TangsFire TS18350 1500mAh (White)



Official specifications:

• Capacity: 1500mAh
• Voltage 3.7V

Some cheap ebay cells.










The result is not that surprising, one cell is a fairly decent high current cell, the other a high capacity cell and none of them are near the rated capacity.



I forgot to attach the temp sensor on the A cell.



















Conclusion

Either cell is fairly decent, but they are definitly not the same and do not live up to the specifications.
I will rate them as bad cells.

не соглашусь. вполне приличная ёмкость для 18350. на обёртке просто соврали
разница в ёмкости при разряде токами 0,1 ампер и 3 ампера - очень небольшая в отличии от других TangsFire
если не брать в расчёт очень высокие токи (больше 3 ампер), то аккумулятор показывает неплохое качество

You are missing the point, two different cells mean they probably take any 18350 sized cell and put their wrapper on. This time it was two half decent cell, the next cell they use may be a very bad cell.

HKJ, это как игра в покер. главное - угадать, когда производитель (а может продавец) блефует
