Gaining access to 12 voltsYou can see, the battery under the DVD drive I had it lying around for ages and was originally purchased as an 'external laptop UPS', however I lost all of the connectors and had to crack it open to access the 12v circuit. I would not recommend this, but rather keep all the adapters and just wire it in parallel to your charging circuit.
