It seems to be going that way .... but that other thread hasn't really posted much evidence of wide spread Lishen leaking cells as their intro seemed to indicate.
Bad cells and poor Qc on the part of both lishen and BB. I mean seriously...how do leaky cells get passed both? perhaps I know how they got out of China.....they’ll sell anything. I would expect BB should recognize this, too.
No, I am sure they are not. But to me, the pressure relief valve should be on the top. I decided before anyone complained about leaking cells that I would keep mine upright. Likely that the electrolyte coverage is also better in that position.
Sure and they use cylindrical cells. Either way, these cells should not be leaking. I am looking forward to an update in the other thread regarding this.
I have heard people say that their 272AH cells have corrosion on the vent covers lately. I just dismissed it as a smudge or something, perhaps I misjudged.
I have wondered about that too. Maybe being stored in a high humidity environment caused the corrosion. It wasn't bad. But I don't know or can't recall anyone with EVE cells reporting corrosion in that area. I don't know what material is used in any of the vent covers. Probably aluminum?
Certainly is a mystery. If a Lishen defect, then its possible (this is pure speculation) that the defect isn’t making itself noticeable until a certain event, for instance a few charge cycles or until perhaps the terminals or terminal areas are stressed enough or in just the right way.
I asked BB for permission to break seal & inspect. They said yes, open and look, no disassembly allowed. I didn't see any value to do so at the time because wills was the only one. I am rethinking that now I have read this thread. "Note" I have been using mine on its back with cells vertical since reading about wills issue.
Please reply back and let me know if you have issues. I will be sure do to the same. Spent too much money on these things not to monitor them.
Pic of my box. Shipping label on bottom? No arrows
Agreed about volt meter. mine do the same. I believe the meter is wired on the wrong side of switch. And yes button in= power on, button out= power off, independent of each outer
I suspect they are rather heavy, and rough handling during shipping must break a seal that should obviously be a bit stronger. I doubt that BB is knowingly installing and shipping leaking cells, and are pretty unhappy about it.
Yes, unfortunately any comment he makes opens him up to legal liability problems for something that *I think* is not really his fault, and couldn't really be foreseen. Certainly I wouldn't expect the cells to leak, the manufacturer of the cells says the orientation is perfectly acceptable, etc.
Hmm, I would not call the thread hostile. Justifiably skeptical perhaps. There is the matter of living down the white grease claim. I can understand some discomfort there. As things stand I will forevermore associate Big Battery with "white grease eats your battery".
