It will be several months still... Lol
Actually I get almost exactly what is spec'd for my AGM battery based on drawing the stated average amps. If it predicts 3 amps will last 3...
Sorry to hear about the fall and car accident Bert. Hopefully all is well. I typically run my motor with a 4S lipo battery and draw only...
The PWM frequency was 8kHz, the vertical block is 10mV per division. Is your design sensitive to these numbers? I believe my ESC can run at...
OK, I measured my motor. Same configuration as i would normally run. Battery into watt meter into ESC into motor. I measured across the watt...
OK Bert...it will be interesting to see how my motor/ESC compares to your results. I haven't used my scope in years...hopefully it still works....
My ESC has over temp and over current protection. It is not software settable. It is much higher than 30 amps (150 amps or something like...
Sorry, i meant current peaks. Shouldn't the ESC input capacitors be smoothing the pwm pulses out? That is their purpose afaik.
Regarding the 30 amp trip point: It is interesting that you are seeing 2x voltage peaks at the battery. Is this normal? To me it suggests the...
Thanks, that helps a lot. It is 20 deg C here and sunny today. We just went for a nice day trip in the kayak. About 25 km. Winter is coming...
OK, understood. I'm still trying to understand one more thing. Given the existing design for a 30 amp trip point (I assume at 12v?), how do I...
OK Bert, that's great then. My mind is at ease! :) My motor has low IR so it will easily reach 30 amps on a stall. It will probably do that...
Your comments on testing at 12-14.5 volts etc made me think. What is the lower limit it will work? And upper? I had not realized it may be...
What battery voltage range will this work with? I am currently using 12v Pb and 4s Lithium depending on situation.
Wow, thanks a lot Bert. I can't really imagine doing all that without a debugger. I agree it should be "fail safe", I create enough of my own...
Sounds exciting...! I have 12 AH AGM battery that is rated 18 mohms internal resistance...over 600 amps with a dead short until something burns...
Dear Bert...please put your ground strap on! :) But in all seriousness, do you expect them to be robust in the circuit? Otherwise perhaps...
OK, understood. These units can also measure at a low frequency (500Hz?) if one is concerned about the iron core. I'm not sure if it will be a...
Personally, I wouldn't make that assumption. Papers have been written about whether physical L will increase or decrease with frequency and under...
I think that would be OK. I can't really see a big problem with putting it in the minus line. Documentation says around 500kHz.
