course participation in 2012

I am interested in attending your training course on building my EV for personal use.However because I came across your site only tonight (app2330 hours)I'm unable to attend your September programme in 2011. I live in Trinidad and Tobago in the West Indies,and plan to travel to New York in July 2012 .While there, I will then make arrangements to get to the area,in order to attend your training course in 2012 . Can you give me the dates and locations that you expect to schedule your course ,so I can make arrangements to attend one?.

the casing on my motor is stamped 48volts, my controller says it directs 21 volts to the motor, how can I direct additional voltage and amprage directly to the motor bypassing the controller on an on and off switch where I can use it for times extra power is needed such as going up hills, I would want protection for my motor but I am not adverse to rewinding my motor in a different configeration if it helps to keep it together.

Battery EXPERT needed

I have a 48v scooter that has 600w on the controller. What does that make the brushless hub motor? My batteries are 12v 12amp tab connectors. Are 14 and 20 ampers bolt conect only? I added another 12v 12amp batt.4 a total of 5 batts. How can I get more speed without doing any damage.

Compared SLA batteries, LiFePO4 was much more expensive, but it had super advantages on the cycle life, lighter weight, eco-friendly. We are all in one world, we need to consider more for the environmental and use the eco-friendly power solutions for our electronics and battery operated products, such as power tools, e-boats, e-scooters, HEVs, BEVs, Uninterruptible Power Supply (UPS), electric medical devices, Portable PAPs, Solar energy, Wind power, military etc..

Although Lead-Acid batteries have been broadly accepted in various applications, and their cost is cheaper than Li-ion batteries, shouldn’t we be concerned about its efficiency, safety and pollution problems?

Now more and more customers considered the environmental problems, and began to choose LiFePO4 batteries to replace their

SLA batteries step by step. And this is the reason that E&J develop 12V LiFePO4 battery packs build in SLA cases to replace SLA/VRLA batteries which were widely used by customers from worldwide.

E&J LiFePO4 battery is high capacity, slim and compact, and it is also functional under various circumstances because of its high safety factor.E&J LiFePO4/Lithium iron phosphate battery pack is very good choice of storage system because of its outstanding advantages of long cycle life, safety, high c-rate charge/discharge and high energy density.

Conversation of 1996 Honda Magna

I have just started researching converting my motorcycle a Honda Magna 750. I do not have a time line for my project but have been taken in a wealth of information and just figuring out where to start. Once I get started I will try and keep this updated with pictures and information for the project.

Zapino voltage converter

I have a 2008 Zapino moped that the voltage converter no longer works. The motor works fine on the 60 volts that the battires put out. The lights are 12v and don't work. I have been told that their is a dc to dc converter to reduce the power to 12 volts. I beleive that this unit has failed. has anyone else had this same problem and what did you do to fix it?

72 volt controller build . I need help getting it going!!!

I have an extra controller for anyone up for helping me with the build. I have 72 72 volt controllers off of 2001 GEM ne3v's. The are made by General electric and I have minimum experience in knowledge of their wiring and functions. I have not had any luck online finding a specific diagram that fits my controller. I want to know what kinds of motors I can use and if its possible to use a 500 watt motor with it. I don't think thats possible without blowing it up.... Hit me back someone..
