I found some specs on the discontinued parts only 38$ Esk8.
160lbs max rider weight
I'm in the 185lb range.
No doubt this limit is the plastic deck flexing, flexing the incorporated enclosure, whose battery is not designed to flex.
I can feel the other 350skate deck flex and twist underfoot too though. The trucks are the same. it is rated at 200lbs but has shorter wheelbase.
Anyway this excessive flex and itty bitty ESC in the 38$kate are going to prevent me from returning it to intended function.
hopefully. can never tell when curiosity will exceed wisdom.
But it was still great 38$ Spent. back up motor and wheels, black wheels instead of orange. and an itty bitty esc and hand remote for potential kayak thruster motor duty
and 6 18650s likely with only one cycle on them.
Im gonna be scanning the parts only eskTes listings, for similar deals.
The extra motor has me thinking about putting it on the front truck of my 350, for double the torque. this would require a dual motor esc, which can be had for as low as 43$, and the original 7s 1p battery would be woefully inadequate, and pretty much teeters on that fulcrum with just one motor
But I could then take the dual motor esc from the 700 and get a higher quality ESC for the dual hubmotor 700 with the desirable larger wheels.
The ESCs are basicLly for 6s, 7s, or 10s battery packs. 24 to 36 nominal volts.
If I am building batteries, might as well go for 10s for added torque and top speed.
But 10s will not fit inside enclosures, meaning fairly maJor redesign.
and when going above 8s, a huge spark can occur when hooking battery to ESC, possibly frying it, meaning antispark connectors become closer to necessary.
Rabbithole.
But a hideously fun one.
the road resurfacing has begun nearby. I located and explored some new pavement, about 3 miles there and back total, and some super rough roads en route which takes too speed from nearly 11mph, to maybe 5 and rattles eyeballs in skull.
The hub motor was really hot and battery was at 24.34v, or about 3.33 v per cell on my return.
under 3.3v it seems there is only 25% capacity left and torque and top speed are way down.
Some finned heatsinking of the hub motor seems possibly effective at increaSing range and longevity, but would depend on an epoxy bond, but perhaps a fastener is.possible too.
The Sapele platform is ready for final layers of Epoxy, but some much needed light rain has humidity levels high, which can cause fisheying and excessive amine blush, which then prevents proper secondary bonding without a whole bunch of extra work.
So its a heatsink kind of day.
so many heatsinks, in a box on a shelf, in California.
