For a batterybackup for a burglar alarm I would like to use supercaps. The alarm runs 12 V and the supercaps are around 5 V max. I would like to ask if some one knows a simple way to konnect 2 or 3 supercaps so that they get charged (each only with nominal V) by the powersupply from the alarm (12 V), and so that if the power fails, they are connected in serie and give the combined V to the alarm?
