I own the Robbe-loaders POWER PEAK B7 EQ-BID 12 / 230V (POWER PEAK B7 EQ-BID 12/230), what the board fits perfectly. It fits on Graupner and HiTec-loader. The Balancer board is suitable for all standard battery connector types, and up to 6 cells and clearly designed in black and white area (depending on cell count) with clear writing. In addition, there is a total of super processed and completely isolated. Other boards consist only of the board with a foam under bonded. Everything is in a reasonable plastic housing and thus properly sealed at least below. I'm very satisfied and not hesitate to recommend.
