Re: Thermal paste replacement interval

Thank you all, that was exactly what I was looking for, the painful part is, I asked at the local Jay Car last visit if they knew of any such product and I just got the wide eyed look like I'd asked for unobtainium or similar ...... Now, armed with the part number I'll have another crack at it and s...

Re: NSW Budget

I wonder if that applies to new car sales only, or all EV sales, both new and used. I might be able to avoid the rego transfer fee for the Blade I bought from Chris, the other subsidies do say for new purchases so I might be pushing my luck to get anything more eh :lol:

Re: Quality vs Quantity for Batteries?

Hi @T1 Terry if you are ok, can you share you planned arrangement with these LTO's? Is it a 144v pack? From some of your other comments I can see you like this chemistry, just curious if it's for an EV or off-grid power. The plan is for a 2p90s pack, nom. 216vdc 110Ah. The operating range is 1.8vdc...

Re: Thermal paste replacement interval

Is there a double sided sticky heat transfer material or heat paste the ISN'T electrically conductive? I have a heap of the cell top resistance type balance boards that I'd like to mount to a heat sink tunnel with thermostats on each face to turn on a fan if the heat sink reaches 50*C to see if that...

Re: Best way to rescue over-discharged cells?

Charge the cells to 3.65v, let them sit over night, if the cell voltage has dropped below 3.5v, charge them to 3.65v per cell again and repeat the 10hr rest period. You might have to do this a lot of times till the cells hold 3.5v for 10 hrs, at that point they are again at 100% of their capable cap...

Re: Quality vs Quantity for Batteries?

The 180 x 55Ah LTO cylindrical cells I just bought work out to $415 per kWh at cell level and would most certainly handle the high current draw as well as rapid recharging ... weight might be the issue though. If you reduced the pack size to enough to do the hill climb with maybe 10% to spare, it mi...

Re: Thermal paste replacement interval

It was a common fault back when the electronic ignition module was on/in the distributor. The module would fail and it was always heat related due to the compound drying out. It was a bit like Honda's claim that the power steering fluid was designed to last for life, when the steering components fai...

Re: Best way to rescue over-discharged cells?

Update: My daughter borrowed 4 lab power supplies from her science teacher (North Sydney Girls). Where three batteries in a row were under voltage, I set 12v. 2 batteries got 8v, 1 battery, 4v. I blew the fuse on the first attempt, then added a 1-ohm, 10w resistor. It went up to 250-degrees, so I a...

That's good to see because a lot sparkies I've met don't understand how cars work.

If you get in touch with Trev or Marcy @ https://www.drivebynature.com/ and buy a few single cell chargers. These will slow charge one cell at a time. When you get each cell to hold 3v after a few hrs the normal charger will take over. Do not attempt to fast charge the cells until they are above 3v ...

Re: High energy density battery pack construction

Yeah CNC'd from polycarbonate. But the busplates will sit atop the modules and tabs will link them to the cell tops. So, much the same idea if cells with studs on the ends were used. A seal on each stud that was squeezed up tight to the poly carbonate to stop coolant leaks down the studs. Then it j...
