dropped the ball with the 300A lithiums because they only had the same input/output of the 200A model until more recent, at least this is a drop in for a 3000w inverter install now. Thanks for sharing. Cheers
Yea I gotta admit I was not expecting the good BMS or the prismatic cells. Definitely worth it now
Anyone thinking of buying these should know that if you have a warranty claim, as I have, they have to be taken back to the nearest store and left for testing for 1 or 2 days, which is great if you, like me, live a fair distance from your nearest store. For me it's a 240km round trip to drop the battery off, and then another 240km round trip to pick it up and don't bother asking to book in so a simple charge test can be done same day, main call centre will not give out store phone numbers. Oh, and compensation for travel, not gunna happen! I've found it easier to deal with Chinese Ebayers.
Thats such a shame mate what happened to the battery?
@@WEEKENDER4X4 It's one of a pair I bought to run in series and it won't charge over 13.7 volts from new. First time in the system I set charge voltage to 28.4V and when they got to about 27.8, they dropped the load and I don't like doing that to my inverters etc. I'm full time stand alone solar.
@mal4383 not good mate. Wish I knew how to help you just don't have much experience in 24v systems. I know the BMS have to be specifically rated to work in series. All of my systems are parallel 12v
@@WEEKENDER4X4 All good mate, I'll get it sorted by hook, or by crook. After living for ten years on two 400A/hr sets of pre-sulphated AGMs from Low Energy Developments I'm not letting this lot get away with it.😁
It took a while, but I finally have a very satisfactory outcome thanks to new manager Ezra at the Ballarat store.
Picked up one of these yesterday, hopefully I can find a suitable box to put it all in.
I recently purchased their 120ah lithium and honestly it’s an amazing battery so I’m not surprised that the 200&300ah batteries are great also
Yea mate they're really good batteries
Awesome review.
A quick question would you mount the battery on its end? Wondering if it's packed well enough so internals don't move around. It's going in a canopy and will be driving on corrugated roads plus 4x4 driving. Thanks
Probably wouldn't mount it on its end just to be safe.
Thanks 👍👍
Hey Champ great video, could you run 2x 300ah Kings lith batteries in parallel? For 600ah total amp hours?
Yes mate 100%
Great video. Very informative.
So, where do you get your cable from? Is that welding cable?
What do you recommend for drawing that sort of current?
Yes welding cable from Springers solar. Minimum 50mm on longer runs.
Great videos mate. I've ordered a 300ah one after watching this. Do you have any recommendations for a 240v charger?
The 240v charger I think is best is 75a charger/inverter 3000w renogy. Best value for money. If you don't want to spend big just get the renogy 20a 240v charger.
@@WEEKENDER4X4 Thankyou, i will check them out.
Good video mate, have you ever put a temp wire on your battery to see how hot it is getting? Cheers.
Not on this one mate I borrowed this one off a freind for the video. But on my 200ah one I used a laser temp gun and they never got much over room temperature even on big loads. BMS got about 10-20c hotter than ambient temp
Good Video, I have the 6 blacktop Kings 200Ah in a home 24v setup. They have been in use since November last year so far so good.
My capacity test using a Victron SmartShunt was spot on the rated capacity of the batteries.
The disappointing bit was no included documentation. Would be nice to have information about how many batteries allowed in a series/parallel configuration.
I believe they all allow for up to 4 batteries in series or parallel, so ok for a 48v system too.
Hi, new to researching off-grid, initial plan was/is eve diy, then noticed a lot of kings on marketplace, which eventually brought me here. Ta for the simple info, some explain like we all understand, however, as someone who's built his own eve 280ah, curious why you've gone these pre-built kings (sponsored?), & if you were setting up just for your house (not mobile), would you do the same? Cheers!
Hey mate I'm too far small pf a channel to be sponsored lol. I just got one out of curiosity to see what made them tick
@@WEEKENDER4X4 Oh, I seen the 200 vid, + all the kings gear in the rigs (never heard of kings until yesterday), then seen this 300 vid, thought you must have moved away from diy for some reason.
So the 2nd part of my Q, just for home, if rigs weren't a consideration?
Thinking of doing 16s, sussing out the cost of all the bits vs prebuilt.
@Lana_Warwick would definitely buy it from Ali express and DIY a kit together for home applications
@@WEEKENDER4X4 Thank you
@@Lana_Warwickyeah, definitely go the eve diy for a house setup, & check out the JK BMS with active balancer & Bluetooth, I have a few JK’s and they seem to work & balance well. You might want to check out Andy’s Off Grid Garage for all things Solar & battery related if ur still researching, he has a lot of good info.
Kings also seem to randomly sell side terminal or end terminal 200Ah batteries - I have 2 of each, fortunately bought 2 at a time so have 2 of each - no real documentation as to options.
