Re: Assembled Hi-Power LiPo battery packs - any interest?

Not yet but I would figure just over 40 kg. These latest cells are only 113 g each.

Re: Assembled Hi-Power LiPo battery packs - any interest?

Wow, you do nice work Chris. What are the specs on that pack again? Thanks! I get better with each new one. Apologies to my first customers... It's 160s2p using 5 Ah pouches, rated for 35 C continuous. So about 6 kWh all up, 10 Ah, 600 V DC nominal. Has a main contactor, charge port, fuses, prechar...

Re: Assembled Hi-Power LiPo battery packs - any interest?

The number one reason high voltage battery packs can suck - too much BMS. BMS wiring on.jpg BMS wiring on leads.jpg The BMS of this pack is almost the same cost as the cells. 160s2p means lots of BMS. Hope to finish this and ship it easy by Tuesday. In other news, I'm now unemployed again, so I will...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

So you agree the planets surface is warming then? Good. Because that's consistent with the BOMs records. That's my point.

Re: Wind and Solar vs Coal, Gasoline, Nuclear

AEMO sees renewables as both inevitable and the right thing to do. Even a do-nothing strategy will still see at least 50% of all generation come from wind, solar and storage. Do a little bit more and you can easily get to 75% or more. https://aemo.com.au/-/media/files/major-publications/isp/2020/fin...

I don't think most of the ancillary equipment will run on a voltage that low. And if it did, the car would be a bit slow.

It can get windy, yeah. Through summer we have bitching hot easterlies and if we're lucky we cop the Freo doctor - a relieving sea breeze which never makes it as far inland as Kalamunda...

Question for the Perth (Australia) e-bikers

Just curious as to how much battery you'd need for an e-bike capable of Perth Hills to Curtin uni and back (or charge at work). I'm keen to push for a sealed path which cuts through Mundy park and reduced the trip by at least 5 km. Gravity alone will demand 100 Wh worth of battery, so I'm guessing 1...

Re: Assembled Hi-Power LiPo battery packs - any interest?

Bump. Another request for cells has come through, unfortunately well after I'd already ordered some. I can get them air freighted, but the cost significantly more - like AUD$20 per cell kind of expensive. Ordinarily they're around $16 or $17 each. So if anyone in Australia wants cells, let me know.

Re: Anyone use Phase Change materials for their packs?

There's a thread on Thermal Management of LiPo which covers some of this. Paraffin is probably the easiest to use - look for a melting point of 40'C or something, depending on your climate I guess.
