We are living in Melbourne and the boat is sitting on the hard in Bundy.

When is the wooden boat festival?

Ken, If you want to see the WBF (& it really is great) fly over. If you are desperate for a bed, we could probably put you up and we live a half hour walk from the Dock.

Back to Li batteries. There is in the December Cruising Helmsman a response to the August article from Rod Dilkes of EV Power. Strongly recommends a BMS & details why with a nice pic of an exploded cell. Looking at their website, they seem to offer a more comprehensive approach (also more expensive) with matching cells and BMS. I've sent them an enquiry and will share the response.

I can thoroughly recommend the Wooden Boat Festival in Tassie. Went there a few years back. Good fun, good boats, good environment, good beer (Boag's is about as good as it gets), and more beards per square mile than anywhere this side of Portsmouth.

Lots of pretty flash blokettes about. But they seem to be attached to blokes with cable knit pullovers. Still, it's a great place to perve!

Likewise, there is a lot of information at the EV Power site: EV Power - Australian Electric Vehicle Specialists — EV Power - Australian Electric Vehicles sells Electric Bikes and car conversions, Electric Bicycles, Electric Vehicles, Conversion Kits.
The challenge for me now is to reconcile the varying views and come up with a workable, reliable and affordable system. EV Power offer some neat stuff, but they are quite expensive and the rather nice battery packs won't fit our available space

So, after all that discussion, I chickened out and went conventional. Just ordered 3 Trojan Deep Cycle SCS225 which should give almost 400 Ah for house batteries, and a fairly standard Century starting battery. Total cost is around $1000 or more less than the Li option, so maybe that will be for next time when there is a bit more consensus that it is a good idea.

Well, I think I might have done the same thing at this point. I'm still a year away from replacing mine I think.

Getting ready to do an outback journey for two weeks.

Default Overcharging batteries eyed in Boeing 787 mishaps

Does this sound familiar? And you know for sure they had the most advanced BMS in place and yet a thermal event still resulted.

Default Lithium Cobalt Dioxide!!!!!!!!!!!!!!!

Not only that, the batteries are LCO chemistry...the most unstable of all the Li-Ion chemistries. How in the heck did the FAA allow this to happen?

Just a few years ago, the FAA outlawed laptops batteries for that very reason!
