Re: When someone asks "But show me an EV that can tow a boat to Broome!" Show them this...

The specs say:
Trailer Weight Rating (lbs): 5000kg
I'm guessing it actually means 5000lbs, or 2267kg. Even this is a very good towing capacity.
And 330 litres in the froot!
And AC power outlets!

Re: Low Cost BMS for Home Storage Batteries

Hi, I am interested. I have my old Imiev battery, but I need to find a compatible Grid connect inverter/charger. I looked at the Schneider, but they do not recommend Lithium Ion batteries with their chargers when grid connected. (But OK if charging direct off the panels, which is not how my system ...

Re: Low Cost BMS for Home Storage Batteries

Ok, I've finally got around to pricing these. The master module will be about $100 including the board (about $20) and all components. You need one of these - or two if you want a spare. The cell-top module will be about $6 each including the board (about $2) and all components. You need one of thes...

4 x 75ah 48v included. For $3999usd ($5500aud). Seems too cheap to have a mower bolted around it
You mean the Ryobi? It is lead-acid. Gives better traction!

Re: Bring on the BERM please

Been waiting for an electric ride-on, keeping our ageing petrol one going for 'just one more season' for the last few years.
Would like a catcher, but otherwise that Ryobi looks good.

Re: Numberplate ID for EV and Hydrogen Vehicles

Interesting. We have no such licence plate stickers in Tasmania. I was recently informed by an emergency services guy that he thought it was crucial. His point was that if a car has 'stopped' (i.e. no noise from the engine bay), an emergency services person doesn't expect it to go again. If I suffer...

Re: Low Cost BMS for Home Storage Batteries

Have you thought about making the board shorter but wider with all the components mounted to either the positive end or the negative end, then a cable to connect to the other terminal? That way the board would fit between the terminal and vent and the cable would go around the vent and make the mod...

Re: Prelude conversion project - some questions

Those NO thermostats - you stick them to the base or side of the charger? Indeed. Find an appropriate spot that gets warm once you've hooked everything up and see how the coolant works. I have two chargers, and I've added fans to both. I think in both cases I used screws to attach a thermostat to t...

Air Conditioning compressor - 350 V DC powered, uses 12 V signal and PWM to vary speed. Might be just as easy to set it to full speed and switch it on or off from the dash.

Re: Prelude conversion project - some questions

The water heater should be pretty straight forward, but I think I will need a small metal header tank. Any ideas on what to use as a header tank? A metal one will leak heat more than a plastic one. I ended up using a garden hose T-piece with the T pointing up. To that I attached a small plastic jui...

Re: Low Cost BMS for Home Storage Batteries

What I would like to know is if I can modify this BMS to use with the Imiev batteries, that I think are in blocks of 4 cells (I will know more when I get the battery pack back). Yes, I can't see why not. They have been used (so far) on LFP cells, I imagine that the iMiEV cells would be a higher vol...
