12 cells Lipo Monitor and BalancerMonitor and balance up to twelve cells of lithium polyumer accu using a LTC6803-3 - Balance each cell with 300mA current. - SPI Interface is galvanically separated. Can be used with 3,3V and 5V. - High cell voltage accuracy made by the LTC6803-3 Double sided PCB was made bei PCBgogo in very good quality. Also the LTC6803-3 was orderd and fit on the PCB by PCBgogo. Very good job. Thanks. Marc Wapelhorst6809 0 Jul 25.2018, 18:36:46

High voltage gain boost converter based on voltage lifts techniquesHere are the photography of prototype. The conversion ratio of boost voltage with voltage lifts capability can boost up to 4 times higher than the traditional boost converter. It is simply added two more L and C resonant circuit plus additional diodes to control the current flows for achieving this circuit operation.5868 0 Jul 15.2018, 08:46:30
