I have 2. One packed up - no charging and later no power out. They eventually sent a replacement which arrived today, but sadly the PCMaster is showing error, error error
![Frown :( :(](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
. Done all the pre checks 1st of course and i spotted the Resistance was totally wrong.
Hope on hope i connected and tried all ways to boot it up - it eventually showed the cell voltages, but then that disappeared.
Tried reprogramming the voltages to the correct settings but no joy either. They are a pain in the neck when not firing up.
Have started another "Refund please". I used AliExpress. Will's fav store ???
I do have one that worked straight out of the box, easy peasy, and has not let me down so far after 3 month.
