if they just kept it to one sentence, they might have pulled off a passable product description, but the more they wrote the more damage they did :lol:

Re: Mobipus Controller Official

No intention to provide it for aftermarket given the OEM demand. What is the situation for you samd? Will you sell these controllers or are you out? Since it's been some on and offs i'd like to know, there is a bit of confusion what the sales channels are. i think sam d has some and is good to deal...

Re: Good quality throttle

Probably catch some flak for linking pure Chinesium parts on a "quality" post but these are actually pretty decent. https://ae01.alicdn.com/kf/HTB1l.KgAeOSBuNjy0Fdq6zDnVXag.jpg https://www.aliexpress.com/item/Motorcycle-electric-motor-electric-vehicle-to-increase-throttle-speed-controller-NCY-large...

Re: 19" Motorcycle Wheels vs 26" Bicycle Wheels (rim and tires)

Hi, I changed from 26" MTB to 21" MC rims and tires. What I noticed is the huge difference in weight (~ 5kg per wheel, with rims, tubes and tires ) and also the reduced top speed. I was previously able to do about 70 kmh on a slight downhill, which is now down to 60-65kmh. I have the Shinko 244 (2....

Re: DIY spot-welder, FET-switched, processor-timed adj. pulse

so im looking to use the jp welder timer and make a suped up power board for copper welding. 24*1324 fets, in a double row, was thinking to use pure copper busbars, as opposed to aluminium, as i can solder to it. or better to use crimp lugs and plenty of auminium? any forseen issues with getting the...

look at better cells. 30Q have shown to have fast capacity loss. see es thread somewhere.. i have some 30Q packs, wont be using them again. oh and dont be fooled, they are not really 3ah, more like 2.6-2.8ah on a good day :D id be looking at some cells from es vendor tumich, id go for vtc6. it will ...

Re: mobipus voltage

I started off with 20s, now I'm running 18s. Obviously higher voltage is going to offer potentially better performance, but in practice you're much more likely to hit some kind of protection as you'll be close to the FET maximums with 22s. Personally I would go with 20S and re-package the pack to h...
