Hi Bobby,
The standard BatShare has two standard connectors in and two standard connectors out. This is because each input can handle 3 amps continuous, limited by the R/C connector. The two output connectors allow you to output 6 amps when both are used. The BatShareHD has one output becuase it consists of 18ga wire and a Deans Ultra plug. The output can really handle more than the inputs. We also make a BatShareUltra with 18ga wire and Deans Ultra plugs on both the input and output. We do not make any BatShares with multiple Deans outputs as they are not needed. Please let me know if I did not answer your question correctly.
