Calling SOFIRN: detailed data on your 5000mAh 21700 battery needed

Lishen LR2170SD

Thanks, but I think you may have missed this a little further up in the other thread I pointed to above:

@Lux-Perpetua

I was given the datasheet for LR2170SD (03BCEA5), so yes, it should be that exact model.

@PiercingTheDarkness

I don’t think Sofirn use this same battery anymore. The one they’re using now seems to much, much better.

And in fact some of the specs in the (incomplete) list on Sofirn’s product page disagrees with the LR2170SD datasheet. And the battery’s negative terminal shows a circular vent in Mooch’s review/test post:

which definitely does not exist in the battery I’ve received from Sofirn:

So it seems that, at some time in the past, Sofirn indeed rewrapped the LR2170SD, but apparently not anymore.

Please @Barry0892 and @Sofirn, can you clarify this for us? TIA!
