I am contemplating setting up a SSC P7 Direct Drive A123 light and wanted to try and glean some information before the build. On my other P7 builds I have always used the 8 x 7135 linear driver solutions and been satisfied with the results. I have searched the CPF and found treads on DDing the P7 on single Emoli and 3 to 4 NiMH battery sources but nothing specific on driving the P7 on a single 3.3 volt A123 cell. Anyone ever try this? Would a P7 with a lower Vf be desirable? For example would a DSWOI be better than a DSWOJ because of the lower voltage of the A123 cell? The goal would be to run the P7 at up to 2.8 amps to maximize output and minimize heat yet still have the inherently safe chemistry of the LiFePO4 cell.:candle:
