Just an update of the car. It looks like the voltage leak was just capacitance.
I have driven the car about 700KM this summer and it is operating pretty well. I needed to replace the black plastic Encoder on the motor as the car was bucking badly and I was worried I would have to pull the battery ...

I have connected the 2 newer modules to the Orion 2 BMS. I used the Orion 2 Tap Tool to confirm the wiring was done correctly - good. Now I am back to the original 8 module-96 cell battery. I'm getting ready to reinstall the metal battery boxes in the car and I noticed a slight voltage "leak ...

Yes it is.

Thanks JANOSH. The video was very helpful. I've checked the individual cell voltages of the new modules and they are all within 0.010V of 3.700V. The new modules will be added to the pack over the winter while the car is normally garaged. Stay tuned for updates.

I've installed the Manifold Delete and have put about 100KM on the car. I'm watching the motor temperature and cooling fluid temperature very closely to see if there are any concerns. So far the motor temperature has peaked at 57C after a couple of +100km/h driving stints. The temperature comes back ...

It took awhile for me to come around to buying the Manifold Delete, but I just bought the Revolt unit last week. Looking forward to getting the car back on the road.

Have you noticed any adverse effects of not having coolant running through the rotor? I have purchase all the parts to replace my failed seal and add a drain hole, but I am leaning towards buying the REVOLT Coolant Delete product and eliminating the problem altogether. Any comments?

Further update on motor rebuild - I have order 2 new ceramic motor bearings and a triple lip seal. The motor shaft is a little rough so I have ordered an SKF Speedi-Sleeve to go over the area where the old sleeve ran. I am cleaning up the water damaged parts and getting them ready for reassembly ...

I found coolant in the Encoder Wheel area as well and there was a slight score on the rotor shaft pipe. I drained the oil in the gearbox and didn't find any coolant in the oil as it was also still red & clear. The inverter housing is also clean and dry. For rotor removal, can you remove the motor ...

After a years hiatus from posting, I have a couple of new updates. The first is that the car is running well on a 300V-76 cell KIA SoulEV battery pack. It was originally a 400V-96 cell pack, but through some ignorant stupidity, I damaged two of the original four modules. The pack is controlled by an ...

You are the second person I know who recently lost their DC/DC converter. The other DC/DC failure was it just stopped working. No smoke, no warning but just stopped reducing voltage. I'm starting to think that if they get too hot, they can fail sooner than later.

I admire the way you are always upgrading something on the car. I have a couple of questions:
1) I want to install a 12V inertia switch that will open the main & ignition contactors if there is a substantial impact. Can I power the Inertia switch from the Inverter 12V supply or should it be ...

I am looking for a quick way to disconnect HV wiring from the battery to the main contactor box. I have been told NOT to use an Anderson Connectors due to the high currents involved under normal operation. I was looking at 600V welding cable connectors capable of handling up to 400 Amps. Any ...

Quick question. I will be finally updating my firmware from 4.85 to the most current version (5.20.R). Can I do it directly or should I update the firmware in steps (ie 4.95.R, then 5.10.R, etc.) I noticed you used a hex file and STM programming application connected directly to the board instead of ...

I liked the bolt-in cradle from F1moto because it fit perfectly into my Boxster space and left lots of room for a battery pack. It also came with two (2) drive hub adapters that were welded to a shortened Tesla drive shaft. If you are putting the car on the track, I would go with a fully machined ...

Welcome to the "Club" What motor are you using? If its a Tesla, you will need to decide on a Large Drive Unit (LDU) or Small Drive Unit (SDU) This is important because the LDU needs to be installed to run backwards. For the LDU, you will need a revese oil pump and depending on the drive board you ...

Yes Johnu, you are correct. I learned the hard way how NOT to test and operate batteries. I am making necessary modifications this winter to ensure everything is balanced before operating again with a new BMS.

Thanks for your replys on my issue. I do have the original BMS from KIA but I found it was only monitoring and not managing the cell voltages. I need to check my electrical connections.

Arber333 - are you suggesting to simply remove the damaged cell(s) and run on less cells?

Hi everyone. It's taken just under 2 years but I have completed the installation of a Tesla LDU into an 02 Porsche Boxster. The attached PDF takes you step by step through the teardown, experimentation/testing and final build. Be sure to watch the YouTube video at the end of the PDF. Enjoy.

I am also looking for information on these batteries. In September, I finished a project where I installed a Tesla LDU into an older Porsche Boxster. The car was powered by an 8 module 96 cell battery pack from a 2015 KIA Soul EV rated at 384V. I have been testing the maximum charging voltages and ...

Hi Jon. Do you have any units left to sell? I need one for my Boxster Tesla conversion.

Thanks for the feedback. I filled the casing up to the upper fill hole, which was recommended by another LDU enthusiast.
I will source the seals locally.

I have been test driving my Boxster Tesla conversion for a couple of week and have noticed oil on the concrete below the Tesla drive unit. The only source would be the gear reducer in the LDU. I don't have any leaks in the casing but I notice it very wet around the output drive shafts. Is any one ...

I'm not sure if this is the proper format to talk about a completed build using an LDU but I am quite proud of the final product. I also want to thank everyone who helped and assisted the build with suggestions on what works and what doesn't.
Thanks again. Take a look at this YouTube video.
