Flytouch/epad battery longevity?

i have found suitable one (7.4 v)Lithium Li-Ion 18650 7.4V 2200mAh Battery Pack L18650-2200-2but not sure it will fit inside - height is 0.7 inch

If you search eBay for "eken battery" you'll find 1800mAh batteries that will fit for $15 - $20 shipped (and may even be what we already have).Does anyone know if we really have 2400mAh ones inside?

on photo in this thread http://www.slatedroid.com/flytouch-epad/4277-actual-battery-capacity.htmltwo batteries 3.7 serial connected and total voltage 7.4 v and capacity is 2400mah.so i think if put inside two batteries 7.4v with capacity 2200mah connected parrallel, we've got total voltage 7.4 v and capacity 4400mah or this one http://cgi.ebay.com/7-4-V-4200MAH-3...0501480133?pt=Radio_Control_Parts_Accessorieswill prolongue work time to X2i don't teardown my flytouch cause my gentouch is on the way to me and i want sell my flytouch

With the firmware v1.6 build 1.9_88 the battery life increased to over 3 hrs almost 4 hrs. Of course I have some tweaks running Memory Lite (Kill App Rouge, Advance Task Killer Pro (Aggressive Mode)
