I'm not following... check if they are all lasered off like the one in the photo? Still not sure whether these are just B's pretending to be A's, or 2yr old cells that have been worked and re-labeled as July 2022... :/
So what do you all think? Do these cells look new and just "grade b" cells from EVE and re-lasered to remove the "B", or used and re-lasered QR codes to hide the original dates?
Ok, it looks like there was probably some lasering going on here... large area around the QR has a different shine.
These were not sold to me as "Certified Automotive" but as "They are all brand new and solar storage cells." So I'm thinking they are (hopefully) new but didn't meet the...
Hi, first off I'm pretty new to this, so please be nice. :)
Last year, I purchased (from Jenny Wu @ Docan) a set of 8 LF50K cells for a small 50Ah 24v motorized kayak battery build, and the cells were VERY flat. Battery works great.
I just purchased another set of 8 LF304K cells from the...
Thanks, I’m just googled and looks similar but all the ones online have blue shrink wrap. Why wouldn’t mine have that?
Looks like some of that yellow board between bms and the cell, but yeah, not much.
I opened up a Zooms 12v 50Ah battery expecting for it to look more like the same size AmpereTime that Will Prowse tore down on YouTube, but it looks different.
BMS looks as expected, wired up with 8AWG tinned copper positive and dual 12AWG negatives. High temp switch mounted with just a...
I just opened up a Zooms 50Ah this am, and didn’t do a full teardown, but it looks really nice inside. I wish the case they built these smaller batteries in was more compact though. It’s way bigger, especially taller than the contents.
I just tried cutting off the top of a Zooms 50Ah box to fit two batteries into a Apache 3800 case. Hand saw made quick work of it. If I could find a flat top to put onto the bottom of the box, that doesn’t stick up an extra inch like the original, that would be amazing. Anyone know of one? :)
