Some vendors charge more, but they shipped me an extra cell with my next order. I hope they take care of you.thanks for the advice,
unfortunately Doncan is saying "you need to return the cell".
These were ordered from China, so it is more expensive to send this one back than to just order a new one.
I understand that they send me good cells its not their fault one arrived damaged, but it is not my fault either Lucky me.
This was the 48th cell I ordered from them.
They are talking to the shipping company now to see if they will assume some cost.
Lets see how this ends

There's actually pouches inside of the aluminum case, and the pouches (in the pictures and videos I have seen) aren't generally stuffed into the corners tightly, so there's a good chance that that cell is fine.
My son dropped a pack I had made, and it did way more damage to the corner, there's a flat spot now. It's still operational, and I couldn't find any difference in it when I tested it again. It appears to have only damaged the aluminum case, rather than the pouch inside.
I would check IR, capacity, then run it through a few hard charges and discharges and monitor for swelling. If you don't see any issues, I would personally use it.
It's been about a year, but they're in a very high draw situation, so I imagine that any problems probably would have been seen by now. I regularly pull 2-3c, surges up to 5c, out of the pack. They're also not 280s, or from the same manufacturer / distributor. You definitely right though, only time will tell.Doesn't always work out like that. You at the two year mark yet?
That's definitely an interesting thread. I'm not going to say that the damage wasn't a contributing factor to the failure, but it seemed like there was a lot going on with that pack and builder, other than just the dents. I do know that there are quite a few users on here that have packs with mild mechanical damage that are functioning just fine though. For what it's worth, from what I remember from seeing the cells disassembled, there was more free space on the bottom between the roll, then there was on the top where it was connected to the terminals.280AH EVE CELL LASTED ONLY TWO YEARS
Hello All, I was one of the early purchasers of the 280ah EVE cells from Amy and one of the cells has malfunctioned already. Do these things have a warranty? How can I reach Amy now days? Is she the one in Houston now? About the bad cell, it has swollen tremendously and will not take a...diysolarforum.com
big oof, isn't the max like 1C continuous, 3C peak with these cells?I regularly pull 2-3c, surges up to 5c, out of the pack.
Different cells. They are rated to 3c.big oof, isn't the max like 1C continuous, 3C peak with these cells?
Care to share the datasheet?Different cells. They are rated to 3c.
I have both the Navitas and TopBand versions, the TopBand ones I have are matched EV grade.Care to share the datasheet?
I have some in my son's power wheels, it draws 50+ amps and hauls ass. Endless torque compared to the old 9ah SLA too.I love my wee Navitas cells! Literally sitting there doing nothing on the JBD... just had to have those little green cells!

I have another pack that I plan on hooking up to an old UPS, 25ah would run my modem and router forever. I still need work on an isolated charging system for it though.
