I think you are over-complicating this. You can parallel Lithium Ion cells as long as you make sure that they are well matched (i.e., same exact type and perhaps from the same manufacturing batch), are always kept at roughly the same temperature while connected to each other, and that they are charged to the same level before you first connect them. After this, they will track each other very well and there will not be significant current between them. Sean On Sat, Jun 18, 2011 at 4:25 PM, V G wrote: > So...
