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...

Second time is a charm. After the horror story of being defrauded out of $253 last order (finally getting all of it back after 2 months of fighting with first vendor AliExpress is getting money back to me), this vendor delivered in spades. Three 100 watt semi-flexible panels were delivered...

Once Again...Hats off to Xuba and Amy!!! I have been having an issue with one of the four 280AH LFP cells from my recent order I placed 19 March with Xuba. At the low end of the power band, below ~3.2V one of the four cells would discharge MUCH faster than the other three cells. Conversely...

Has anyone run across the specs for the LiitiKala 100AH LFP cells being sold on AliX? I have looked and googled attempting to get the data, and have not been successful. If so, could you please post, or direct me to where I can obtain? I bought four cells back in January, and am expecting...

Folks, I need some help understanding "maximum series fuse rating", and how this rating applies to my solar setup. I attached an excerpt from the spec sheet for my panels below. I will be putting three of these panels in series 3S1P (for now...may expand to 3S2P) going into an EPever Tracer...

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...

I am seeing these 100AH LFP prismatic cells on AliExpress at $160...shipped to USA. This seems to be the lowest price I found. Has anyone found a lower price? Does anyone have any experience with these cells? Grade A or B??? Thanks for any feedback, Mike 4pcs 3.2V 100Ah LiFePO4 battery...

Anyone have any experience with these panels? If favorable, I plan to put three of these on the top of my pickup bed cap with suction cups to use with my Xuba 280AH LFP system. Price seems reasonable and shipping time is not stupid long. Of course this will be a portable system attached to...

Hello folks. Looking to the Braintrust for some help. I recently bought four used panels off FB Marketplace. They are 305w LG panels...VOC 40.0v, ISC 10.1a, Vmpp 32.1v, and Immp 9.52v. I think I got a great price ($80/panel) on them as they all tested very close to the specs. Now I need to...

Hello folks...first a little background. I was using the Chargery 8T BMS on a 4S EVE 280 AH LFP pack. I ran into one issue after another, until finally it just simply wouldn't turn on. BUT please I don't want this thread to be a about who has had success or issues with the Chargery. I am...

Good morning folks. Let's hope all are continuing to be COVID-19 responsible. I just got an unsolicited quote for Lead Crystal Battery. I am new to this and am looking for feedback. Quickly googling and watching a couple youtube vids, I see the technology has been around since WWII, but...

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...

Okay it happened. One of the M6 holes stripped out on my four EVE 280Ah cells. Please help. I was going to simply retap for an M8 hole. But my taps lowest/beginning cutting edges will not cut thread deep enough until I get down 3/8" or so, which will puncture into the "chemical" inside the...

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...

Okay folks. I am putting all the pieces together finally. Been taking baby steps as I am a novice at best, and learning tons with each step and the continued help here of the forum members. So it's time to toss my drawing out here for review, and a sanity check. But first here are a few...

Hello all, 50% State-of-Charge is the recommendation for storing LFP cells from all I've read. I have a few questions to help me understand that recommendation better: 1. In looking at the charge profile on the spec sheet, it appears the 50% SOC mark is about 3.28V per cell, or 13.12V for...

I was hoping to report that I scored a good value on a Suredom 2000w/4000w Pure Sine Wave Inverter at $159. NOPE!!! I should have know better with a High Temp Shut Off Spec of 75C...that's HOT!!! But I simply didn't know better being a noobie. So after testing at 1700 watts constant load...

Hello folks, In reading all the documentation on the various SCCs, the documentation is consistently saying to have battery connected to SCC before attaching solar panel(s). However if my memory serves me correctly, I have seen videos and posts that conflicts with that documentation...

Hi Folks, My "portable" Solar system is in final assembly. Just need one more very critical component...the Solar Charge Controller. The options are many, and my experience is very limited. So, I am asking for recommendations. A few details first. The battery pack is the Xuba 280 12V LFP...

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...
