So I have this beautiful Loaded Dervish that I never use anymore.
I used to run it with a two Alaskan huskies in front in the city i was younger and we had a breaking distance of like 50 meters sometimes. If you planned your ride it was possible to do it relatively safe, I did go through a few left shoes though. Anyway, now we are all too old, dead or scared to do it anymore and electrical skateboarding seems fun!
I am going to need to shave off every penny if i am gona afford this project right now so im gona use the trucks and even the 75mm wheels and drill holes through them with a drill press.
Its a bit low with the 75mm wheels and it’s really flexible so i think I am going to have to mount the motor behind and up but im not sure.
I have done a fair bit of research for a few days but i still have a couple of questions. Here is what I am thinking:
Battery: Make it my self with 21700-40T cells. 12s2p or 12s3p, I have access to a spot welder ( I realise i wont get alot of range )
Question - Do i understand correctly that if the 35 contstant discharge rating on these cells is really 35A, i still wont be able to fully utalise the motors max current with the 12s2p configuration?
Motor: 3500W 85A 140 KV from Flipsky
Question - Will it be to slow? I weigh almost 100kg nowadays so i want the torque. but maybe because of the 75mm wheels i will still have that and should opt for a higher KV motor? the “same” motor comes in either 170 or 190 KV as well.
ESC: Really not sure
The ones I am looking at all have a continuous current paramenter of 50Amps, this confused me alittle at first since most builds including mine have a motor that when accelerating and going uphill i understand can recieve much more than that? Then i searched and realised that i could set the limit higher than 50Amps.
The question that remains to me though is how long exacly can i send lets say 85 amps to my motor without burning the continuous 50amp rated ESC? After how many seconds of climbing should i start to worry? I also appreciate any tips on cheaper ESC options that would work with my build. I want to have FOC though so i get that i wont be able to go all that cheap.
For the motor mount, remote, anti spark switch and pulley system the hope is that i can scavange and build it my self mostly. any links to solid motor mount builds is appreciated. How well does the clamp on ones that you buy work btw?
Thank you for any input. Bash away.
