I am in the process of building a custom board running an AT32AP7002 with LCD and all.. The unit will be battery-operated using a single cell Li-Poly battery. I already have designed most of the power supply, but some of the circuit needs to be custom-tailored to the battery, and the battery is proving a b***h to source...
What I am looking for is reasonably-priced UL-listed LiPo cells, 3.7v, >2600maH. Physical size is important, cell should be a flat pad, no more than about 5mm thick. The battery will fit under my board in a 4.3in TFT enclosure..
Do any of you fine gents ever had to source some li-poly cells and if so who did you end up buying from? I am looking at 1000 units orders..
