Sorry they have gone.

The video shows winching currents typically seen are only 250a and seem to max out at 400a. He is using 2 75ah DCS lithium batteries in parallel and had no issues winching. Surely a 280ah battery could manage.

I'm in Australia and have ordered 4 times off Amy with no problem. On 1 occasion the Toll website said that my item was out for delivery when i fact they had just landed in Australia. Just wait and i'm sure they will turn up.

Unfortunately we have moved from our offgrid house and back to the city so i have no use for these cells. I have 8 x LF280n and 16 x LF280K still in the original box unopened. $250 each, pick up in Melbourne or can help out with getting them to you. PM here pleae.

Yes i was about to paint the west side and also use some left over insulation BUT we have just sold the house. Back to the city and grid for me :(

My solar equipment is in a 20 foot shipping container running North South. Its fine for part of the day but the afternoon sun beats down an entire side heating it up quite badly. It may only be 37 degrees outside but inside is much worse. The classic has been in there since 2012 with 3kw of...

I'm sure they didn't debate and actually tested many scenarios.

What did you end up buying?

Ill have to have a look when i have some time. It definitely makes it easier having the ability to run higher voltages and cheaper cable wise.

There are losses in transmission like you are talking about and there are losses within the unit itself. Midnite have a graph somewhere showing the efficiency of their controller with panel voltage V battery charge voltage.

I have seen a video where someone has a few controllers hooked up to panels and they watch how fast the controller can sweep and track. Not sure if they had any chinese stuff but midnite did seem to perform well

I have an American built Midnite classic. It's been solely charging my house batteries for the last 10 years (Australia). In the late afternoon the shipping container that houses all my gear gets to around 50 degrees C inside with no issues. It's extremely programable and support is great...

I think Ian from https://www.facebook.com/groups/SuperCapAustralia is working on or has a cranking BMS.

I think he is smarter than he lets on and goes into more detail than many channels. He also has at least 2 other youtube channels that i'm aware of. Busy man.

Yes i'm not sure why they are so much. I was about to do the same with our electrolux vac but ended buying a pre made pack off ebay.

Agree 100% What BMS are you using Kev?

I paid US$179 for 8x280ah cells to be shipped to victoria.

I'm just going by what Amy and i have discussed. I have paid the premium price.

I have never heard about any cheap cells. All quotes have been for matched cells.

I had to buy my cells in 3 separate orders due to extra import duties. When it came time to ship the 2nd order i was told the 1st batch was N but now will be K. Orders are spread by 2 weeks so would have happily waited that long to keep all the cells the same. 8xN cells don't have much use to me.

This one is AU$400 plus AU$18 per cell monitor. Not cheap but the big Daly aren't cheap either. This also has seperate contactors for charge and discharge which i think is a must. Why would i ever want my inverter to switch off if a cell went high? I don't have a link to this one but this is...

This is an Australian BMS that i will be using soon. Not as flash looking or anything but seems to fit the bill. These guys have been building batteries for a long time.

The BMS i intend on buying says to do exactly what you are saying. If charging to 3.5v/cell set equalise to 3.55v/cell once a week.

In case anyone is interested our inverter panasonic draws about 60w when under a high load and does taper down to 30-40w and will also cut out when everything is stable. At 60w the maximum it can draw for 24hr is still only 1.44kwh Also the freezer is always very cold so no issues there. There...

Ours has 9 temp setting for the fridge and i originally set it 1/2 way but ended up using 7-8. Another thing is no matter what i do at that 7-9 the meat section is just below zero and freezes meat after a day or 2. Great place to store beer though.

Model is Panasonic NR-BY552XSAU

I think mine has the same refrigerant.

Ours is in a typical double fridge sized spot in the kitchen but definitely not heaps of room as preferred. In summer our house is 29 degrees inside and the fridge runs flat out most of the time to keep up. Can be rather noisy too. I can't remember the model number but i checked a product...

We have a Panasonic inverter fridge. It uses around 1.2kwh/day but really struggles in the summer to keep the fridge cool and the temp inside varies a lot. We noticed milk and dairy not lasting on the usual midpoint setting. I measured the temp in a few locations and some spots were 8 degrees c...

I paid similar price to you. What are you doing with 205 cells?

I have done the same. What are you building?

No discount for bulk order?

How are they going?

Very interesting to read your testing. I'm still unsure which way to go but you might have convinced me to just build one pack. How do the rack type batteries get away with the problems brought up in the Orion BMS article?

Thanks, At the moment my SMA inverter is still working fine so will stick with 24v. Its a big investment to change inverters.
