coulometer? Whats with this word and usage? Why all of the sudden peeps starting to use a coulometer instead of a wattmeter? "Coulometry determines the amount of matter transformed during an electrolysis reaction by measuring the amount of electricity (in coulombs)" We are not doing the above...

I have yet to open it, but dont want to open it just to look for the type. I bet some1 has some pictures here or info on what to get.

Can some one give me the bearing types in the leaf 35mm? thx

Now thats how welds should look like, no burned stains around the middle spot. Shows that the pwr spurce can give enough juice so the pulse is very brief.

Those welds do not look good at all. Just melted and not actually welding. What I think happens is that the current is so low from the battery that the kweld needs to do a longer weld and thus overheating. My battery gives me almost 2000A at 3,6V per cell (7,2V total i 2s config) I even need to...

Aand its off

Ok, lets hold our horses now. First of all, what is this in the red ring? What I see is a thin wire that is Soldered to the cable shoe in one and then soldered to a plug on the other end. Then, it is soldered again before it goes to a wire. There is so much losses in this connection that I...

A good battery should see about 5V drop at 100A Thats what I am getting with mine that has 5pcs 21700 Samsung 40T in parallel. Sure that the sag will be even less so if you have more Ps It is not only the cells that matters but also the layout and all the connections are extremely crucial. Very...

ANy will do I use different depending on the cells. mostly i Use 20s 300A version though. The thin one.

Sure, I use ant BMS with them.

I dont even know, I guess normal, or linear. Whatever is default on that thing. Reason why it is heavy is it is probably potted, so filled with material to make it waterproof. as for phase. I use 90battery/250 phase on my 12f but it only peaks at 200 during my rides anyway. you can easily see in...

Other nice thing is that you can throw two of your favorite measurement to main display, want the used or remaining Ah/Wh to be shown? You can put it in. You want max speed or voltage, yeah that works too.

Nice that you got the NUC now. At the beginning is seems very overwhelming, but you will get there, it is easier than lacing up a wheel. Also join their telegram chat group, you will get help very fast with over 400 members. Link: Nucular Electronics What I have connected is: Screen to the...

Why you hear the sound from QS motor might depend on the stright stator. The old crystalyte had an angeled stator that prevented this... is my theory.

TV, you never metioned that, after controller swap, the buzz from the motor is now gone when you are driving.
