Re: Making new E-Bike, question about power

Hi there, long time no see. If you want 40mph cont and 100km range at reasonable speed, you will need will need a big motor (gearless hub 1.5kw-3kw, 6kg+) and a big battery (2kwh+/10kg+). So you will have a bike about 35kg, and the watts you need will also be a result of the requirements (above 300...

Hi, my cyclone 3000w freewheel start to make crank noises and catch the axis rotation when it wants to, something inside is just wasted.

''Disarm'' a mobile phone

Hi, I have some old mobile phones that I never want to use again, but I find appealing the idea of turning them into small game consoles for flash, mobile games or emulators. Even if I remove the Sim card and the internal anthena (that small chip) is the phone still emiting radiation of some sort? I...

Re: Safe cage, Really that important?

I see... maybe I can put something out of my old pc case, seeing a bunch of advised fireproof bags engulfing in flames whit just shitty small lipo's on youtube, I think I take the bet whit something of my own, at least I can feel double stupid if the case don't do the trick either.

Re: Question about % and charging

Thanks for all the advises, I get it more or less... but, even If I give the best treatment, the pack eventually gonna waste itsef as time pass because of the aging effect? Thats sad...

When that happens, I hope we have portable nuclear reactors like the ones in fallout 4 that fits in power armors.

Re: Question about % and charging

Li-on make out of panasonic GA 18650 cells.

I got a smart charger, 2,5amp whit 80% 90% or 100% option.

So, to go for 1000+ cycles, I must recharge when the watt metter shows less than 50v, and never let it drop below 48v, is that?

Question about % and charging

I plan to squeeze has many charge cycles as possible of my lunacycle 52v-24ah pack. I hear that the golden rule is not to charge above 80% unless you plan a long ride or want to balance the pack, and not let them drop below 20%. So here's the question, the readings show around 50.1v, Battery 52v, no...
