Hi all, this is my first thread on this forum. I've been popping in here quite a few times now, a lot of useful info can be found here.
There's something I couldn't find any info about in a form that I could understand, haha I'll need some help with this...
Ok, so I'm building a motorcycle. Small 125cc project. I've decided to use a supercapacitor bank to enable the bike to start from an electric starter motor. (it has kickstarter too, so not a problem if the pack goes flat). I went this route mostly because normal battery would ruin the look of my project, supercaps are nicely hidden away.
So, I've got a single row of 500F 2.7V capacitors (x6), each one has overcharging protection PCB on top. This is sufficient to start the bike, no problem.
I need a solution to slow down the current going into the capacitors in case if they go flat. The bike has a kickstand but if the pack is flat it will draw all the power and the bike won't start. I've been reading about inrush current limiters etc but electronic components are a bit like black magic for me.
Also I was thinking about diodes... Do I need them on the circuit? My understanding of electronics is very basic so every help would be appreciated. If there is a ready made solution on the market that would be great as my soldering skills are even worse!
The bike: Yamaha YBR125
Capacitors: row of 500F 2.7V capacitors (x6 so ~83F ~16V)
Max amps on the bike would be 15A (according to the main fuse on the bike)
I'm attaching bike's original electrical diagram. My supercaps would be replacing the battery.
Thanks!