Yep - for "full power" draw hu-uge (short) cable is needed to the inverter..
Question is - Can these reliably be used for winching - parallel up a couple of 300s. (I have a 200Ah from Renogy in the ute for camping power - just a 1kW Renogy PSW inverter ) - have resisted hooking winch up to any of my lithiums..
Honestly two of these in parallel I think would do it quite easily. I mixed my winch once and it only pulls 260a full load.
I think 2 would have the power to run the winch reliably, the main issue I think is that I would not recommend lithium for under bonnet use because heat is not good for any battery really, & there has been a number of failures of lithium under bonnets & I dont think the BMS’s would be happy about the extra heat either. The other issue is, if u mount the batteries in the rear or further away from ur winch, it is going to cost a fair bit more in extra heavier copper cabling to overcome losses from the length resistance, but that could work.
Just checked my 2 x 300ah Kings batteries and they are both blue tops. so the same as yours and supposed to do 300ah discharge. why are they advertising with black tops? is that the old one?? have them installed in 2 campervans with 1500w Kings inverter. they work flawlessly, have big respect for there inverters. we only use 240v appliances, kettle induction..... would like a 3000w one, but that footprint is to big for me. for 1249$ for 300ah, this is a bargain.
I think the blacktops must be the older versions
@@WEEKENDER4X4I think ur right, I got a 200A black top one week, & then two more blue top batteries arrived a week later, think I got the end of the black tops before getting the new blue top batteries.
Do we know if the black top batteries have those nice prismatic cell in them?
@@evil17 black tops are cylindric, but the newer black tops have the same high amp output BMS. That's my understanding anyway.
Max sustained discharge is 150. Max is 300, but only for a few seconds or minutes at most. The battery will possibly get overheated at that rate of discharge.
Not prismatic cells. They will take it all day long. The BMS will overheat
Do you recall if the cells had welded bus bars or bolt on? Specs say 8mm studs but you have seen first hand inside!! Want to buy and pull apart for different configuration
They're laser welded
@@WEEKENDER4X4 😔
35mm2 cable asking 300a over 3m return and a 175a Anderson connector...
Yea sure is a lot to ask of it but still does it for short periods of time
Thoughts on running kings 2x200ah in parallel vs 1x 300ah.
Pricing works out similar when on sale
May aswell get 2x200ah. More capacity and less stress on the BMS's when running heavy loads
@@WEEKENDER4X4 thanks mate, any tips on where to sourcing wiring/lugs etc?
what size wiring are you running out of curiosity
@Luminati- running 35mm for all the short runs, 50mm for all the longer runs and inverter cables. I get everything from springers solar in lawnton now. Best place for all good quality gear.
Is this an updated blue top battery to the black top one online? Have kings supplied it as a test one or did you buy it?
These batteries are bought, non sponsored at all. I'm only a small channel lol. And yes updated bluetop batteries with new BMS inside
Good to know. Are the blue top ones available now? Haven't been in to the shop to have a look yet1
ask them to open box, in Perth they open the box to show its blue. have 2x 300ah blue ones that is 3 months old. work great.@@jameswilliamson1312
Do I go redarc or kings? Seems your having a good run with kings
Kings batteries no worries (lithium). Renogy for battery chargers etc. Victron energy shunts are the best
Thanks mate think I’ll be getting one of these tomorrow for my caravan
Hey mate I did get a battery just wondering to charge it do I need a lithium charger or would a standard charger be okay
@@Mr_RPEyou can use a standard charger but it is not ideal if you dont understand how to charge lifepo4 correctly, & you will probably end up damaging it at some time. Ideally you should get a proper lithium charger, they use a specific algorithm for Lithium charging.
If you are referring to a DC-DC charger for ur tow vehicle to van charging on the go, you can get combined alternator & solar chargers, but I would use a seperate charger for the solar on van (if u have any solar) so it can work independently of the vehicle DC-DC charger & charge ur batteries more efficiently while driving.
Lifepo4 batteries are best charged to between 13.8v & 14.2v and then floated off to 13.4v to 13.6v if you want to keep them in a full SOC & ready for action. At 12v alarm bells should be going off & they are virtually exhausted, so dont take them down to 10v as in the manufacturer specs, it is not necessary or good for them for the last 2-3amps, conversely taking them over 14.2v is not necessary either & is where more damage to longevity will occur. Do ur homework, lithium is a game changer & worth the research. Hope this helps. Cheers
@@Mr_RPE you've probably figured it out or killed the battery but you need a LiFePo4 charger. they have a different charge curve and voltage than a lead acid charger. lead acid charger will more than likely kill the battery
I don't believe that to be true. The AGM pwm charger just won't get it charged up to 100%.
