I thought I’d post an update and thank everybody who had replied. The supplier where I bought the battery was extremely helpful and provided me with a full refund immediately. He even offered a direct swap with a more expensive, however, lower amperage battery, which, with hindsight I regret not...
Correct, however checking with my eBay purchases the fixed solar is actually 300W (has claimed however I suspect that to be highly optimistic)
I haven't actually purchased the 200W folding panel yet however I have a credit with the supplier which I was going to use on this. I have been reading...
HAHA -definitely short-circuit blues however I don't think all is lost. All cells appear to be fine, just the BMS is toast. Landfill will have to wait for another victim.
I'm building a simple 12v battery for a DIY toolbox power station. I've ordered 4 x EVE LF304 cells and I've also ordered a 300A BMS JK-B2A8S30P
The planned configuration is a simple 4S1P which will give me 12.8v and 304A however I've only just realised by reading the specs (attached below)...
I've been quoted 83-85USD (before shipping) from China for EVE 304AH Grade A cells. This seems like very attractive prices compared to what I have seen in the spreadsheet posted here some time ago. I am building just one 12v battery at this point in time and this order is my set of the system...
Thanks for your message. I've heard that buying direct from Eve rather expensive for shipping small quantities. The quote I have for DAP shipping to Australia is only 77USD which seems pretty fair. As mentioned in my post however I would prefer to have DPP and not have any extra sneaky charges...
G'day gang,
1st post on the forums. Looking forward to taking part and hopefully contributing to the solar community ☀️ I'm based in Melbourne Australia and despite it being known as the sunny country, here on the Eastern Coast it's been more rain and floods this summer which debatably beats...
Thanks Steve for your informative reply. I was unaware of Gobel Power and now I've been watching the reviews/tests from Off Grid Garage
Andy seems very enthusiastic about global as a supplier so I will include them in my research. I've reached out also to both the other vendors for a...
I'd like to order nickel sheets to hopefully spot weld onto the terminals of this battery pack. Can anyone advise what thickness I should get?
Options seem to be from 0.3mm to 1mm thick. The pack output is 135Ah
Again, I agree with all your points. However the scope of my project has grown since I purchased the 4 x 304 A/H cells. My aim is to make a powerful portable all-in-one universal powerstaion for use on film/photography sets. (see attached pic) The added bonus will be to take it away camping and...
No, not necessarily. But perhaps I would have purchased less powerful BMS had I been aware.
I’ll be using the inverter and battery to operate cinematography Lighting equipment. The runtimes would not exceed 10 minutes in one session generally without powering them down
Okay braintrust. I'm at a loss now.
I've tried three different methods to kickstart the battery. No luck with any of them.
12v 1.5A charger from a HDD
12v lithium jump starter pack (according to the flashing LEDs, the house battery was too low voltage :fp)
DC-DC charger connected to solar (it...
This is a case of being a noob and not paying proper attention to what I was doing :(
I'm gathering equipment to build a all in one solar generator (battery, inverter, DC to DC and AC charger) I just received the last component which was a DC-DC charger with inbuilt MPPT solar.
Before the sun...
LOL, yes, I've been doing lots of research into various components and trying to educate myself along the way yet the lesson learnt today will stick around for a very long time. Unfortunately it may have been an expensive lesson!
The battery was at full capacity as it has been charging via a...
As it is a brand-new battery I had the warranty card on hand and unfortunately it claims that in the case of a short circuit of the battery terminals it won't be covered.
This might be my next step to take however not having any experience with lithium batteries I will look carefully into that...
It reads 0v at the terminals and it has a circuit. When I plug a 12V 1-5A charger in, it fluctuates between 30-400mV (any reason why the DC charger only puts out such a minimal voltage when connected to the battery?)
The SOC of the battery was 95% at the time of the short. (I was charging it to...
Thanks, you are correct in your assumption.. there seems to be little information about this particular battery online. I suspect it will be just a rebadged version that is mass produced in China. This is the specs
I'm considering purchasing a 3D printer (Creality Ender-3 V3 SE) and using it to print (amongst other things) parts for my solar builds. The first project that has driven this idea is for a custom bus bar incorporating ANL fuses. The file can be viewed here: Thingiverse Fuseholder for 5x40...
I regularly see 100, 120, 150, 200, 300A/h etc batteries in the marketplace but given 280A/h cells are relatively common, you rarely see them as pre-built versions. Can anyone explain why?
The width of the existing straps are 50mm. however I’m having trouble sourcing this size in Australia. I thought the safest bet would be too reinstate the same materials as came from the factory. One concern is however would be that the 50mm wide strap would hide the terminals, making it...
So I did this. I went back to the supplier and figured I'd make them an offer on the dead 135 Ah battery and see If I can performer Frankenstein and bring it back to life. They were happy to take $50 cash as I think it was just going to end up being be a door stop. I figured that if necessary I...
Hi brains trust - I'm considering a DIY battery build using cells purchased from Alibaba.
I've noticed that on some listings you Start order request and the site offers an initial price with shipping to be negotiated with the seller.
However on some other listings you simply Start order and...
Thanks for your comments. That's a good point about the possibility of tripping the battery and something that I'll need to be watchful of however I'm future proofing the system as I'll likely swap out the battery within 6 mths for a 200a/h or greater unit. Plus the price, features and size of...
