If you do, have you ever just been stranded because the charge didn't last for as long as you thought??? That would suck nuts man. but it is one of my main concerns of getting an electric motor vehicular device. I want to commute to school n stuff with it so it'll be sitting there not charging for hours at a time, possibly a day if I'm partying and electric things can loose its charge a tiny bit when it's just chillin there not full right?
I don't want to be riding home and then fuckin BAM it dies. right in the middle of the road. so i look like a double tard now because I'm supposed to be saving money and knowing my vehicle, but I have to call my friend and he's laughing all like "told you so man, you look like a panzy AND it doesn't even run you back to the house" which would probably be like a mile away. Freakin Jerk.
Anything like this happen to you all? anybody? if so please let me know, I don't want to shell out my life savings to save my Planet when I'm just going to get ripped by a bloody drained battery.

get one with a charge gauge, then you wont be caught unawares. For a day you dont have to worry bout batteries loosing charge due to inactivity, batteries i got for my project self discharge 2% per year or something ridiculously small :D

I've had several near misses in 2500 miles of electric riding since 2007, but only had to push once! It's good exercise, I used to do it a lot with my 1967 Triumph Bonneville, too.
More seriously, if you monitor your battery state (I just use a voltmeter, but there are more sophisticated ways of doing it) and your odometer, you should not be caught by surprise. My first conversion has an on-board charger, so I can mooch an "opportunity" charge just about anywhere.
Another consideration of course is to build a conversion with enough battery capacity for the riding you want to do. My bikes will get around 10 miles per kilowatt-hour capacity in city riding, but a bit less (maybe 7) on the highway.
As to self-discharge, it depends on the battery types. Lead batteries self-discharge at a measurable rate, and in my experience the nickel-metal-hydride batteries self-discharge at an atrocious rate. The ThunderSky lithiums I've used have an almost insignificant self-discharge rate, and the lithium polymers I'm playing with now also seem to hold their charge very well over time.
