Yes, u r right.

Tesla uses 6831 cells cos it has a 250-300 KW motor. It is a roadster. Speed machine. Obviously it needs high powered motor and to run a high powered motor, it needs so much batteries.

But look at the new BMW 7 series hybrid. Uses a 15KW motor. And for a 15KW motor. But they still use Li-Mg Ion cells, which are not that efficient compared to LiFePo cells or Lithium Ion Polymer cells. I know they are dead expensive now, but just cos they are newer technology, it is expected. And one doesn’t need SO MUCH cells as compared to a Tesla Roadster. Its like you are comparing a Honda Jazz with a Porshe. :P

I am trying to find out a source where I can find these cells for cheaper price provided they can go for mass manufacturing it.

But you need to help me out as how do I assemble this on to the same shaft where IC engine is transmitting to run in three modes, Electric alone, IC engine alone and both simultaneously. Also, I thought of a brilliant design to charge the batteries on the run. Not some regenerative braking or crap like that, but something more efficient. Simple and practical.

But as of now, You are the one who can guide me as how to assemble this kit onto the existing system, the components required, etc etc. Can you help me with this?

And btw, I am not talking bout those pen cell size Li-ion cells with 3V each. I am talking bout High Ah high volt batteries. Preferably one or max 2-3. But not more than that. Also they wont be bulky as Lead acid. I am working on that one. But I need your help.

I think you have a great idea there. Cost wise, I am not sure if the lithium ion polymer cells are applicable for commercial usage on electric cars.

The top range electric car on the market, The Tesla Roadster uses 6,831 lithium ion cells. Maybe lithium ion polymer cells can be used on hybrids. You have to do further research though…

I did notice that the cost of the EV shoots up cos of batteries. I am actually planning to build commercial kits which can be connected to any existing car and convert into hybrid. But at the same time, I don’t want to keep the prices high. So can you help me out or give me some practical suggestions.

Instead of using dozens of bulky Lead acid batteries, I was thinking for going for lithium Ion polymer cells, but if u can suggest me something else, practical, lighter and cost efficient, it would be just great.

I intend to do this for a good cause. But I need help.

[...] Now, before you start the conversion process, it is important for you to choose the right electric donor car. The rule of thumb is, less weigh it better. Hence, go with a lighter car instead of a heavy SUV. Remember to put “storage space” into consideration. Unlike a gas driven vehicle, an EV has to carry its own power source which is the deep cycle batteries. [...]
