So its been a while as I been busy with other things.. so had free time to near finish the 12v 330ah battery.
Between the cells I have sillicone bond mica 2mm and when I make the case which will be stainless steel 316 1.5mm.
I made rectangle box out of black 6mm plastic polyethylene hdpe to be...
Yea I'll be doing the 2p4s and config (d) but I just need to get a few more busbars as docan only sent me 9 and the config asks for 11, that and need to get some cable for the negative to top balance the cells but cant do that till next week. But thanks so much for the information.. super helpful
its a jbd custom bms, muller just asked jbd to make him a custom made one. So its the same as the 200a jbd 4s bms and if it keeps it online all the time then the muller one would also its just a better version of the 200a and its 50a more.
Watch this review on them -
He told me its 2000 at 3c the ultra high one is the same as the toshiba scrib cells but instead of 20ah they are 40-50ah. Can you link me the alibaba that has a sydney warehouse?
Hi All,
I'm from australia. Love technology.
I designed a camper trailer and me and my dad built it which at some point
I'll do a show and tell. I'm at the stage of building the electrics up on 12v.
I plan to have it 95% based off 12/240v and 5% gas for backup.
Just wanted to join to seek some...
So Im charging my 8 cells in 2p4s using a 12v 40a lithium charger while my 250a jbd 4s bms is connected.
In the settings I put down cull full voltage as 3.6v. My question is in the balancer config what do I put down as start voltage - currently its
at 3.45v with a 5mv delta to balance with...
I think your right in that it is 150 or 160ah lithium cells in 2p4s.. gee Id like to have that but I just asked docan - daisy and she said all the 173ah cells are sold on ev and catl and been out stock for a long time... 160ah is still in stock which I could get make it... Though only 160ah b...
So there is a Australian business called mullerenergy that sells cells, pre-made batteries with custom box, chargers and bms's.
They are selling a jbd 250a 12v 4s but its on backorder but from what I thought you can only get 250a in 5s+.
I can't find anything on the internet about a 4s 250a...
I saw a video that looked like he had lots of thin cells.. so I think its what @BiduleOhm said its 2p4s and I'd say its 160ah. Sucks though all these shops buy all the 160 and 173ah cells and allot of them and now you can only get b grade cells
I got the blue one it goes from awg 10 to awg 1. Ive just recently used it on awg 2 lugs and Anderson connectors and it works really well. It may not be the same brand but its same thing.. you can change the settings.. pretty handy tool
So I been looking around for a high voltage solar panel for my camper trailer thats 12v but the best I seen was 27voc which is good..
but then I saw a 200w thats 44voc and looks really good measurements wise but its saying its 24v not for 12v.. My question is
does this matter.. I read an article...
So I got 8x 160ah eve cells with the welded bolts.. They all look really good no issues with them. I got them from docan power.
My question is how do I make them into 4s8p.. Can I do it like this in the picture or does it have to be in 1 line.. They will be in 12v
Can I put in parallel a 330ah lithium 12v with a 140ah 12v lithium both with same voltages.. tho one the one thats 330ah has 250a jbd bm and and the 140ah has a 100a daly bms.. I know based off the manufacturer of the 140ah it can be put in parallel but question is can I put the 2 different...
So I got a 300w 70.8v solar blanket thats etfe.
I cant test it using elejoy cause of the voltage so used a multimeter and victron solar controller.
The specs of it is:
300w
70.8 voc
60 vmp
5 imp
5.5 short circuit
So first with victron it shows 58 voltage - im guessing thats voc or is this...
Hey, So I got my 8x eve 160ah cells and they are great condition.. I checked all the cells with a multimeter and they all on 3.29v.
But I got some newbie questions..
I got a jbd 250a 4s bms from - https://mullerenergy.com.au/product/12v-250a-jbd-smart-bms-with-bluetooth/
So my main question...
Ah yea sorry I meant 4s 2p, Also I was watching a video on how to tell if they are a grade.. docan stated these were A grade eve cells and they do look nice.. but I just checked with a square that there is very very tiny buldge.. I lifted the black top of to check if there was 2 barcodes which...
The reason why I'd go 600ah is because I'm planning to have the camper trailer to be 95% electrical and 5% gas as a backup.
So 12/240v hot water system, I plan to use a induction stove for cooking, 1x 47L fridge, 1x 90L fridge/freezer, 1x 24" 12v tv, lots led lights,
12v travelbuddy camp oven...
The other barcode isn't scraped.. I just asked daisy at docan about the barcode and she gave me a site to decode the barcode.. and the barcode comes up with that its a eve battery with manufactuer date off 22/September/2022 so Im guessing they are A grade. The 515.5wh is just stated for the...
So I've ordered 8x eve A grade 160ah cells from docan.
My dad is going to make a box for me out of 1mm 316 stainless steel.
Issue I'm having is trying to find the battery studs that are on the outside of the battery box and connect
inside to the cables. I found one type but unsure how good they...
the extension is 10m or 32ft, I did a test with multimeter and it was testing same voltage and current with and without the extension.. the max on the blanket can charge is 25ah into battery, 5a current the victron is 100/30.. based on last year I tried it same month, about the same temp and...
I see.. but so far for 2 days ive tested it and its showing the same volts, same current, same watts.. when I test another lower volt panel with elejoy it tests at its max watts "180w and max current".. plug that into victron and it drops to 122w, and 1-2a less current.. 98% effieciancy on...
How would I make a 300ah battery using 50ah prismatic cells?
And how big would it be.. would it be larger then if I used 4x 300ah cells?
I know if I used 8x 170ah cells it ends up being the same size if or close to same size
if I was to use 4x 300ah cells.
Just trying ti figure it out..
So I thought I was calculating this right but I'm thinking I'm wrong.
I was testing a solar blanket, it had a 30a powerpole anderson connectors obviously not the real brand but a cheap copy. and I think awg 13 cable from the inside lil box to the powerpole. It was testing good at 192w for a...
I been looking around for the 173ah eve cells, docan are sold out, I spoke to the eve alibaba store they said they have them but they don't come with studs they are welded/soldered ones.
They are pretty much sold out everywhere.. Looking for a legit if possible alibaba link that people have...
Hey All,
So me and my dad made a custom made camper trailer.. its 80% complete.
The trailer is based off a design from a company called Drifta in Australia, they use to make camper trailers
called Drifta dot 6 that was built on a 6x4 camper trailer with a canopy and rooftop tent.
The last Dot...
I'll prob do 2p4s then as I only have 1 bms and costs too much to get another one.. On that pdf in the 2p4s I like B or D but questions is it says to use heavy duty bus bars.. what does heavy duty mean? I got the ones from the factory from docan. Where would I be able to find heavy duty ones?
