They actually dont have to be the same. This has been tested by Jack Ricard from EVTV. My numbers might not be exact but roughly, he connected 1 Tesla 85kwh pack that was 90% charged to another Tesla 85kwh pack that was 30%. The packs shut down. It was too much current. So he got them a little...

With all due respect, I dont think that is it at all. I dont have the specs in front of me but the Rav4 Tesla motor isnt nearly as demanding as the Model S and X motors. The big important difference is that the Rav TMS only operates when the car is on and in "ready" mode or when charging. All...

Oh good to know. I have a 2014 Rav4 EV. The car is made by Tesla and has a Tesla 41 kwh battery pack. I have noticed degradation after only 3.5 years. The peak voltage I have seen is 376 volts. The pack is a 92s40p. 4.1 volts x 92 cells = 377.2 volts so that makes sense. I was wondering why my...

oh ok. I was wrong. Thank you!

I have been thinking about this for a while now and I haven't read anything about it. This might be a stupid question but I need to know. It is no secret that 18650 cells/Tesla modules degrade with time. I assume that something inside the cars software knows how much degradation is there and...

I just found this. MIght be the way to go. https://www.electro-wind.com/rochling-glastic-gpo3-utr-1494-red-1-16x48x96.html

Hello, I am looking for thin sheets that are non conductive and fire retardant for my battery box. I've heard and seen that Tesla uses mica sheets in their battery box. I looked up prices on ebay and amazon and the stuff is expensive! Do you have any other recommendations? I need approximately...

Wow! Thank you Sunder!! You answered all of my questions in beautiful detail! Thank you so much!

So measuring the resistance is creating a circuit? I guess technically maybe you are right because you are creating a path but never in any of my years of schooling did anyone claim measuring resistance was completing a circuit. Can you send me links on these threads? If using my DMM isnt the...

Again, this doesn't answer any questions. lol I know you cant measure the resistance of a live circuit. I was measuring the resistance of a single cell. Was I not clear? Let me know if I need to reword my questions.

I appreciate that you took the time to comment but that isn’t my question. I already knew that. My questions are about the relation of voltage to resistance and about amp hours. If anyone else has answers I am very curious to know what you think.

Hello Everyone, I recently picked up a bunch of laptop batteries and I had a few questions. How does internal resistance relate to voltage? Does it? I want to test to see what happens when you put a low resistance cell and a higher resistance cell, in parallel, in a circuit. Lots of people...

Yup, I have already purchased the cooling fans. 2 - 104 CFM fans https://www.ebay.com/itm/Panaflo-Case-Cooling-Fan-12Vdc-High-Volume/122827850456?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649 Here is my project http://www.myrav4ev.com/forum/viewtopic.php?f=9&t=2191

Thats good news because I just bought one. :) Should be here in 4 months

I actually already owned this one so I dug it out of storage and used it to charge some 18650s. It worked great! https://www.amazon.com/gp/product/B01095RAH6/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
