Currie, Schwinn, Mongoose, etc

I have a schwinn s350. And I charge the battery until the light turns green and I go ride it around the block and within 5-7 minutes, it's dead. No hills, I am running at full throttle through but you figure it would go further than that. Used a multimeter and it shows 24V before and after it is dead. I don't know if it is supposed to be like that or not. And how do you change the on/off switch? Just pry the old one off?

I have a Schwinn Electric Stingray with a fried controller. The unit was made by Ananda Power, and the specs are:
BLDC Driver
Model #EB2420DL/110
SN # 0513 6298

The throttle and hub moter seem fine, so I'm just looking to replace the controller. Any advice would be apprecaigted!

Thanks,

Hiya everyone!

It's nice to meet everyone. I'm Andrew. A 28 year old guy from South Bend (Home of Notre Dame Football!) / Mishawaka Indiana. I just recently got my hands on a brand spanking new never before used EV Powercycle 550. While the bike has never been used before the battery is having some issues as it won't charge completely and entirely (from what I can tell), but it still works wonderfully. I bought two bags for it, a hefty lock, and a very nice helmet to go with it.

The bike was stored in some old ladies basement and her husband and her never took it out for a ride. It was in mint condition when I bought it, such mint condition, the wheels still had the nubs on the wheels. :)

I got it for an absolute steal of a price, but I won't mention how much I got it for because I fear I may make a few people upset here ..

Anyway.. I look forward to learning how to keep this beast maintained and learning how to re-wire it when the battery finally kicks over to the great charging station in the sky.

I'm trying to build an electric motorcycle on a limited budget. I've bought John Bidwell's "EL Ninja" book, I can weld, I'm familiar with the fact that DC can kill, and I've got a fair bit of experience with metal fabrication.
So far, I'm thinking of either 60V or 72V of FLA group-24 type deep cycle batteries, an ADC motor (one of the smaller ones that will handle the voltage), whichever Curtis or Alltrax controller is cheap enough that I can afford it, and as many onboard 12V chargers as it takes to charge the batteries separately. All of these will be stuffed into a Goldwing or some similar large-framed motorcycle, running a 4.7:1 (or so) gear ratio, which should give me about 60MPH top speed with sufficient range to get me to work at that speed, or both ways if I go slowly (40 mile round trip).
There are a few questions I have, mostly revolving around batteries. Using separate chargers for each battery, they should balance themselves, right? I know that if I charge them as a pack with a higher-voltage charger, I'll have the risk of having a weak battery soaking up more than its share of the charge, leaving the others either over- or under-charged as a result. Another question - as the accessories on the bike are going to be 12 volt, is there a simple way to get 12V out of 60V or 72V? I expect that just running the 12V stuff off of one battery would unbalance the charges - but would the individual chargers solve that problem? My budget is quite low - a "solution" that costs several hundred dollars isn't likely to work for me, I'm more likely to opt for a solution that is ugly, or labor-intensive, rather than expensive. Any ideas?
