Endless Sphere

please reserve 2 remaining thanks. PM-d.

4 units are on the way to liveforphysics, 3 NEW units remaining. I will also have couple used units later, they would go at a discount price. Please remember, this is not your average Eaton PSU, these are higher efficency. Almost the best efficiency on the market! Although if you buy 2 or more with ...

Yes - I can program 4 of them to 57.5 and max current.

Hi Luke, The best it could do is 57.53(3.6 per cell in case of 16S life), even if I try to set higher voltage it would not go there. And I checked the CC mode at 23.8volts it charges my tesla module at 40amps (I can actually upper it a bit to like 42amps, but default setting is 40) All this at 220v ...

liveforphysics wrote:Can you program them to be 58.4v and whatever it's max current is like the previous generation? Do they have CC/CV function?

They do CC\CV function. I will try to program one tomorrow and will let you know

Hi Folks, I have couple PSU-s with the very high efficiency. Eaton APR48-ES If you compare it with famous APR48-3G it would generate twice less heat! So more silent operation and overal better efficiency and power Could be used with adaptto controllers for up to 2000w charging power at 220-240v inpu...

for replacing R113 0603 resistor with 2-10ohm should be ok.

If you ever tried to motorcross with a 10kg\22lb hub motor in the rear wheel you would know that it is a bad idea.
Once again, It is a transportation vehicle, not a dirt bike.
We will make sure to eliminate pedals along with bottom bracket on our offroad bike

I know Elon Musk is pretty open about sharing his tech but the Tesla branding is a little cheeky :lol: Is this designed for 2 people ? I reckon the long, chunky moto style seat lets down the look of the bike. You know the name "Tesla" does not belong to Elon Must, don`t you? :D The owner decided to...

that`s for sure

It`s 100mm standart BB, like the one every fatbike has.

I was about to tell you using a hammer to make it fit, but looks like the seller already told you the same.
Artur, Is this your famous "warranty" work this way?

This is from the same manufacture with exactly the same quality

The next thing to appear would be the following I believe? https://lh4.googleusercontent.com/-IaKXR96MrGU/VMqIZIlKcWI/AAAAAAAAQmY/3zCzH3ZNngk/w1126-h1502-no/IMG_0310.JPG https://lh4.googleusercontent.com/-sQjkJaJp-Zk/VMqIZNnW5_I/AAAAAAAAQmY/keBo48cCAiI/w1126-h1502-no/IMG_0312.JPG https://lh6.googleu...

Hey Doc, have you tried to upgrade the firmware of the old max-e with new one? If you tried it could possibly flashed a new firmware to lcd display and refused to update the controller itself. Las lcd firmware could be not completely workable with older max-e firmware. In other words, do you have on...

A small clarification. This is NOT 3000wh battery. 2400max. Middle point is 74v. NOT 84v. And real capacity of element is 2.5ah, with 14p it give 35ah in ideal variant. More realistic data - 2.4ah and 33.6ah. Than you should also compare with ACTUAL stock battery data: 24s at 3.2v life would be mor...

It could be different welder. But looked similar.
The other disadvantage is you cannot use it for the large pack.

Very interested. What thickness tabs were you able to weld? What calculations did you use to size the tabs? What vendor did you use for the DN10? Link? Cost? I have not tried more than 0.3mm thick, But manufacture tells it is able to weld up top 2.6mm (what i doubt) but up to 1mm thick I believe it...

The fuse adds 7.5mΩ per cell. Which is ~10% for LG D1 and most other cells. From my test it is clear that these fuses are not very practical for high power cells, such as Sony VTC5. For those cells a different fuse design would be needed. I do have it in mind and will offer solution later on. So no...

These welders are too low power - my friend tested one and he succeed to weld only 0.1 nickel strip max. So I decided to get more powerfull one :twisted: DN-10 means 10kw I believe. 35AC barker is barely usable at 240V AC, 25a hits immediately when you try. btw wires are 50mm2 and they become quite ...

really nice design! However I have couple questions: -have you tested the resistance of your interconnections? I mean how many milliOhms it adds to the internal resistance of the pack? -what is the material? thickness? The reason I`m asking is when you playing with cells like LG D1 or Samsung 30B, t...

Max-E@72v LiFePo4 with Crystalyte 5403. 0-50km/h in 2.2seconds, how it that for an advertiser Andrey :) Just Awesome, Alex! Thanks for the vid, and for all Crystalyte 5403 owners now we know correct pwr timing settings for best acceleration :D although your video shows motor and controller temperat...

Once again, where is your evidence?
I have seen many dyno test datas on QS205 motors, the ones used to make Cromotors V2\3 from and none of them have 90+ % efficiency,
Please post one if you have it.

The Cromotor is > 90% efficiency. Where is your evidence? There is no data shows any version of cromotor have efficiency more than 87% ! If you have such data please share or do not tell anybody the numbers you cannot proof :) Looking at the 3rd row Max power out you see Vin = 69 Ain = 143 Win in 9...
