Re: Volt bike Surron Road legal Australia
Stupid question - but in states where there is no LA class (eg. NSW) if you hold a full motorcycle license, can the 50Kph restriction be removed/bypassed?

Re: plug RCD trips houses RCD, why?
Does this in turn trigger the 'test' button to turn it off? Diverts a small amount of power from active to ground, causing an imbalance between active and neutral.
I think active is called HOT in the US?

"But with these 4 cells, they pull 0.3 amps"
Rooted. Massively high internal resistance. Not surprising they got hot.

Re: Headway cells stopped working... Help?
Hot cells is a very good indicator of high internal resistance - they basically boil off the electrolyte and get worse and worse.
High IR cells are only good for stationary applications and low current draw.

AUS - 2KW Downhill Electric Bike - SOLD
Inspired by the concept of the stealth bomber, I set out to make a batshit crazy, no holds barred downhill rig, but without the weight of a rear hub motor (which kills the balance of the bike). Its based on a Craftworks DHR frame, and uses a GNG 1Kw setup which drives through the gears - Pushed hard...

Re: Boost 110v AC to 120v AC or slightly more
Old iron core halogen transformers work well for this.
You set them up as an autotransformer. A 50W unit will give you ~4.5A, as you are only using the secondary to do the heavy lifting. Add more in parallel to up your requirements.

Re: Using a MPPT solar charge controller as a bulk charger
This MPPT charger will supply 82V at least, I've got it charging a 72V nominal battery bank, from a 50V 250W panel.

Re: Charge 52V Dolphin with this MPT-7210A?
Its a boost converter MPPT - if input > output, then this will happen normally.
There has been quite a bit of testing with these, and people are reporting decent power, 4-500W.

Chevy / Holden Volt modules are the cheapest. Not the nicest form factor, but easy to split into 48V modules.

Re: Voltage regulators
You will probably find that they only adjust the threshold of the LED for 'charger' systems (to indicate when the battery is 'full' - the current falls below a certain level). That's what the CH led is for.

And ECE papers also opens the possibility of sale to Australia / New Zealand as well, two markets with very little in the way of electric motorcycles, apart from the (uber expensive) Zero.

Current flow and potential difference are two different things. A current only exists when there is something bridging the potential difference (ie. your meter). You are seeing a weak current leakage current setting the case at the potential of the cathode, which you are measuring against the anode....
