Can I get a discount too? lol

If you need I can upload the video.

I disconnected the 12v from both precharge an HV relays and both went off. refreshed but data was not populating.
All this time the computer stayed connected to the inverter. Double checked that.

I made a video to be easier to understand.
Since I do not have a break cable connected I Downgraded to 5.27R. that code worked before.

I used a different switch for forward and reverse and also used the Prius Pedal that I used in testing before.

After work I will load 5.27R since that was the software that worked before, and I do not have a wire from brakes connected to the board. and load the default parameters for 2.19R. Those are the last default parameters published. I will also use clean power and disconnect the car from the 12v batter...

@ Johu

You know what. this gives me some hope. I do not have the guts to tell my wife that I have to buy another Tesla motor and board.
I have to check the ground. I will check that later today.

I just want to mark this as complete.
Conversion is complete but does not work because connected the 12v battery in reverse which caused some fuses to blow up but also I am guessing damaged the board and possibly the Tesla inverter.

I will post the progress moving forward on my you-tube channel.

This is 2 rows with 32 batteries each. I have to add another row on top to have 96 batteries.

Just to see how people think here maybe? He is a douche but I totally agree with his message in this video.

I will have to test the batteries. I asked the seller few times if the batteries have a barcode and every time she said that this battery type does not have a barcode. the barcode was scratched. I will see the performance after install. https://www.alibaba.com/product-detail/CATL-NCM-3-7v-116Ah-117A...

This is 6.8Kw, 16S pack. I will have 6 of these.

back at it again. I just got the new batteries. unfortunately I had to go with Lithium batteries because they are lighter and can do 3C discharge rate. I also ordered from China some fiberglass separators between the batteries. They wil be mounted in the front. Engine + transmision was 240Kg and 41k...

HI, (I'm back) After two Spinal Fusion surgeries, followed by a serious back infection at the second surgery site and a third surgery to clean out the wound and now daily antibiotics to suppress reinfection, ........... make sure you take Probiotics when you take antibiotics. otherwise all good bac...

@johu

the BMS cables that go to each battery need to have the same length? If they are not equal, does that affect the voltage readings ?

Thanks to Alibro I was able to save the can messages from the 2nd car. Not sure I will need them but I saved them just in case.
Alibro's video to setup this contraption:

Sorry for you.And it is not summer so you can ușe an electric bicicle.

I was not able to find the individual cell specs. but for the whole pack Leaf 2019 looks the best. The 2015 pack is not very good. Thing is that at 410Kg I cannot install it in the front.

did you win as its not viewable any more... do you have the bmw 330e over there as the 12kwhr batteries are relatively cheap (this side of the Atlantic) and its a good starter battery :) I looked few times at the BMW batteries and they are too heavy. From my calculations they are 101W/kg. that is v...

If and when I finish my car, but I would not drag race it. I would just like to meet with other people doing conversions.

You might be right. I guess I have to do more research. I am thinking that if the vapor is sent in a heat exchanger outside is transformed back in a liquid that is pushed back by gravity in the battery box cooling it.

I was looking at ways to passively cool the batteries using a liquid. Trichlorofluoromethane refrigerant R-11 has a boiling point at 23.8C. was thinking at a closed loop that goes outside the battery box that cools the vapor and transforms it back into a liquid that has a lower temperature. here is ...

One thread, two cars 😉 Nice that you're going at it again. Will be interesting to see how fast you move on the second attempt of the same car To answer your question directly, i can get to where I was in about a week and a half max. I just have to get the gas motor out which might take me about 2 d...

I will take it slower. I want to decide on the batteries first and test the battery boxes on the old car. then I want to balance the weight and put some in the front. I need to rearrange the some stuff in the front and probably the charger needs to go under the car in the back somewhere. It is all b...

I guess they only charged me $375. It shows my max Auto-bid there. I think the "reserve" was met at $375 and there it stooped since nobody else outbid me. They let you get in and see the cars every Wednesday, so I went there 2 weeks ago and saw the car. just to make sure. Screenshot from 2...

I placed an auto pre-bid of $475. I won the pre-bid and when the bidding started I won the car automatically because the company that was selling the car needed to get out of this car only $375 I think I did not know this and I paid $100 more. Next time I know and put a lower pre-bid. the price ther...
