Re: Let's get your feedback - upgrading the system to phpbb3.2.x

Bummer, I used Subsilver 2 as well. Back to Subsilver and it's OK, but it will take some getting used to. The problem with some of the other themes is that they're just crazy laggy and slow! I didn't expect that. Anyway, I'm sure we'll all get used to it either way, thanks for your work and diligence.

Re: Data logging stream out of Phaserunner?

From my understanding, there is not a true "stream" of data. However, you can poll it using modbus serial. The controller is based on the accelerated systems BAC series controller, and they have some good documentation for this.

Re: Battery Life DOD SOC Temperature Charge-Rate Study

P.S. I want to see this data such that it is not normalized to the full charge capacity at each temp, aka absolutely capacity, to see where the crossover points are.

Re: Battery Life DOD SOC Temperature Charge-Rate Study

It's important to note that the discharge at lower temperatures is not likely causing the cycle life degradation as much as charging is. You can kind of think of it like this, the lower the temperature, the lower the effective C rate. This means that charging at 1C is more like charging at 5C at low...

Re: New 2017 updates to ebikes.ca motor simulator to try out

Gah! That's awesome! I've been manually backing out the human power by moving the slider around to account for the difference between the load line and motor output, but this is way easier and precise!

Re: boston swing 5300 battery 3000 cycles

The key questions to ask are: 1. 3000 cycles at what charge rate 2. 3000 cycles at what voltage (IE 4.15/4.25 etc) 3. 3000 cycles at what discharge profile/temperature (less important) how much actual capacity is usable It's not hard to get 3000 cycles out of even old LiMn cells so long as the charg...

Re: 2 Eltek Flatpack 2 48V current limiting power supplies

shipping to EU? Shipping is probably more than they are worth at that point I have to imagine. shoot me a country / postal code and I'll try to quote it some places. Germany , 80686 Munich It's not worth it, I'm getting quoted something like $100-200+, not sure why but it wouldn't work out. Thanks ...
