Re: Electric kart

Those plots are interesting to follow some high speed points that must of been downhill or less incline with lower amp pull at full speed and another area with the 120kph/75mph taking the full 50ish kw peak and a sub minute lap.

Like that alot.

Re: Hubmonster teardown

That's all assumptions on my end with the manufacturing ive not compared them but its logical to make things simple as possible in manufacturing so it saves time no mixed up parts and reject numbers go down when that one process is finessed then sped up.

Re: Amount of cells? many or few

stop with the outright mistreatment of facts. your opinion is NOT facts and $/kWh is not a factor when talking about safety. if you want pouches to be at the same safety level as cyclindrical cells are you need a LOT more money and mass to compensate the fact that you MUST have compression and cras...

My honest truth id dump 18650 on a bike and go for a prismatic less connections to worrys about and on a bike that bashes about the road vibration is gonna find any weak links over time so for road use id want a fully potted pack like tesla do it or prismatics with flexible tap connections to absor...

Re: Amount of cells? many or few

i dont use that double row stuff for this reason. its too restrictive for most pack designs or real high currents. and often cheap steel. i use hex shaped holders only if there is a space restriction. otherwise i only use straight holders so the pack is stronger and there is more air between the ce...

Re: speed relationship between wheel and bike

I think the effort it takes on the bars proves that turn in is easy one finger but turn out requires more effort and at that point there maybe a little wheel variation on the front but i cant say for sure im not reading all that.

Re: Hubmonster teardown

4 gauge :shock: thats 25mm cable and 2 sets of that just wow the side cover bearing must be a big boy, if the rest of that hub uses a big enough chunk of steel and copper it may get in to triple kw figures but surely it be huge like 300mm dropout in a 13inch wheel 40kg type huge.

I built a battery for a Ym Wuxi 6 phase motor. Six fat ass phase wires. 12 or 10 inch motor for a scoot. Idk where it came from or how much it cost but it had (6) 4 gauge. It was stolen off a porch in Canada so I'm building another. The goal was to see 600 amps. This topic is interesting. I would l...
