I was all excited about getting my four 280Ah 3.2V prismatic aluminum cells today. Got FedEx text at 5:30am this morning that they were on vehicle for delivery!!! Then an hour ago, I get another text that delivery is rescheduled for tomorrow. Certainly need to exercise extreme patience during...

Nice...that will provide you a sizable reserve!!!

Price to door was $583 for four 280Ah. Will be using the Chargery BMS8T. Which are you getting?

I ordered my four 280Ah cells from Xuba (with Amy's support), on 16 Mar. As of this morning, those cells made the trip across the Pacific and arrived in Carson, CA. They are schedule to arrive at my residence in Pennsylvania by Mar 30. That's a VERY quick two weeks door-to-door. Keeping my...

Thanks Steve. As a noob, this is why I almost found out the hard way to run my thoughts through this forum. Quick question, what is difference between common port and separate port? And which is appropriate for my 4 cell configuration?

I asked Amy to toss in the Buss Bars and Bolts. Her response, "I already put them in the box"!!!! Again thanks Steve_S for paving the road! Hats off to Xuba and Amy!

Hello folks, Well the four 280AH cells are ordered and shipped. So while waiting, I figure its not to soon to now investigate and order the BMS and inverter. I'm thinking 2000 watt constant/4000 watt peak pure sine wave inverter. So doing the math, 2000w/12v=166Amp. This is my first build...

What about the one cell being 3.34x?

Thanks Steve for "paving the road"!

Thanks for your feedback. So is the voltage being higher not a good thing? If so, what is the consequence?

WOW...I am floored by the exceptional customer service so for from Xuba. I asked just a couple ours ago if my cell had shipped. Amy promptly responded and stated that "your order was sent out yesterday" with a few pictures of my four cells...get this with a tag that had my name hand written on...

Yes...agree. I was also apprised of same by Amy at Xuba. She also offered that shipping costs are DOUBLING just from yesterday.

BRAKES ON!!! THANK YOU Steve and GhostWriter!!!! Redirected myself to the Alibaba site recommended by Steve...again THANK YOU!!! Just ordered four of the 280ah cells from xuba (apparently back in stock). They do whack you on shipping though. $330 for cells and $282 for shipping...$582...

I have tried Visa and Master Card. Same issues.

Here is one vendor: https://www.aliexpress.com/item/33035453389.html?spm=a2g0s.9042311.0.0.5b634c4dgiV0TR And here is a second (these have to be Grade B given the price): https://www.aliexpress.com/item/4000518156949.html?spm=a2g0s.9042311.0.0.5b634c4dgiV0TR Both vendors failed. First vendor...

I wish that did it. I did contact the vendor, and they responded "check your email". I did check my email, and that is where they wanted me to submit pics of my picture ID and Credit Card. Why do they need that????? I will not send that. I have never been requested to that for anything in...

Ahhhh...KISS principle and wrinkles in same paragraph!!! What's a sane man to do? Seriously, all good stuff...thanks.

Folks...who else is having this problem. I have been trying to buy 4 prismatic cell for the last five days...about $650. AliExpress will not accept my payment! What the heck...they don't want my money? I make other purchases...lower dollar value without issue! Same credit card, same...

Appreciate comments from both of you. Yes, when I was working in the defense industry, we did ALL we could to preclude SPFs. At the same token, the technology has advanced and minimized the risks of failure. Thanks for both posts.

Ahhh....more power! MORE POWER!!!

Thank you. I was thinking the same as far as fewer cells equals less components to go wrong.

Hi Folks, My goal is a single 200AH capacity LiFePO4 4-cell battery pack. I am seeing 200AH prismatic cells on AliExpress at reasonable prices. Is there a downside to using single 4-cell 200AH battery pack, rather putting two 100AH 4-cell packs in parallel? Specs are comparable between 100AH...

Hello folks, Just downloaded the subject app for the DYKB 4s 100A BMS. When trying to install, its looking for access to 1) read my phone status and identity, 2) modify or delete the contents of the SD card, and 3) wants my PRECISE location. Does this concern anyone else besides me???!!! Has...
