New issue to resolve. Decided to upgrade speed gauge thingy - removed original analog and installed a chinese digital display. Got everything wired and working well except speed. Initially connected phase wire signal to one of motors phase cables and got some reading. Nothing to do with...

Yes, it looks exactly like that :) I've checked it more than once myself too but no, rotation arrow shows it is on right way. I guess it has to be so. Avon AV71 Cobra is written on it.

In general now works fine!

One question to which I have not yet found a solid answer - what is the normal working temperature for a 3kW Golden motor bldc motor? I have 100 degrees Celsius set as max and 90 as thermal release set as default values at moment. Somewhere I read that no harm will happen even at 150 degrees. At...

Did some modifications to battery - separated two 24Ah sides and added one more BMS. So now battery max amps should be at 200A and whatever this 3kW motor is asking is there - should be max 80A but I've seen 150A draw.. Also upgraded main contactor from current 100A/12V switching thing to...

I think I might have the answer. (3)CurrentPercent:PhaseCurrentPercent.Range:20~100Functionaldescription:Themaxmotorcurrentis(TheValue*PeakCurrentoftheController).Suggestion:Factorydefaultis100%. So as my KLS-H has peak of 220A and desired is around 100A -> value should be about 50% Hopefully...

I plan not to do it anymore or unless I get hold of proper welder. With current one the results are far too unstable. One weld is perfect, next is too weak and did not happen and next burns hole into battery. I am quite good with soldering, been doing it for years and have an ok station at my...

Not really. I built it a year ago already but there is nothing special to it too. Just common nickel weld and smart bms. On the other side also nickel weld and then connected to together with 2.5mm cables.

Positive surprises keep coming. Interesting fact are that I was able to first change chain from 420 to 428 and then buy rear sprocket for that chain for Derbi Senda with correct bolting and middle hole. And after buy second sprocket and upgrade the size from 59 teeth to 69 and still have it with...

New rear sprocket arrived, now 69 tooth. Really big thing, almost 29 cm in diameter. Also made front fender clips for testing. Got fender lowered quite a bit. It really has all gone a lot easier than I expected. Kind of like bolt-on-kit almost...

The white might also work well. At moment I am happy with it as is. Light is strong enough. Got the front mask sanded and painted. And also attached and even made first trial. The result - rear sprocket needs to be replaced with bigger one, as was expected. Front mudguard is not doing its job...

Two battery halves now connected into one. Plenty of room for one more additional battery. All the wiring is also getting somewhere. All is connected and ready to go. Main contactor (big black thin on the left side) will be replaced soon with a stronger one. Current is actually meant for...

Figured the pre-charge thing out finally. I connected the pin 7 - Power - which powers the controller on straight to connectors motor side - so it was powered on when connector was triggered which is fine. What is not fine, is that even through pre-charge it got enough power to attempt powering...

Connected everything and it is alive. Only strange thing is that pre-charge resistor now appears to be of too high resistance. Voltage drops from 50 to 11 volts and Kelly KLS-H is not happy, making whistling sound. Will try with smaller resistor and see what happens. As it is the same resistor I...

Did some wire connecting, everything soldered. Fuses, blinker relay & step-down in place, also connected startup relay and battery bms. As the 48V relay came without holder or any means of fixing - made one myself. Printing will finish in 2 hours...
