Hi I have what seems to be a untractable problem On a racing motorcycle I am using a total loss ingition/datalogging and water pump system. To power this I am using a 5000Ma 30C LiPo battery (used because of it light weight and small size). The measured battery output is 15.2 Volts. Both the ignition and datalogger are fine at this voltage as their parameters are 8-16VDC, however the control system for the waterpump is specified 12-13.5VDC. Sure enough when I connect this into the circuit the conroller has all sorts of issues.. Do you guys know of an elegant way to reduce the input voltage to an acceptable level? I have though of using a couple of diodes in series, but to be honest I dont know which ones to buy! Any help would be greatfully recieved.
