Re: How do you think solid state batteries will change how we use hardware?

Im sure theres been a resistive setup used like a scalexteic controller, on a winters day under your seat i see its appeal but other than that its crazy inefficient. The world is about to explode and its all based around vr goggles, sony has a micro oled display that can produce a 4k image on a sub ...

Re: How do you think solid state batteries will change how we use hardware?

Stupid why we can not pay a decent amount for the cobalt mines to be explored in a non child labour deadly chemical way. Thing is some mill bits can be upto 3× the price of 15 years ago inflation adjusted too so where is that extra cost going if its still african kids washing their land away or what...

Re: How do you think solid state batteries will change how we use hardware?

why all the effort of making a giga press to then use a different cell type thats inferior. Because Chinese EVs are going to have to get by without cobalt, or everybody will have to get by without cobalt. Whoever does the best/cheapest job of that will win a major theater in the battery wars. Sligh...

Re: FLIPSKY new 20s 100A tiny controller (vesc based)

The whole point of an anti spark is too slowly deliver power to the caps so it sit on the positive rail allowing the voltage in the caps to slowly rise rather than a short harmful rise that in turn produces the spark we see down line from the direct loading of low resistance caps on a power source w...

Re: FLIPSKY new 20s 100A tiny controller (vesc based)

The antispark switches the positive 💯

When i blew mine up i got the fets to fix it strippes it down and the ground links on a straight through bit of copper but the positive pics up on the fets id keep it simple and go with the one antispark big enough for your needs.

Re: Best 125cc and under legal commuter bikes.

Doing a bit more digging its expected February 2022 in europe with a price tag of $7500/€6500 /£5500, does a 80% charge in 40 mins and its a €250 upgrade to add abs to the bike. Seems a little on the high side but inflation has been heavy lately and its a very well made bike with latest frame techni...

Re: Axial flux hub motors.

Traditional ebike hub motors have been very long vs their width so rpm has been traditionally slow but good torque production. These high power scooter motors are more square half as wide as they are tall making them spin alot faster by design. This square design will lend itself to rotor strength q...

Unused qs 138 70h v1

I got this for a project and found my controller will only run 14 pole pairs or more and this motor is 5 pole pair so its up for sale its the chain version and never been powered its brand new second hand. Im looking for £200 if you collect it from wales or you can arrange a courier at your own cost.

Re: Axial flux hub motors.

I dont think theres much difference in the manufacturing costs of them its more to do with the design engineer's taking whats been done and repackaging it rather than innovate which is likely led by the top dogs in the office saying costs to much cut corners or your taking to long hurry up etc. Inno...

Re: FLIPSKY new 20s 100A tiny controller (vesc based)

You will need a antispark switch for ease of use. You can make a 2 stage switch with a resitor to power up the capacitors slowly then switch over. I find the antispark switches good even if i broke one. You can roll the scooter forward the switch detects the motor emf and switches on after a set per...

Axial flux hub motors.

Why dont we see axial hub motors in use more often? Stand up scooter have tapped out the hub motor and gone to a dual setup to get the power needed to pull a human at a decent speed, 5kw or so for around 30 seconds and the motor gets too hot prolonged abuse at this level will see it enter the shadow...
