The ebay ESC seller sent me a flurry of emails,.mostly about how he/she is a victim of ebay and please reorder.
Histrionics and drama makes me disgusted and contemptuous of all humanity, to a higher degree than most all other ever increasing in frequency, and degree, of disgusting aspects of humanity.
I ended the exchange by saying all you had to do was link the new product listing and i woukd have reordered, but you sent me an invalid item number , which i was forced to copy and paste and search, only to find it non existent, and nowhere.else could i find it.
The ship has sailed, good luck.
Not sure what ebay was charging them for' promoting ' their listing, but if they just ate it and did not cancel the order.....
If it were not promoted i would not have seen it being 5$ less than any other listing, and that 5$ was ultimately not worth my time.
Been doing some reading on ebike forums about battery building, after searching for nickel strip ampacity.
Apparently 0.15 mm nickel strip at 10mm wide is equivalent to 22awg of copper and should not really pass more than 7 amps continuously, or.it will begin heaTing excessively.
copper is nearly impossibke.to spot weld on its own, but nickel coated coooer can, and the e bike anx e motkrcy le guys are apparently sucessfully stacking copper qwith nickle strips.on top to get the series connectcts resistance low
Im not going to be approaching Emotorcycle levels of dischaRge, and wi likely not even reach 50% of what the cells i ordered are capable of delivering.
But minimizing resistance is almost always a good thing, and while my hub motors cant ask for more tha 538 wattS AT ~25V, i intend to go to 36 volts, and perhaos they then can draw the 700 watts they claim.
Also, the crappy QC on ths imprecise hub motor has me shopping for other hub motors, and there are some with 540 watt ratings each, 1080 watts total, so i want my series interconnects to be able to handle tha much continuously, at the minimum, even though continuous will never happen in Florida unlezs i want to find the tallest bridge around and cross it over and over until something melts.
Towing the laden Fionayak is however exeeding the Load rating oc the esc, by at least 80lbs.
Good thing it is only a mile there and back, but that 2 miles uses at least half the 4.0ah battery capacity, and I've no idea what the individual ell rating is. I meazurex 538 watts acellerating just me to 17mph ish, but towing the Fyak i neex a slight downbill and tailwind to just barely hjt 14mph, so i got to assume 538 watts nearly continuous for the mile there, and back.
Something i did not yet confirm, is that going slower seems to use just as much battery, and the damn twitchy ESC cant just keep an 8 out of ten throttle but seems to jump from 5 to 10 averaging about 8.
