Halogen bulbs are made in general for 6V, 12V, 24V. To run the lamps on 120v AC a transformer is needed. A rectification is not needed because the bulbs work with AC and DC. The halogen lamp is an advanced form of incandescent lamp.
Using too low a voltage will produce little current and too high a voltage will produce high current and overheating of the filament Sent from my iPad > On Nov 4, 2015, at 6:39 PM, Mike Beem via EV <[email protected]> wrote: > > I have been trying to re-balance my 4 year old 100Ah CALB pack with > mini-BMS, identifying the highest SOC cells by watching for the red LED's > to light up on the mini-BMS boards on the individual cells.
