good power source for Power Flashlights

Among the 3400 mA / h batteries in 18650 format of this battery is not at the forefront of capacity and measurable under the manufacturer's instructions. Here I would want from NiteCore the same honesty as with their flashlights very positive is the case. Comparable 3400 mAh batteries eg Panasonic, Eagletac or Keep power supply as significantly more power. Nevertheless, this is a good and reliable battery and in particular the significant increase in positive ensures a good electrical contact in flashlights with mechanical reverse voltage protection.
