absolute garbage i've ordered 50pcs 6 of them where broken ( 0V From the begining) I've mounted the cels in 3 drilling machines battery (A bosch, a milwake and a makita - ni-cd battery). None of them works more than 5 min before recharging. Monkey waste...
batteries advertised as 1.2v, but cells reach at most 1.15v, also advertised as 3000mah capacity, but testing showed much lower numbers (800-1500)
