My experience, so far, has been very unsatisfactory. No assembly instructions are given and it was unclear how the battery pack is to be assembled. The most likely possibilities being 2 packs of 4 cells in parallel giving 7.4V or 8 cells in parallel. I have tried both options with charged cells and the display shows all values with either option, A second unit behaves in the same way. No explanation of normal operation has been received and the push button switch merely activates the display. If I receive no help, I will return these as unfit for purpose.
