Product received without a problem. I use Godox V860 with my D7100. I tested both OK accumulators. The voltage for both very good. The battery comes with flash come from the 'new' production - "Grepow". Very good quality of pictures with the flash: direct, indirect, Master / Slave. I tested also radio control (manual only) for the flash - ok. Small consumption for the remote but nothing serious. In future I would need to Godox V860 / V850.
