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 :wink:

You know the name "Tesla" does not belong to Elon Must, don`t you? :D The owner decided to name it this way, I could not stop him from doing this :) Yes - this is the special version long seat, it`s actually from Teleporter Heavy frame and designed for 1.5 people, In case you want sometimes...

UKq9ob9s1Fs that`s for sure :) It`s 100mm standart BB, like the one every fatbike has.

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...

Than you should also compare with ACTUAL stock battery data: 24s at 3.2v life would be more likely 76.8volts and probably close to 16-17 max actual AH if your battery is new and has no defect cells. So only 1300wh in real world on stock battery... New one still gives you almost twice capacity...

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

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 would not be a problem, as i use only ~1,5 setting from max 10 available :) here is the link if you can talk Chinese :D...

I`m tempted to see these design for high power cells :) 7.5mΩ per cell fuse is probably ok, but couple words about metal used and thickness?

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...

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...

I`d better say, "upgraded" :)

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.

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 :) You cannot compare motor power at different RPM, If you look closely at the numbers, there is almost...

Here is the small one and the large one
