Again for you. Here’s the only mention of bringing cells from 1v. It’s a quote you posted of mine from years ago
The irony as u all rage again that I said you can bring cells back from 1v. You can! It’s in many data sheets. I think every Samsung I’ve seen. Also Sony and Sanyo and Panasonic all have cells with data sheets saying so
Watch u folks rage that somehow I’m wrong or dangerous again anyway. And I didn’t even bring it up am an responding to insults and others starting
So you are admitting you’re the one who brought it up again first? 3 days of extra blood pressure and you getting all mad and you don’t want to admit that you started it and did this to yourself 
Again for u for the third time:
It’s ironic someone is asking about charging low voltage cells who before was one of those raging it’s too dangerous. That’s irony. That’s not me being insulting. YOU posted the CORRECT statement actually that u can while trying to insult me. If u can’t see the irony… oo well
Funny indeed. Me saying the word irony did it. Sure. And u quoting me stating u can recharge from 1v from literally years ago while mocking… you were just responding to the word irony. Got it.
@xsynatic are you able to move posts still? Like everything from this post down gets moved to the bin?

Ay you finally admitted it. Yeah @xsynatic bin this please it’s covered in pigeon shit

A bit of an off topic question. I ordered a Tynee Explorer Pro. They “upgraded” me to a GD version because there was some delay with customs strike. Doesn’t really meter. The Board arrived yesterday with a fully charged battery! Like full on 97%, 57 V (It is 14s4p baterry with samsung 50s) How bas is this …how long can a battery be stored at full charge and when does the degradation of the cells start to happen? I have already wirten some furios e-mails but haven’t gotten any response yet. My DIY has been at full charge for a few days, but this could have been siting in a warehouse somewhere for months as far as I know.
What do you guys think. Is the “damage” negligible or what?

I’d be suspicious the board was a return, and why it was returned.
I don’t know about damage from storing at full charge.
I think I recall @Battery_Mooch capacity testing cells stored at full charge for a period of time and they did not lose much capacity.
Can’t remember how long they were stored, and how much capacity they lost though, or if that data is Patron only.

Just based off of my reading and limited knowledge here so know this isn’t expert advice. It’s, imho, not about storing the battery at full charge for a little while but more about doing so all the time. If you want to get the most useful life from it STRIVE to stay out of the top and bottom of the charge as much as possible.
When the cell is at full charge it is in its most unstable state. It wants to discharge as hard as it can. All the electrical potential is maxed out and all the chemical reactions are looking for anything to do. Any side reactions are more likely and easier for the cell to do and it’s just harder on everything. It’s not bad as much as it is going to age itself but you aren’t getting all that fun work out of it in the process. This aging isn’t abnormal but it is more than if stored at a lower potential.
If you can store the battery for most of its useful life at a lower charge state. It will help to, over many years of use, add up to more useful life and more cycles. One incident of storage at a high potential isn’t ideal but it’s also not the big picture or going to make a noticeable difference in the cell performance. You want to try to keep it at a lower charge state for the majority of its life because those not nearly noticeable differences will add up over time to become a noticeable difference.
TLDR the pack is likely still in great condition but @SternWake ‘s suspicion of it being a return likely the cause. Give a thorough once over and rest easy

do a capacity test.
That thing looks like fun but no way will it handle the voltage. No reference discharge to compare it to either as it going to introduce its own variables. Might be fun to just take a cell and keep it on a smart charger for a couple years and compare it to a properly stored one but i haven’t got time for that 
still need to follow through on spec sheet wiki
IMO, yea, you probably don’t have to worry assuming everything else is okay.
The degradation starts the moment the cell is assembled and continues 24/7. It degrades faster at higher voltages in some ways and at very low voltage in other ways. Basically, these cells love being around 30%-50% charge.
Having said that, they won’t get damaged after a few weeks at full charge. Perhaps a bit of extra aging of the cells versus being held at half charge but not noticeable but not for this length of time. Especially since the pack wasn’t being constantly topped off or held up at the full charge voltage (which QUICKLY ages a cell).
As others have mentioned, I wouldn’t worry about damage from that full charge. I would definitely want an explanation for why you received a pack at full charge at all. It’s illegal to ship that way and it being a return is pretty high on my list of possibilities.
The other possibility is that this company is just irresponsible and ships fully charged so they don’t have to listen to their customers whine about having to wait (while charging) to use their new board.

I suspected something like a return or maybe some warehous workers taking the board for a spin

Thanks to everyone for the replies, I fell much better now. But I’m still pised at Tynee.

I hope y’all would instantly realize this if you saw this cell for sale but just in case, this is a fake. Moli does not make an “INR-21700-50PL. Check www.molicel.com for more info.
