Ok, alot of things happened over the past month..

I have hit the 2 and a half year mark on one of my batteries and one of my motors..

Here are the results....

Mileage: finally reached 20,000 miles

Front 36v (250w) motor: (Same Tire and Tube from day one. (not one flat!)

Battery: 36v 15ah From eBay vendor "Vpower" (1C rated continuous, 2C max discharging)
Over 1000 cycles, half of them using 12-15 out of 15Ah, the other half being between 2 and 12ah. *
Usable AH? (as of last month-march 1st):*
13.6ah to 95% DOD. (prolly could push it to 14.. *But that's close enough for me!)

Controller amp usage:*
MAX - 25a (start from dead stop)*
Typical - 8-12a (cruising speed of 18-20mph)

My BMS finally died last month from rain/water "damage"...

Been charging with my Vpower charger (set at 43.8 CC/CV) to "full" for the past month (no BMS))...
Used (via watt meter) up to a max of 12-13ah per *since last month...
Just took charger off and for the first time in a month checked each cell group, results?:*
EVERY CELL between 3.58v and 3.6v after 20 mins off charger..

What else could I ask for?!?!
 
Sounds like you've got an impressive machine there, brother.

This is good news; electrics are a great idea. Range and battery life-span are the real weakness. Apparently, though, that can be overcome.
 
How often, and for how long do you charge your battery? What's your max range roughly? Could you tell me roughly how much the entire setup would cost?

Thanks
