What about these?TP0730-3SJ.
Thunder Power "Super Dynamic Power" LiPo Electric Flight Pack
730 mAh, 3 cell (11.1V), JST connector
Rating: 10C-12C Continuous Discharge
Dimensions (wt): 34mm x 50mm x 14mm (45gm)
Is it just that simple, for example, 2 of these packs in Parallel would supply Double the mAh, double the Discharge Rate, and maintain the 11.1 Voltage?
For me cost is not the issue! I want a setup that is light enough, and will not get to hot, while delivering plenty of power and duration! That does not seem like to much to ask! hehehe ;-)
