Just got bitten by this bug yesterday after helping my brother with the first steps of his build and have been reading through the forum here and at ES making a parts list for my own build.
Looking to put together something compact and relatively light; will be using it to commute ~2-3 miles over flat roads.
I’ve put together a detailed parts list here: https://docs.google.com/spreadsheets/d/1RNYZZSbDeuusBSgbq1e1CRSRdVisJzE7fKbwjH5OkD8/edit?usp=sharing but the gist of it is 6s2p (if I have the nomenclature right) with VESC and the beefier of the enertion motors.
I’d love general feedback on the compatibility of this setup; it seems roughly similar to some of the smaller builds on the forum. I don’t need to scrape the bottom of the barrel in terms of cost and would like to build something that I could expand (mostly in terms of adding cells for longer range) if this turns out to be a viable form of transportation for me. Also verification that the charging setup (charging the two 3s1p in series with the listed charger) makes sense would be reassuring.
I also have a few specific questions; I’m largely new to the world of DIY electronics so these stem mostly from the lack of experience/understanding with the wiring for the battery/esc/motor circuit.
The Enertion R-Spec has 5.5mm connectors and the Zippy batteries have 4mm connectors. It’s unclear what the connectors on the VESC will be. What’s the best way to handle these size differences? I’m not adverse to stripping the connectors and soldering the connections, but maintaining modularity seems valuable. Do people just make their own adapters to go from one size to another?
How necessary is the anti-spark board? I’ve been able to dig through details for lots of the other aspects of the circuit, but I’m still unclear on the purpose and necessity of the anti-spark, as well as where I would get one and how it is incorporated into the circuit? Even just a pointer another discussion that lays it out for an electronics neophyte would be awesome. Read a bit more and just purchased the Ollin VESC with the integrated anti-spark.
I’m totally entranced by the cleanliness of this build: DIY Electro-Trampa and boosted inspired electric longboard (https://endless-sphere.com/forums/viewtopic.php?f=35&t=73230) and am curious if anyone has insights into the connections he used as the charger and balance ports? I also posted a reply in his build thread so if I find out from there I’ll include it here in my thread.
What are the kinds of little bits and pieces that are often overlooked when getting together a build from scratch? Anything in terms of major components or bits and pieces that I’m missing from my list?
I wanted to get feedback on parts and the general idea for the build before buying parts. I’ll keep posting updates as I learn more and add pictures once I start ordering stuff and assembling.
Thanks in advance for help and advice; looking forward to sharing as I go!
