Re: jonescg's home battery storage system

Hmmmm...... If I'd known that was the price, I would have bought it while we were over there and found a spot in the Hino some where so we could bring them home. Freight would probably make it prohibitive now, the premium on shipping lithium batteries is the killer.

Re: Prelude conversion project - some questions

The hose fittings were all available from an engineering mob is outer western Sydney back when I was doing engine transplants in various vehicles. They could make up any combination of pipe sizes, angles and 2, 3 or 4 way fittings, all machined out of brass and not very expensive. No idea if the mob...

Re: Newbie question about practicalities of charging and range

As far as the country area fast charging, are they on the grid or stand alone? I thought about this on my last trip to WA and back, a lot of gaps between the power poles out there. What I did see were a lot of solar arrays appearing at each servo. These servo's sort of double as the town store/pub/m...

Re: Is anyone using an arc welder with an offgrid system

Never heard of the MUST inverters so no information or experience with them. The Projecta intelligent inverter checks the incoming 240vac wave form to ensure it is clean and the correct frequency and voltage. It will test load it and see if it can supply the required load while maintaining the clean...

Re: Is anyone using an arc welder with an offgrid system

One solution may be to use a smaller inverter with an auto switch through when a stable 240vac supply is sensed on the mains input. That way all the low power devices can run on the smaller more efficient inverter and the bigger draw items powered by the big mother inverter as well as a supply to th...

I have 3 of those 40Ah Sky Energy cells if you want them. I check their voltage but they should be at about 3.2V. Haven't used them since the 4th one in the set died.
If Weber doesn't want them I'll put my hand up for them. They make great replacement 12v aux batteries for the Prius.

I'm guessing the diode pr are Schottky diodes. We use these quite a bit running around 40 amps through them and they do require the heatsink to dissipate the waste heat.

Re: EOI - New Yinlong LTO cells Australia

4,000 cycles would be every day for 10yrs, but as you say, a hybrid would benefit more because they are continually high current charging and discharging. To get the 2CA would require 70 Ah capacity, so 2 x 40Ah in parallel x 110 to build a 250v nom. battery. 220 cells x $84.80 = $18,656 ..... back ...
