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...

So.. Ive learned allot over the years about solar till I saw one picture that screwed me up. I talked to Nate from Explorist.life about the picture if it was fake.. I'll attach it in this. But it was 3x 200w shingle black frame panels in parallel. The specs on the panel is - 27.3voc, 23.1vmp...

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...

So I made up some bus bars and doing 2p4s. I'm trying to figure out where the bms wires go.. And in the bms app it only says there is 4 cells not 8 is that correct with this type of setup? Also the rj45 lcd screen that came with it is all connected but it comes up with connection error.. Can...

So I'm in a facebook group that's dedicated to 12/24 volt hacks and tricks or something along those lines.. Pretty much diy people that I seen no one that really know what they talking about. So one guy was asking about lithium batteries and what brand is good and one popped up called custom...

So for my 8x 160ah eve cells I was thinking of doing 2p4s but a few people told me its better to do 4s2p.. Issue is the bms I got is nearly sold out its a muller 250a jbd custom bms thats 4s.. I found another JBD thats 300a 4s with bluetooth same as the muller one but my question is can you...

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...

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...

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

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...

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'm looking to get lishen 130ah cells. If I go with 4s3p that's 12 cells which would make 390ah but I think that is a bit too much, is it possible to use 10 cells for 4s2.5p to make 325ah. Also these cells are very long can you put the cells down flat or do you need to put them up? Thanks for...

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...

So been chatting to daisy about some cells I may get.. But I found in Australia a business manufacturing lithium cells only 52ah that I know of. The guy imports the lithium powder from Europe, America or gets it locally in Australia and manufactures them locally. They state they are military...

So I saw a video of a guy saying his battery that was 120ah Itechworld lithium that has 150ah discharge (peak 270ah, 175ah over 5 min) he put a airfryer on it with inverter 1600w and the airfryer was 1500w it showed for 240v (Australia) it was using 155ah. His friend who had a 280ah lithium with...

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 there is a guy in australia selling lithium batteries, he doesn't compress them and says the cycles at 100% are 2000-6000 for 280ah and 333ah though he has a picture stating the 330ah battery rates to 337ah.. I've not seen that.. most I seen is 318-320 on 300-301 battery cells. He uses a 5a...

I bought a solar blanket in Australia that is 300w and 70.8v max open circuit, 60v vmp. And it does just that. The blanket cost $750 which is pretty good for what it is and produces in sunny and cloudy days. In Australia there is only 1 other business that sells a high voltage solar blanket but...

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...

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...
