Just for the sake of sanity I'd like to have some hard data indicating this is an issue since I've never seen this brought up. Those tests showing the cells seriously overcharged or thrown in a flaming pit you don't see gas igniting above the LiFePO4 cells. Even if hydrogen were produced that would indicate something is being broken down in the cell causing permanent damage and a good BMS would prevent that (over temp). Seriously curious if this is an issue since I think many people have these in a sealed container.My RV repair and info guru advised that, while manufacturers claim there isn’t any gas given off, his mentor/instructors showed a closed box with lithium batteries in, and lit a match- Flash of hydrogen burning.
I don’t feel like being a statistic.
- I also wanted to apply it to setting a fan up for other timed purposes, so it will cover a few bases to know how to set up a 12v fan on a timer function.
My guru said he didn’t want me to be the cautionary tale he tells all future customers as to why to make sure and vent.Just for the sake of sanity I'd like to have some hard data indicating this is an issue since I've never seen this brought up.

I question if they actually have any engineers. The only engineer I would trust that says a damaged cell is safe to use would be an engineer who works for the manufacturer.Here is their reply:
I'm sorry to hear this news. Our engineers said that this Dent does not affect the use of the battery. You should first test the internal resistance, voltage and capacity of the battery.
We are willing to refund you $20 as compensation, and we will pay more attention to the packaging and transportation process in the future.
I would not use the term "Guru" for that fellow, he still thinks in Lead Acid terms. Likely does not even know the vast differences between Lithium Chemistries and THAT IS OK as it's a lot of knowledge to have and that is usually for serious Hobbyists & Pro's who do this for a living, not to forget those of us who are Off-Gridders (tend to be hardcore ;-) ).My guru said he didn’t want me to be the cautionary tale he tells all future customers
Based on how I think of the term guru, its a term / way of thinking I would avoid in general, at least for technical topics. In my eyes it gives a somewhat false/inflated sense of security and confidence in one persons understanding.I would not use the term "Guru" for that fellow, he still thinks in Lead Acid terms.
What would happen if you tried to order one cell? Would it be free? Unfortunately you would have to pay for shipping. Too bad they used plural when they said batteries. And they are denying they shipped it that way. You could dispute it with TA and/or your CC company.XUBA - "Sorry we do not make much profit on the batteries, we will give a free battery NEXT time you buy batteries from us".
They are making it sound like they do NOT have shipping insurance on the items, WT$.
I asked them for replacement or money back attributable to 1 cell.
What should I do [other than trying out lace under clothing]
Just to chip in here. Supposedly my order from Xuba was shipped on 12/16/2020. I haven't seen any shipping update. I messaged the seller and they said the ship was damaged coming over seas to the US and apparently in Mexico getting repaired and should be done in "March". Needless to say I definitely put a refund request in.
Xuba claims the shipment was on the ship with the 750 containers lost, but says that the cells are still on board. Of course we won’t know for sure until they unload.Why do you put a refund request in? I don't think its fair to blame Xuba (or any other seller) for issues with a specific boat. This does occur sometimes unfortunately.
This is also one of the risk when buying directly from China. It doesn't affect you moneywise, it's insured and you will get the batteries eventually, but it does add delays. You have taken this risk, and in return, a lower price.
Luckely, the majority of the shipments goes without any problems. Recently, the ONE Apus disaster hit, and was affecting some of the members shipments here as well.
Currently, there are 2 boats affected by severe weather in the Pacific Ocean.
The Maersk Essen, lost 750 containers, repaired in Mexico (I assume this one is having your shipment). New ETA for arrival in LA is now set to march 4th. However, LA port has been queued up, not sure if they can bypass this to make up for the delays (They are negotiating with port authorities afaik)
Second is the Maersk Eindhoven, lost 260 containers, 65 damaged, currently heading towards Yokohama (JP) for repair, LA port arrival unknown yet.
Damage at the Maersk Essen (Now from Mexico towards LA after repairs)
I only hope your cells are still onboard. Otherwise they need to be resend all the way from CN. But the sender probably only knows this after the ship has been unloaded, so untill than they don’t know either which containers are affected. You could be lucky with only delays, but be unlucky if you're cells are now somewhere on the bottom of the ocean and it will take some more weeks to unload and find out your shipment was affected.
A little patience. Amy went to bed 1/2 hour ago (00:20 hrs her time). Big Time Difference, for me in EST it's 12 hours.
Customs and shipper's are all backlogged and working overtime with reduced staffing, this of course affects all shipments and deliveries too.
Methods of shipment are also all affected too to varying degrees as well.
Couriers & Post Offices worldwide are basically stating they are carrying Christmas Level Packages but without the usual seasonal casual employees to help with the load of parcels being processed which is also putting strain on everything.
Have the cells give you any problems since you heard the liquid move around? I just got a set of cells and I'm not sure if the liquid movement is normal. I also got my cells with 2.8volts so I'm scare there is a real problem with them.Balancing 96 cells...
Now i also hear the liquid flowing inside the cells when you rotate them. Kinda freaky to be honest
