Thanks Chris! Most of those seem to have IP44 protection ratings, which makes them splash-proof (suitable for use in wet areas, if not sprayed directly). I suspect that's not good enough for an outdoor socket. Anyone know? Looking around a bit more, there's a French company called Marechal that make...

It's definitely a bit of a lottery whether you get caught for the import duty. I just got stung for £22 duty on around $150 worth of PCBs, but slipped under the radar on the same value of electronic components ordered from the US the same day.

8A is the input current on the rating plate Jeremy, but I'm sure you're right that this is just the inrush current, as the chargers are switched mode and supposed to have an efficiency of 90% (Curtis HF3). I realise I can probably get away with a 16A blue socket, but more than anything I was curious...

Maximum outdoor charging current?

Can anyone help me with a bit of advice about the maximum current I can draw from an outdoor socket at home? I have three 36V 30A isolated chargers that I want to use simultaneously to charge a 108V 60Ah battery pack. I'm hoping to keep charging time to two hours. The chargers will draw 8A max. each...

Yes, very impressive build. This is different in so many ways from the run-of-the-mill conversion (like mine). The electronics go way over my head, although I do recognise the flux capacitor in that sixth photo :D If the LiPo battery is 20p 10s that means a nominal voltage of 37.5V? Will you add the...

That looks like fun Evan. I've fancied doing something like this for ages but the part that puts me off is a nagging feeling that it would all go horribly wrong when I got to the bodywork. Maybe go for the minimalist look of an Ariel Atom? Here's one I like just because of its "junkyard" l...

He he. Sounds like your goals are shifting. Don't worry, it's a common EV syndrome. Treatment can be expensive though... Yes, the LMC motor and Alltrax 72V would make a good combination as well. You might also want to take a look at the Kelly controllers. It's a relatively new company and there were...

Thanks for the link Agnius, I've not seen that Alltrax PDA interface before. Either of those motors should work if geared correctly. I'd go for the high-torque RT version myself, as the extra torque could be useful getting a 300 kg trike up to speed. The Alltrax controllers are well proven units, bu...
