Re: Brake Lock: it should not happen!

Has anyone else experienced similar problems? btw, I am still running Nexens atm. Yes, I think so. I'm also on the Nexens in a Kona. My experience is stopping for the sudden appearance of wildlife. It feels like it is skidding, but I assumed that was just how the ABS feels. I assume there should be...

Re: Leaf battery pack for home storage?

Do you have a corresponding graph of the cell voltages? That is the important bit, as long as the cell voltages stay within the safe from damage range, state of charge is far less critical. Reducing the charging current at the 80% SOC mark would slow the remaining 20% recharging, much like a lead a...

Re: Leaf battery pack for home storage?

That counts solar charging out of the mix, not available for long enough each charging cycle not to take in all that can be produced until the battery returns to a satisfactory SOC ..... You've said this before, and although it may sometimes be the case, there are plenty of systems that give enough...

This one for instance: here 4.6 kg for 40 kW is light! 85 Nm is ok I guess. I'm not sure what I need though. They give this same figure for the 40 kW, the 50 kW and the 10...

Re: ZS EV battery warranty

Also service costs: I know from reading UK forum posts that the first year nothing needs to be done to the car, just a visual inspection and a software update. Second year brake fluid. Not until year 5 that the coolant needs replacing. Given that, getting quoted 'about $200 a year' and 'at most $30...

Re: Battery balancing is a thing

Apparently it’s good practice to regularly charge the battery to 100%, and leave on charge for some time, in order to get all cells up to balance at around 450V......preferably AC charging at home using the wall charger you bought..... This is correct for some vehicles, but others can perform the b...

Re: Polaris EV.

Interesting. How do you charge the Polaris? I.e. do you plug it into a charger, or do you plug it straight into the 240 V (and it therefore has an onboard charger). Is the original battery lead acid or lithium? Do you know the capacity, either in kWh or in Ah? The reason I ask these questions is tha...

Re: Ioniq motor replacement

Thanks for posting this, it lets us compare noises. Our Kona has a slight noise, but I don't think it is quite the same. We were wondering whether to bother reporting it, since the nearest service centre is 220 km away. Might see if it develops into anything.
Keep us posted!

I think it about adds up except for the weight. It says that 103 kWh of LFP is 100 kg. Perhaps it means 1000 kg? That would be about right for the LFP that I have worked with.

Re: 3-Phase Adapter

Unfortunately that 3-phase outlet only has 3 pins. So that will be 3 phases and an earth. You can't use the earth for carrying non-fault current, certainly not 14A continuous. So all you have is 400V+ phase to phase, which your charger will almost certainly not appreciate, and will likely get blown...

We are in the middle of converting a Mighty Boy, and the installed battery is starting to get low. Two of the LFP cells are down to 2.5V and the rest are also lowish. We have a 144V charger connected, and so we'd like to use that to charge them all up. But the charger draws 14 A, and there are no 15...
