i have a friend who wants to make a battery pack to sell but we are not sure on the needed specs for the battery.

like how many Volts/Amps would be needed for pineapple with 3G dongle, or Alpha backpack.

im guessing 9v, 2a would work, anyone else have any thoughts?

+ average battery usage time would be useful

Careful when it comes to making and selling battery packs. There are a bunch of certifications necessary and homemade units usually don't conform. Personally I'm a fan of 18650s, which come in 2000-3000 mAh varieties at 3.7v. Four of these in a 2P2S config does an amazing job. Just don't over volt or draw too much. Nobody likes exploding batteries =/
