Decided to start posting progress on my conversion of a Mazda MX5 as I have just got off the phone with my shipping agent and the batteries I paid for in Nov last year are ready to be picked up Monday, I'm sooo relieved there were times I thought I had blown 7000 bucks, anyway enough of that, I have 32 x 200 amp hour Sinopoly cells this will be my commute car I need a range of 84 kms mostly flat motorway driving, I have purchased an AC50 HPEV motor and controller and various other parts from Randy at Canada EV he's a most helpful guy so all that's really left is a charger and cables, battery boxes and put it all together, before I could start all this I had to build a place to work on the car,

Funny start to saving the planet had to cut down a tree this is a shot of the stump I had to dig out of the ground

Next picture is the finished carport and the engine nearly out after a full day's work the day before with Nick Smith who supplied the brains and most of the brawn.

Then I need a shed to quote Jack Rickard "to get liquored up and play with high voltage in"

Went to Auckland welding school and fabricated an engine mount quite happy with the result, I hand bent the ring with a bending machine and it's pretty much a perfect circle not an easy thing to make, I knew nothing about welding so although I probably could have purchased the mount cheaper I learned a great deal in the process and ended up with this, retaining the original engine mounts.

Matt and Rock were really helpful I took over a complete day of their time so the price really was quite reasonable.

I would like to put some form of rubber around the motor bracket any suggestions?

[albo2]

Just had a thought well 2 actually

1. Using innertube rubber
2. Putting silicon on the engine bracket and lightly clamping it to the motor covered in plastic.

Please let me know what you think

It looks good. I don't think you need anything between the motor and your mounting band. It would slow heat transfer from your motor.

You might want to confirm but I think you can run your controller/motor setup with 36 cells.

So when building the boxes maybe leave some room in case you want to add some more down the track.

Cheers.

Yes Im still pondering I might try 22 A123 cells in 2 lots of 11 cells each to supply any high current demands and prevent sag 32 cells should give me the range I want without taxing the controller

Picked up some unobtainium today, 200 amp hour black Sinopoly cells, yes they exist

Got the motor sitting in the engine bay today, was going to hire an engine hoist but saw these winches for 20 bucks at the hardware store when I was getting my paint, was a delicate operation, I wrapped the rope around my towbar to raise and lower the engine, worked like a charm, while I was working on it my Cellpro powerlab8 arrived in the mail, will be able to do some testing and confirm how much capacity these cells actually have, will also come in handy for doing what it's really for, fast charging my Helicopter batteries.

Good to see you with the Sinopoly 200Ah cells. Seems the measurements line up reasonably well, although its hard to tell with too much accuracy when the tape isn't square with the cell, I hope you don't cut wood like that. They are the compact 200Ah cells we've all wanted to see though, so that's great! Nice car.
