Re: new eZip motor

No battery is safer then another. I would disagree with that. No battery is totally safe, but how many fires have been started your standard carbon zinc batteries? How many people have gotten chemical burns or been electrocuted by them? LTO is not safe, but the risks are different, and I think, ove...

Re: new eZip motor

Looking at a cheap trailer under 5 thousand that is worth fixing up and a plot of land or really cheap lot rent. This Apartment is 375 all utilities included so it is possible to do. Not sure if I've ever mentioned it to you, but that's part of my dream when I retire, or even when the kids are a bi...

I think for this one, rational responses is pretty much anything from "Almost certain to be true" to "Almost certain to be false", from the little information out there, I'd put it as most likely an accidental non-biowarfare release, as it was reported about 2 years prior, a Chinese researcher was s...

I basically don't even bother to use my in-car GPS any more, Android GPS is so good. You're probably running with a cheap phone that isn't running the latest version, and has a weak GPS signal.

Re: What could I do in the predicament?

You could wire the controller directly to the battery, then use a relay to switch off power if any condition except over-current trips the BMS (e.g. unbalanced cells). This will of course void warranty, and give you a single point of failure. If the controller fails to limit the current, or you get ...

Re: Phaserunner - Tips on sensorless tuning?

Did a bit more searching, and all I found my old threads from 2-3 years ago tearing my hair out getting sensorless working, and some other people saying don't bother... It seems nothing has changed in a few years. A pity. Oh well.

So, I'm giving up. I'll run fully sensored.

Re: Phaserunner - Tips on sensorless tuning?

Thanks. Not quite the answer I was looking for, but confirms my course of action. There has never been a problem with sensored running, and it is my short term solution to just get it back on the road. I have also relocated the connectors to be less exposed to water. But as I said, if I can get sens...

Phaserunner - Tips on sensorless tuning?

Hi All, So a couple weeks ago, shortly after the heavy rain in Sydney, my Phaserunner started acting up. You know that comment on thr Phaserunner page along the lines of "It's fully potted and waterproof. The connectors, not so much". Well, I found out the hard way it's true. The Phaserunner started...

That's rather morbid. I've been doing a bit of reflection on that lately, for two reasons. One, I celebrated my halfway mark: 1. I've been working for 22 years, and it's another 22 years until I can legally retire (well, I can retire whenever I can afford to, but it's the earliest I can access my re...

Not sure what context that advice was given, but if you're carrying both anyway, then yes, joining them is almost always good advice. It'll be good to see you active again - riding, and even working.

This is my bike: my bike.jpg It's nothing special. Built on a cheap Orbea frame, with a mix of cheap Unbranded, low end, and high end Shimano gear. Oh. And Q100H, oil cooled, pumped by a Phaserunner pushing 1100W. I never designed it to be stealthy. Only to avoid being a theft target, and police ask...

Re: parallel different packs

I echo Fetcher's post above, but add that since the cells are the same chemistry (or close enough), putting connections at the cell level would be preferred.

If you do the maths, even at differences of 2-3 tenths of a volt, the current between rebalancing cells is very low.
