The big Ebay refund day - finally got my Opus BT-C3100 v2.2 - fake, fake and fake. (batteries from Ebay)

i am the new owner of 2x lii-500 from Ali Express (~$24)

and would like to confer with other owners of the lii-500

how low does your lii-500 discharge before charging and to how high

i need more time with mine
i see 3.50v on the discharge
and 4.21v - 4.22v for the full charge

i started a mini review of the lii-500

BTW once i bought x…FIRE cells (got my money back) and i guess they are ~1000mAh
