4PCS Samsung INR18650-30Q 3000mAh Button Top from Banggood $20
4PCS LG MJ1 18650 Battery Genuine & Tested - 10A 3500mAh from LiIon Wholesale $20
These have been through fewer than 5 cycles, reputable dealers, tested with an Opus charger. The shipping labels on the LG’s just rub off, hence the smudges. Cases pictured are included.
Bought them only for trip to a relatives farm last year- lights (TN42 and Olight X7) are sold and I no longer need so many cells.
They are in fine condition, <5 cycles = good as new. tested with the opus. If they weren’t I wouldnt sell them.
Purchased new 9 months ago- not a huge surprise if they were manufactured a year before that- as we know, these unprotected cells with added button tops get to consumers from grey market sources, samsung and lg aren’t trying to put unprotected 18650s into flashlights
But, # of cycles and avoiding heat exposure/ over discharge / overcharge matters most, and as mentioned i bought from LiIon Wholesale and Banggood, stored these properly, fewer than 5 light charge cycles, and didn’t overdischarge.
