Re: Tesla PW2

Big bugga, how much real useable capacity in there? Can the 5kW inverter actually pull a continuous 5kW out of the battery until it is fully discharged? T1 Terry Hi Terry, the battery testing centre latest report ( click here ) provides really good objective data. Yes, they can pull 5kW constantly ...

Re: EV-Only "Fuel" Tax On The Govt Agenda

I think taxing tyres would be the easiest way to get a road use tax... Huh, that's outside the box thinking, great idea! The only issue I can think of, since tyres easily last more than 30kkm these days, the tax will need to be more than double the price of the tyre itself (using 4c per km cost fro...

Re: Simple (to use) wall mount =<7kW open network

Even 15A Australian wall socket will do (that opens 24/7). The problem with the 'RREV' (a.k.a. gen-1 Leaf), the b...

Re: Hyundai Sales Tactics

Re: Are hybrid bikes worth the money?

Echoing what Mike has said. However, without suspension, make it easier if you're a DIY-er though, i.e. long term maintenance.

Mine has run close to 50,000km (over the top details here).

Re: Offgrid solar project

Is there a buck converter that does say 96V in to 48V out with 600W+? I had a quick look and didn't see one. The other issue I have is a simple buck converter has a tendency, when they fail, to supply Vin to Vout. So 80V input to a 48V inverter would be bad. Ah yes, you're right, the only one avail...

Increased Internal Resistance

While the crowds want more battery capacity, I'm content with more fast charger networks, i.e. stops more. However, I recently found out the degraded battery of my Nissan Leaf considerably increase (fast) charging time, i.e. more than doubled!! Yikes!! :o My 'Hx' degrades pretty bad, and slows down ...
