apologizes in advance but... @Alkaline !

I don't take advice form scam artists like ray that go around pitching docan and calling other companies scams mean while: https://diysolarforum.com/threads/docan-power-bad-experience-beware.61866/post-773779 and then makes videos saying a fake docan is selling counterfeit, swollen cells but...

The heating mosfet burned up and now stays open the whole time so I effectively have a NON heated 200 amp bms now.

I have dealt with 18650 battery store many times and it has been a striaght forward process. Good products and service. I have been buying 105 cells from them, probably up to 300 or so thus far. If you aren't happy with 18650 you can try sunfunkits another good vendor that I have been dealing...

Sand off the top layer to remove the anodizing you will get much better results. These terminals have a thick layer of anodizing that adds resistance.

Ok well I just asked again and after mentioning this thread I got it down to 77.00/cell! So almost $400.00 cheaper(y) $4782.62 or $99.637 / cell shipped with all the fees. This is shipped to VA. Not too shabby, I'll contact EVE official store and see what they say.

how are you getting $91/cell I just got a quote to Virginia and shipping + sales tax + alibaba fees were 109/cell this is for 48 of the 280K cells

Out of curiosity I got a quote from Lampard Lei-HZ on the eve official store for 48 cells and it was $4690.00 after all shipping fees, taxes, and alibaba fees and delivery to me. So they will sell 48 cells. $97.70 / cell delivered. For the same amount Luyuan was $5256.00 that is $109.5/cell...

For real! Like he just waits for posts to start bashing. We get it, ok you'll probably have better success from the sellers with test reports, but not everyone can afford those! On the same token, I have to admit some of his hunches turn out to be true 🤷‍♂️

Clearly you don't have either, there is plenty to not like with the dual pole cells: I asked this a few months ago and never got a striaght answer, it was regarding this video: So I kept searching and the know-it-all @Alkaline said I was nuts and to check Andy from offgrid garage, well lo...

I followed alkaline's advise and cleaned my cells to verify. I see he used my image of the 18650 cells. Naughty. 🫠 It takes a while but he is right they should be clear from end to end: https://diysolarforum.com/threads/48-cell-304-pallet-from-sun-fun-kits.72913/post-925563

I have tried multiple things as soon as you connect the heating pads it turns on and I see 7.6 amps going to the heating pads. Does anyone else have this issue?

I have something similiar but my issue is that the heating pads will not turn off! They keep running even without charging and are getting power from the battery itself.

I'm using this bms: https://jiabaidabms.com/products/jbd-smart-bms-3s-4s-100a-120a-150a-200a-lithium-lion-battery-pcb-with-uart-heating-function-series-connection and these heating pads...

This is sounded like some fairy tale the company is making up, you should look under the qr code. I have not seen this before and why hasn't this come up on any other cells before. Most of these companies with real grade A also give you a test report like 18650batterystore and sunfunkits, did...

That seems like a lot of craziness, I would just get the DIY sfk kit with the heat pads, I did something like this guy did: He used the same JK bms but you could run the bms from the switch. I have it on mine and its works flawlelessly add heating to anything.

The v5 kit or the v4 with the gen 2 switch so you can turn the active balancer on or off or set it to turn on when the battery is full. Also JBD can be hacked via bluetooth so being able to turn bluetooth off is a big safety feature. Sunfunkits are supposed to be sending me an upgrade kit so I...

If they stop trump I would be voting for him for sure. But I think the swamp already have there candidate, Niki Haley.

Renelogy: the study of Renogy :)

Shocking how fellow republicans are not acknowledging this guy. Sharp, self funded, not under the control of a super pac, and is a minority so the wokies already disarmed with the usual racial bs they use to get there point across.

Hey, I got 278ah from mine from 18650, but I was using in a 4 pack with a BMS so may be extra 1 AH if used with a standard tester. I made a battery using 4 cells...

Why is that you have Sun fun kits total cost including shipping but everyone else excluded shipping? If you apply the same cost on all other vendors vendors than 18650 would be $133/ kw including shipping batteryhookup would be $146/kw including shipping Sunfun would be $122/kw including...

I got an email from them as well. Shoot I'm asking around if anyone needs them in my area. These prices are falling off a cliff.

What about the 304 cells? 18650 has these in stock: https://www.18650batterystore.com/products/eve-lf304-grade-a-cells-3-2v-lifepo4-304ah-battery no waiting! If you are dead set on the 280K V3 then go with sun fun kits as 18650 does not have them in stock so you'll be waiting regardless. No...

5800 for 48 cells of 304 which are 1KWH cells: https://www.sunfunkits.com/productgroup/12/48-cell-eve-pallet-lf304-prismatic-lithium-certified-automotive-grade-32v?ProductID=127 $120.88 shipped/kw with the bus bars (non flex) and the round studs But its not 1 month it smore like 2+ months...

Well according to a spreadsheet 18650batterystore gave me I was supposed to get 295AH on a cell that tested only to 278AH. There spreadsheet did not have WH on them only AH. I just said the heck with it I have them now and its fine.

In case anyone is wondering the AH chat moved to this thread: https://diysolarforum.com/posts/950334/

They put both on the label now, I linked to my thread. I think the issue was with the 280K only meeting WH but not AH. My cells form 18650 were the same way, just shy of AH but meeting WH. So the issue of the 280K affects all vendors, now they have a 280K v3 that fixes this.

AHH, I was like what happened to the posts!

Watt-Hour is much more accurate way of measuring capacity. If you pass watt-hour you passed capacity test IMO, AH is nice but does not override WH I believe. from Sams thread: https://diysolarforum.com/threads/cell-price-drop.72837/post-950027 That link to quora post explains: Watt Hour is...

I purchased there cells based on this video: The guy showed the AH and WH, also at the time they were the cheapest cells I could find with test reports. So they do show the WH/3.2 is the AH. If WH / 3.2 is a valid way to get AH then why is this a point of contention? Either its right or wrong.

my cells both Watthours and Amhours on the label: https://diysolarforum.com/threads/48-cell-304-pallet-from-sun-fun-kits.72913/#post-925556 I don't think SFK is trying to be shady by including Wh. I also checked the QR code it did not have any signs of sanding.

This is quite interesting, I think this should be moved to the main forums, I have always thought the way to go was AH as well! Chat GPT is insane you can write whole term papers with it, using it to check for battery questions is genius :cool:
