It is an important step and I can not see why it is not in the present manufactures instructions. I have two cell going through another 12 hour charge these were the first to drop below 1 volt on the last discharge test but I did get more than 100Ah out of them problem is its wet and cloudy for the...

Hi Andrew, I've missed where you mention what car you have to match up what switches you are looking for to get the stock equipment look. My Prius has had seat heater pads added by Jason, the previous owner, he used 3 way rocker switches mounted on the side of the seat so they are not really seen an...

Not good news at all David. How do the third party person insurance rules work in Qld? In NSW, because the vehicle that hit you was not driven with the permission of the vehicle owner, the TPI mobs will wriggle out of paying a claim for injuries you received. Make sure you regularly attend physio fo...

The whole cheaper to be processed overseas would change and jobs would return on shore if carbon miles pricing was added to the freight costs. The $44,000 drive away is starting to get towards a competitive, well, as long as the twit in South Australia doesn't get the opportunity to add the petrol e...

Is anyone able to explain the reason why it cant be done, my electrical knowledge is only that great. Also is there any device i can use, maybe reverse polarity protection or something to allow it to happen. I'll try. The problem is the lack of isolation. Each side of the so-called "DC bus" connect...

Half ya luck, getting things engineered before they can be registered and that changes state to state so a new engineers certificate if you move interstate makes the whole vehicle modification scene a dying art over here. I'd love to do a Eureka conversion, so many drop in kits available to bolt up ...

[/image] Hi guys, Here's my 1970 Beetle I've been restoring for the last couple of years. In the last few months I've finished the panel and paint and now I'm starting on the fun stuff :) Mounted on the original transaxle is a Nissan leaf motor and inverter which will likely be controlled by an ope...

sadly my one uses an obscure communication language called OBD-M or multiplexed OBD, so man in the middle adjustments for me my main issue is how to the car from over charging, or overdischarging individual cells. I was looking at orion bms with the simulated virtual battery function to take care o...

Sorry if this is dragging your thread off topic Matt, feel free to delete it or move it if you want. Looking further into Mathew's post, apparently the LTO cells can handle a lot more current in both directions that the lithium ferrous cells.... or have I got that wrong? The Gen 2 samples at every s...

Shitte, I'm glad I only do off grid solar/battery/inverter jobs, that all looks like a massive headache for very few $$ return from the grid. I do enjoy giving the grid supply the "bird" when they ask about certain items they consider are an essential, like the fire starters on the solar arrays .......

Have you seen the episode on the Electric Samba where he links the cells using wire he tested to fail at what ever current to create a safety fuse just in case a cell went short circuit? Have you thought about filling the whole battery with a non conductive cooling fluid so it can be cooled easily a...

PM on its way Chris

The gen 2 would probably do better, does yours have the ev button? It sure does. By using two current shunts, (a 75mv 200A and a 75mv 100A) only 1/3rd of the current should go through the original battery ecu current sensor, meaning the original battery guage should be rescaled to 19.5Ah I really l...

These border issues are getting worse eh No worries, maybe a few more tired EV packs will come up in the future that I can scavenge a few cells from ... or maybe even the whole pack if the price is right

T1 Terry

What price each? I'll take as many as you will part with if the price is good .....

Hi, If only the was an electrical device that could be incentivised /subsidised that could soak up a lot of the excess solar energy during the day and be hooked up so it can push power back into the grid when it's in high demand.... Wow! I had an idea for such a device: I thought make it out of nic...

RIP Jack, 65 is way too early to fall off the perch. His EVTV weekly shows on the interweb was my entry point into the whole conversion world ... and probably my caffeine addiction so I could stay awake through a whole episode. Stopped watching it when his co presenter left, it just got too slow aft...

With my set-up being a hypoid design, the pinion bearings and gear teeth were originally submerged in the oil as well as a oil catch port as part of the cast iron that collected the oil tow from the crown wheel and fed that through the pinion bearings as well, I guess to ensure there was oil flow th...

Any news Chris? Any idea of price?

With NMCs, the balancing is done at any voltage, so the end of charge situation is different. It is spending hours in the last top-up phase. I've found that the cell voltages are the same (about 4.02 v) 24 hours after charging is finished. With the balancers operating all the time, how do you deter...

It is a bit big. You would need 4 units to do a 14S lithium pack which would be almost the same volume as a cell. Not exactly sure how you would do a 14 cell in series pack, 16 in series required 5 units, one for each 4 cell group and one to balance the 4 x 4 cell groups. If you balance in 2 series...

How many do you have? I'm interested as I need a few as well.
Chris, what is the physical size of these cells and how many do you have?

Wow, that is a very high oil filler/level plug, is that standard? I would have thought that much oil being churned up by the crown wheel and pinion would cause issues with seals ...... The diff in my big bus project has been rolled over and because it is a hypoid set up, pinion is below the centre ...