You'll achieve about 90% ish charge 13.5v ...which in actual fact is better for the battery life.
Charging between 20%-80% is favorable
b@@UnacceptableViews
just a thought but even at 100% efficency and no loss in the cable 300amps x12v =3600w. probably just the inverter tripping. don't the the battery is the limiting factor in your test.
Mate about to take the plunge on a kings 300ah lithium at $999. I don’t think i can go wrong.
Hi mate compared to the 200ah and 300ah which is best one cheers greg
300ah
@@WEEKENDER4X4
I.m looking at both for my campertrailer just run fridge and lights
Do you know how to find the batch number? My 300ah started to bulge up the top and it is slowly losing charge by itself. They have asked for a picture of the batch number on the battery but I can't find it??
And I threw away the box
Sorry mate no I have no idea where the batch number is 🤔
The new 300ah lithium like the one your using. How many hours will I get on using a electric trolling motor which draws 21 amps or 504 watts. Cheers Don.
P.S I know nothing about this.
Roughly 14hrs
@@WEEKENDER4X4 thank you so much for your reply now waiting to see special on this battery and buy one also what charger should I buy. Cheers Don.
@@collowood best bang for buck are the renogy DC DC chargers. You will want a minimum 50a charger for that size battery
@@WEEKENDER4X4 thank you so much
@@collowood no worries mate have a great day 👍
Could one of these run a Dometic Harrier Lite please? It’s only a little 13ft pop top van.
Yes it could with the right inverter. But not for too long.
@@WEEKENDER4X4 many thanks. I'm hoping to fit 2x if possible
What dimension are they inside? Thinking of making a new box for them
No idea on the 300ah, that one I did the review on is my freinds one. I have the 200ah that I've got a new box for.
@@WEEKENDER4X4bugger. I’d love to know . As the kings box is too big for my draw setup lol
@@claytonfry3752 they're easy enough to pull apart.
Its probably only got a 200A BMS - you wouldn't wanna go above that normally even thru a 2000w inverter? Im soon making a 310a prismatic with 6000 cycles for under $900 inc 200a bms
Watch the whole video, it's a 300a BMS. The reason I was getting voltage sag was from undersized cable.
Also have built multiple lithium batteries in other videos on the channel, love using the Muller 250BMS. AWESOME bit of kit
@@WEEKENDER4X4 ive heard EVE niw have 320a cella - i like these as their footprint is narrower than a ready made unit - i was consider just a 200a JBD bms
Are you purely DIY or are you a licenced sparky?
DIY
thanks @@WEEKENDER4X4
This gives me the confidence to "give it a go".
Any recommendations when working with batteries/wires?
@@thealterator make sure you use bigger cable than what you think should be used. Make sure your connections are crimped or soldered properly. Take your time
i purchased 2 x Kings lithium 300 ah batteries but my case is a black top one. has there been an update (bought mine about 6months ago) Has there been an update?
Yes the bluetop versions have bigger and better BMS'S
Was just thinking should of the battery bms cut out the battery when discharged to 20 percent batter left to save the battery
No, it will cut out at around 10v, 2.5v/cell, which is dead flat, you need to program that into a shunt or low power cut off device.
@@evil17 isn’t that bad for the cells to get that low
@@Mr_RPE It isn’t good, but the manufacturers state the cells can be charged to 3.65v/cell & discharged to 2.5v/cell, so a range of 14.6v down to 10v for a 12v battery & this is generally the range a BMS will cut the power so any cell does not go over 3.65v or below 2.5v. I dont like taking the cells that low or high, & I would suggest to try and keep them within 3v to 3.5v/cell, ie; 12v minimum & 14v maximum is ideal for longevity & to keep the cells balanced & in a full SOC.
do you recommend anything i can put on my battery to stop the such low voltage on the cells@@evil17
Is it easy to open the battery and close it again without it being obvious its been opened?
Not really. The little caps break easily above the screws
G'day what is the max charge amps for the 300amp kings please?
Would say 100a
150A (1:22 in the video on the side of the battery).
can you run these in parallel
Sure can up too 4 I think from memory
Your making me want to go lithium.
It's definitely worth it.
With my kings 200ah when not using it can it stay on charge ??
You can keep it on charge but not recommended
@@WEEKENDER4X4 thanks
Ont know why they need such a large case. Looks like so much room.
Yea I'm baffled too. Maybe heat dissipation for BMS
Throw the dryer out .
Make her hang the washing on the line
She left anyway 🤣
@WEEKENDER4X4 Nice.
Same here, bud.
On to a better life
Trust me, it's a good thing.
Can they be run as parallel x2 !
Yes
They claim can be run up to 4 in parallel or series.
Could have put all that in a smaller box, way to big for the Internals that are there
I agree 100%
