HiTec RDX1 charger with ChargeMaster software, Another SkyRC imax B6 B6AC clone Lipo LiIo

I bought this charger to charge some LiIo 18650 recycled cells. The button layout looks like you typical SkyRC imax knock off. The charger looks great. I like the test bench design. I noticed that the Chargemaster software is identical to SkyRC software. The PCB layout is complete different the the B6AC.
