    Building an electric racing motorbike from scratch

    Ah, I see you're using the nickel tab with copper bus plates. I found the only way this works successfully is if you solder the nickel inserts in place, which is a lot of work for a DIYer. Also, unless there's some thin copper linking the cell to the plate [aka nickel-copper-sandwich(TM)] the...

    So nickel all the way? Or any copper in the mix?

    Building an electric racing motorbike from scratch

    Nice work! Awesome to see some folks still keen on building race bikes here :) I too started with the motor and built the bike around it. Only way to go. Any details on the battery?

    Should We Be Worried About EV Battery Life in the Long Run?

    Most battery degradation will be evident in the first few years, and it tapers off after that. The main enemy of battery health is the unholy trifecta of heat, high states of charge and time.

    Captcha for this site wow..

    @neptronix, we've had some similar trouble with the AEVA forums. We're seeing huge surges in traffic overwhelming the server, and because it's shared, they shut us down with a bit of a hair trigger thinking it's an attack. More likely, it's a swarm of AI bots feeding on all the delicious...

    jonescg's eCRX pre-build thread!

    Being a front wheel drive, there's only a tunnel where the gear shift rods and exhaust went, but that's not the problem. The problem is the sway bar with it's raised bend (to clear the exhaust and gear shift rods) is just so damn close to the body I risk pinching the cables. I think having the...

    jonescg's eCRX pre-build thread!

    I started to re-install the HVAC and associated wiring looms. Also started to work out where to run the various HV cables - looks like the only way I can get them into the engine bay is via the cabin - the sway bar is too close to the bottom of the chassis so I can't sneak it under. Probably not...

    jonescg's eCRX pre-build thread!

    Starting to look like a car again! Mounting the 3 7 kW chargers will be a challenge - I've got the space, but I can't have the coolant inlet any higher than the radiator cap, lest it leaks out...

    Hope to have most of the fixings and mounts in place by the end of the weekend.

    Dozens of pallets of new LFP cells from ESS bankruptcy - SOLD

    But in all seriousness, that's an absolutely outstanding deal for a DIY crowd like ES. I hope they find a good home promptly!

    What unreasonable demands are the US making to 'resolve' tariffs for your country

    Yeah, had massive insider trading pump and dump vibes.

    Kelly Controls IGBT controllers 320 380v

    I don't know anyone using them, but they've had some half-decent looking AC motor inverters on the market for a while now; at least 3 years. Hopefully by now they've ironed out any bugs. But at that price, it's hard to go wrong!

    jonescg's eCRX pre-build thread!

    Quick update on the CRX project. I have taken delivery of the DC/DC converter and three 6.6 kW onboard chargers! Well, two, as I already had one. But these two have a CC/CP enabled so all I need to do is charge from a standard Type-2 EVSE and it will adjust the charging power accordingly by...

    Some thoughts on the future of automotive EVs

    There's still $3000 installs of 6.6 kW systems here in WA, but the average system is pretty big now. Finn has a good summary here - all prices in $AUD https://www.solarquotes.com.au/spottingadeal.html

    Some thoughts on the future of automotive EVs

    This is from a solar warehouse in Australia - the catalogue is a year old but the prices are in AUD and completely unsubsidised. They're no doubt cheaper now. Compare that to panel prices in the USA, it's clear there's a premium. Shop Solar Panels for Home | GoGreenSolar - I mean, US$300 for a...

    Was a good event - Shame Ron couldn't bring the Zero SR/S to the show.

    jonescg's NEW electric racebike BUILD thread!

    I suspect we'll be less competitive now that we've got extra weight and we're down on power, but would be nice to complete 10 laps trouble-free.

    Yeah, and despite the transparent case, I can still only see half of them because they're double-stacked! Rod Dilkes runs a business called EV-Power, he's based here in Western Australia. His original cell-top BMS designs are still used around the world but they're only suitable for low pack...

    Today Rod tested the new BMS brain and it appears to be working! Might be a year overdue, but at least we're going to be track testing soon!

    Would love to know how Steve is going! I can comfortably credit him with inspiring me to build my first electric motorbike.

    Solar Powered Supercharger

    Why do you need to charge your EV so fast? I charge my EV at 3.6 kW on a sunny weekend and never need more power than that.

    Electric Mercedes

    You don't need the gearbox with an electric motor. Or more accurately, an appropriately sized motor and final drive will have all the torque you need to get you to a maximum speed without the need for a gearbox. The Leaf motor and transaxle is good for about 90 kW, and the transaxle has an 8:1...

    jonescg's eCRX pre-build thread!

    In the interim, I was never happy with the RHS front mount being 10 mm higher than the LHS, so I get new parts jet cut. I welded them and fitted it. Much better welds this time around too. I also installed the new aircon condenser fitted, and a front pushing fan is on order. My throttle arrived...

    jonescg's eCRX pre-build thread!

    For sure - there's a much better way to get a custom shaft made than what I've got installed right now. But that required I knew what the final length of the shaft would be, and I simply had no idea until it was done. Now I know. So if the weld around the end fails because I get too carried way...
