After reading OSUengineer's thread about how he created an iPhone 4 battery with double the life by wiring two batteries in parallel (http://forums.macrumors.com/showthread.php?t=1358820&highlight=double+battery), I decided that I wanted to try this myself. After opening up an iPhone 4 battery to expose the point where the connector is soldered to the battery, I concluded that all OSUengineer did was remove the connector from the second battery and then connect the corresponding nodes on the second battery (without the connector) to the nodes on the first battery (with the connector) using wires. Can anyone confirm that this is what he did and/or that this will work? I'm PRETTY sure (anyone get that SNL reference? ) that this would work but I am looking for an opinion from someone who knows a little bit more about this than I do. By the way, I am starting a new thread for this because the original thread started by OSUengineer seems to have gone dead as I am getting no replies on my posts there and the OP hasn't posted on there in a long time. Anyways, what do you guys think? Would this work? I added a picture of an iPhone 4 battery I took apart where the connector is soldered to the battery.
