Re: Tesla battery day announcement

Unless Tesla improves their parts and distribution to aftermarket repair shops, that's going to be really expensive. I've thought about opening up a EV only garage, but working on Tesla's is a sketchy proposition. ??I've been using an old Tesla 15s module for 5 years now for DR. They could surely m...

Re: Tesla battery day announcement

Personally, i do not see the improved “million mile” battery as a huge benefit to the EVs..(.unless it is dramatically cheaper ?)...who wants a car battery to last 10-15+ years ? People like me who keep their cars for 10-15 years. And people who want to use them as second life behind-the-meter stor...

Re: Can't turn battery power off.

And all this I did with the power in "OFF" position :wink: So no chance I just encounter "residue" power. Do you know for sure that the switch is intended to remove battery power? In some setups it's just a signal to the controller to power down. If you are using a battery intended for another syst...

Re: Is DIY dying?

Hi all, I don't mean to be inflammatory with the title of my post, but I am interested in other's opinions of the direction of the DIY ebike market. There are more DIYers than ever. However, as a percentage of ebikes they are becoming smaller due to the popularity of mass market ebikes. And more an...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

The 2% of nuclei more massive than helium present in the universe today were created later in stars. And - fun fact - the only place in the universe that elements heavier than iron can be made is in the heart of an exploding supernova. So all those useful metals for wiring and alloying - copper, ni...

Stick a diode in there and sacrifice half a volt so the battery doesn’t discharge into the panel.
From what I can tell, prebuilt panels in the last several years at least, probably longer, come with the diode built onto the panel.
They have bypass diodes not anti-backfeed diodes.

Re: Wind and Solar vs Coal, Gasoline, Nuclear

Round trip Hydrogen is probably still well under 40% efficient and very expensive and makes no sense whatsoever for grid scale stationary storage. Agreed. Only way hydrogen works is if it's produced by high temperature reactors doing thermal dissociation of water. That allows scale to vastly increa...

Re: Are electric vehicles rated in peak or continuous horsepower?

Interesting. Why do we prefer continuous power ratings in e bikes then? Because that is generally how they are used. A 'standard' 250 or 350W motor is going to be at full power most of the time for most riders. Even my 1500 watt hub is at full power about half the time unless I am riding for effici...

So here is the conundrum I see on the motor simulator. Even at low speeds, the DD motor has the same range as the geared hub motor. Right. What about that seems surprising?

no LEDs lit on the BMS to indicate balancing was happening.
Most balancers do not have LED's. They use resistors to dissipate excess power from cells that are reaching their target voltage.
