Following on from deciding my approach (see: Part 1), of getting the Battery+Motor+VESC+Remote working first before anything else, it has been time to read, ask questions and work out where to source items from.
My starting point for information is the goldmine: . There is so much there that it is a little overwhelming at first; however, when you鸿运国际网址官网下载安装 get it into it and understand a little more on what to look for it is not so bad and people are always helpful. Second to that is the Reddit sub: .
In Europe, there are a few parts suppliers I am aware of: E-Toxx, Unik Boards, Street Wing, ESkating.eu – all of whom have been helpful before and I would be happy to source parts from and get some guidance. This last point for me is really important, I don’t want someone to hold my hand, but I can see the need for some occasional advice along the way; hence, why I think it is important to find a supplier you鸿运国际网址官网下载安装 are happy to buy from, even if they are slightly more expensive than sourcing all the parts direct from China.
Choosing a VESC was easy, the dominant self-build and programme device out right now and readily available in Europe is Enertion’s FocBox. There is mature well-used software and helpful instructions out for it, and plentiful support. Right, sorted – I am building a dual-drive machine, so that is two to order.
Lots of useful information on Enertion’s site, as well as links for downloading the software:
Having had and tried a lot of remotes over the years, I care about the remote, both how it feels in the hand and the progression/sensitivity of the control. Not all remotes are the same, some are plain awful – just try the Eolve r1 (horrid), compared to the gold standard for me, the stock Boosted.
This part of the DIY market seems to be surprisingly less developed, with not many options. In theory, any 2.4Ghz RF remote can work with the FocBox, however, ergonomically I don’t want to do the over large ugly adapted model-car controller. The common offering is the Maytech remote although Enertion offers their Nano-X Controller I will do some more research but will probably go with one of these.
Battery (BMS & Charger)
Now, this is where things have got difficult; there seems to be no established battery unit builder and supplier in the UK right now. I don’t want to build my own battery pack – meaning soldering the individual batteries (safely) and adding a Battery Management System (BMS) – so am looking to get a pre-built pack like the popular to keep it simpler and safer.
Buying one from the US, from the likes of popular or , would be expensive with shipping and import tax; similar from China from Ownboard, Wowgo etc.; and the mainland European suppliers, like , will sadly not supply outside France. Trampa, based in Nottingham, only recommend specific batteries for their boards (), with links out to Ebay and HobbyKing.
One thing I have to consider is the enclosure needed, there are not a lot of enclosures available to fit underneath the deck (I don’t want a big sandwich box on the top of the board or hanging off the back), so I need to consider the dimensions of the battery pack and what enclosure I will sue with it.
I talked to Steet Wing and they are currently looking into sourcing some batteries for the UK, so will wait until they are able to offer an option, hopefully with a suitable enclosure. What I would like to avoid is the enclosure being very deep and limiting the clearance under the board and thus the style/shape of the deck. For example, the popular Samsung and Sanyo battery packs, available from the Chinese kit suppliers and used in the Foosted build, are chunky block shaped (needing min of 45mm depth) and not slim/flat.
There are lots of motors available, although I suspect a lot are just rebranded versions of the same ones.
For reference, motors model numbers such as 6355 and X are its dimensions – diameter and length, not a power/performance rating. Its “Kv: or “RPM/V” (Rounds per minute)/applied volt states how fast the motor will spin (depending on the applied voltage). A watt figure states its power rating, which typically for e-skate motors will be between 500W to 3500W per motor.
If you鸿运国际网址官网下载安装 want to understand what you鸿运国际网址官网下载安装 will need there is a very good guide to how to calculate the motor, pulleys, and gearing required on Electric Skateboard Builders:
I am going to hold on choosing my motors (size and power) until I know where I am going to source my battery pack, as hopefully, I can get them together and have some assurance, that (unless I mess it all up), the battery, VESC, remote and motors should all work together.
… project on hold, waiting for a local battery pack option. Update soon.
