If you were only wanting to ride at 12 mph to 16mph max speed then a 52 volt 8 amp hour pack would do .
When you want to go over 17 mph your battery usage increases , at 25 mph then you are really wanting to have a pack of 12 amp hours or more.
If Luna is out of stock on what you want, there is also Em3ev.com , there are other places to buy batteries.
However the faster the speed you go the better the quality of battery you will need to have, to get your money's worth of usage.
Keep in mind it is better to have 20% -30% of battery capacity left on your pack after the longest of any of your rides , in order to have your battery pack have its full amount of life cycles .

commuting 10 miles per day max. Would like to be able to get up to 25mph.
Luna shark packs are out of stock right now. Thank you for any input and help. I'm still doing a lot of learning and reading, it's a little overwhelming and I wanna be able to ride!
