That video did not at all contradict what i said. Which is that a Servo motor is limited by their controllers to a certain current to achieve the same torque across a wide range of RPM. This is desirable to have the same predictable acceleration / Torque. Having predictable acceleration is very...

That is a pic of a Servo ( which yes is a brushless motor ) In say a 3d printer it is desirable to have a flat torque curve to allow for fast printing without loss of steps.. in that example it has the same torque below 2000rpm.. This is achieved by providing a low inductance motor WHILE...

isn't 300amps to low ? Also is is 300amp that it can actually run at or is that really a 150amp ESC or is that the point of the testing

I have made some progress on the BMS front. Firstly the premise is that:- The load on the batteries "ESC" will be controlled by an arduino ( RPM) The charge on the batteries will be controlled by an arduino (enable/disable) Now since the Arduino already has control over what causes over and...

HAHHAHAHA +30°c today 😂

Life = 0.23 LTO = 0.06 Lipo = 3.12 18650 = 5.9 This is the difference between 25.5 - 10c expressed in the difference between them in milli ohms instead of percent like i had previously

The temps are there.... 25.5/10c One thing this has proven is that when stating a batteries IR the temp should also be mentioned .. Also it takes many hours for the temps to equalize.

i recon these LTO's are amazing considering there "Small Size" 32145 Im intending on making a video. LTO's have a wider operating temp, but for resistance i dont see there there is much comparative information in relation to Temp / IR.. Because these have such a low IR to start with it makes a...

Right group two of batteries LTO's and Life are all new cells in both groups 25.5c Life 2.65 LTO 0.34 Lipo 11.93 (new 5s) 18650 70.2 10c Life 2.88 LTO .40 Lipo 15.05 18650 76.1 Life 8.6% worse ( This Life was always much better than the other cell ) LTO 17.6% Worse Lipo 26.1 % worse ( new...

I find this extremely interesting.. while i had predicted the change based on temps i had not predicted the difference between the chemistries to be so pronounced.. I currently have them on my 3d printers bed with a cover over them at 65c . We will see.. Early results suggest similar disparity...

so first set of results in 27c Life 3.77 LTO 0.31 Lipo (4 cells) 14.63 11c life 3.93 LTO .40 Lipo 23.3 LIfe 4% worse LTO 29% worse Lipo 59% worse Interesting... especially when you consider 11c is not that much cooler than 27! Will try hotter tomorrow

Alex i'm going to test the IR of a Lipo, LTO and Lifepo4 at different temps... 27ish 4ish and 65ish.. it will be interesting..

IR will decrease with an increase in temp thats for sure. It would be really interesting by how much though ... But i couldn't bring my self to heat up a lipo ..lol i figure it would need to be heated up for some time to ensure it was heated through.. for me i could see the value in testing from...

Good work ... testing tx90 and cheap xt60 would be interesting too. Also i remember the days when "Deans" were an upgrade and were considered the best

I just want you to buy one of those AC resistor testers so at least one of your tests is directly comparable to the rest of us with the same test method.

Please Please Please Please Go buy one of these AC resistance testers and use it on your LTO's so we have some comparative numbers. Please Please Please Please For the good of the community.

WOW my batteries turned up and with my AC tester i got between 0.30-0.31 milli Ohms ! Awesome. This is less than a tenth of the resistance for the lifepo4 38120Hp ! DC discharge resistance at 10 amps 11-12 milli Ohms ( about 4 times less than the headways ) I haven't done a capacity test on...

I had a car running a roots type SC running 10 PSI @ 8.9cr and that 150% needed and had a IC.... In theory we should make more power with cooler air if we can IC. BUT at the same time IC's cause PSI drops and we find it hard to make boost in the first place. So it might not be that helpful in...

Also if i went IC that would increase the cost and it has already take 2 years to get to where i am now.. and i'm sure i have a few more years to go thanks to my tiny budget. O also i could take some cold air from after the air filter but before the maf and send that to the motor fans, but...

The MAF is not connected up as that is not a part of what i was mocking up. I was mocking up what was needed to be machined .. but it will come around the back and connect up.. But just before the Turbo inlet but after the MAF i need connect the crank case breather because where it is now...
