I don't know how all this is hooked up, but if there is a secondary per cell, then there must be a diode in there too. If you run the transformer in flyback mode, then the lower voltage cells will suck up more of the energy per pulse, but this isn't going to be a very hard limit. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
