Re: Watt hour for lippo and lithium-ion

sorry for misspelling lipo. I can calculate wh, but what I actually mean is that if you discharge the same wh battery you can go the lipo (this is purely theoretical) to 3volt and the lithium cell to 2.5volt, and my question is whether this results in longer distance? Because you start with both of ...

Watt hour for lippo and lithium-ion

Hello I have a question about the wh between a lippo and a lithium-ion. If i have a 30ah lippo pack and a 30ah lithium-ion pack wil i theoretically can drive the same distance? I ask this because a full lippo is 4.2 volt and a empty is 3.0 volt but with a lithium-ion battery full is 4.2 and empty is...

Re: Torp 11kW / 29kg mid drive electric free rider prototype

I think this is a big gamble of 7000 euros, that you pay for you have seen even one test of it. You have to believe their word that all these figures they give are correct. For example, I have never been able to drive 2.5 hours fast offroad with a 1.8 kwh battery and with a 15kw motor. You may still...

I don't know if this has already been discussed here, but I would like to know if it is possible that you can switch between trottle and passensor via one of the three settings? So you can easily switch between road-legal and off-road :wink:

Re: Hacker motor

If I understand it well it will give 0.26 nm /amp, so if you feed it 150amps it will do 39nm and if i multiply by 4(gearing)it will give 156nm at the rear wheel, thats seems nice :o

Re: Max erpm and field wakening

I don't know if it's relevant, there is a thread by Lebowski where he added external field coils to change the field, which increased the eRPM of the system. Not sure if field weakening would do the same thing or not, as I don't really understand most of what's in taht thread. :oops: https://endles...
