Re: Custom KMX recumbent trike with QS205

update. took the heat sink back off to see the underside. I found a diode on the transformer that was reading wrong (not blocking voltage) so i removed it and powered the controller. it turned on. put a replacement diode and powered it... and it wouldn't turn on. So i removed the diode and started t...

Re: Custom KMX recumbent trike with QS205

Thanks for the information about adaptto. It would explain why I'm having trouble finding retailers with stock, most either are sold out or have the listing removed. That's a bit of a shame. I like the idea of the BMS being linked as well as the mode where you tell it how far you need to travel and ...

Re: Custom KMX recumbent trike with QS205

So i replaced all the mosfets, that was tedious as my soldering iron was having difficulty keeping up (its 60w) but the heat kept being pulled away from the thick power traces. I also think it would have been easier if i had a de-soldering station or wick. but alas I did complete the task and it was...

Re: Custom KMX recumbent trike with QS205

That's some pretty extensive explodies. I'd say the cost of the 24 replacements of 4110 cost me 115 (half what I paid for the controller) will be delivered tomorrow. is that just one phase? I wonder what caused it? Yep, just the one phase. Ground side. From what I gather on these forums is that sab...

Re: Custom KMX recumbent trike with QS205

I really didn't want to wait to hear back about the warranty... I have an event Saturday and next Thursday and next Saturday/ Sunday that I really wanted to drive to. So I took the controller apart hoping it would be a simple capacitor that was burned out that could be easily replaced... Turns out 4...

Re: Custom KMX recumbent trike with QS205

The cycle analyst will boot up normally and stay stable during my testing. The software of the BMS also has no log of shut down except for an over charge condition. (Which I know is from driving downhill on one of my trips (after I'd just charged) by all accounts the BMS appears to not be the cause....

Re: Custom KMX recumbent trike with QS205

usually, a cable get loosen somewhere, but in your case, the controller might be dead. It happened once to me, one of the big capacitor inside was not glued properly and one side opened and I had to replace the controller... most of the wires were tight, slightly loose screws but no arcing and I re...

Re: Custom KMX recumbent trike with QS205

Still haven't had a chance to look at the weight of the bike, or the boost setting. For the most part the bike runs great. The motor has a little stuttering when at speed but pulling low watts (below ~600watts) which I think is something to do with the hall effects and maybe the phase angle. (It's w...

Re: Custom KMX recumbent trike with QS205

I would start a new thread if it a new bike.

Re: Custom KMX recumbent trike with QS205

Usually, when the tire wear out too fast, it is due to toe in / toe out alignment. I would take a look at it. I got best result with 1/16 to 1/8" toe in on my trike. Ya had a feeling it might be toe, and upon looking at how it was wearing I had guessed a toe in issue... Once I was able to get my ta...

Re: Custom KMX recumbent trike with QS205

Sorry for the lack of updates, to say life's been a little difficult for myself would be a small understatement. Overall the trike does perform well, I enjoy having the ev plug, very handy for trips. Don't know the weight yet, sorry. if i drive slow and nice I get about 33wh/km, driving with a lead ...

Re: Custom KMX recumbent trike with QS205

So I managed to get the trike in a driveable state to get it out of my college shop... the trip to my new place after college was 102km ride... I totally expected the trike to make this trip no issues. I would have preferred to not have driven in the rain but it was my only option. When I left i had...

Re: Custom KMX recumbent trike with QS205

No haven't checked the weight yet, have to add a brace to the back of motor to stop the tire from hitting the hitch. And want to figure out why the main computer won't work, I can fix the lighting another day but really want Regen braking to work.

After some time of waiting for an online converter to resize them... Here are updated photos of the completed electrical boxes (10x10x4) and the over design of the trike with trailer attached

Re: Custom KMX recumbent trike with QS205

So I almost had it completely done, then I plugged in the trailer while the 12 system was on and destroyed 2 of 3 pwm lighting modules. After which I wanted to tune the motor response, throttle was ok but I wanted a faster acceleration, which I partly achieved but the initial response is way slower ...

Re: Custom KMX recumbent trike with QS205

Here's a photo of the trike overall (end of today's work in the shop) have it mostly assembled so that I could get a feel for the overall set up, defiantly think down the road I'll slim the design do and condense thing and lower the weight (should still be legal though, but we'll see.) pre-final ass...

Re: Custom KMX recumbent trike with QS205

I wanted to maximize range, plus the contractors that control the main battery have 12v coils and a dc dc converter shouldn't be left on all the time, thus you would need a 12v battery to activate the coils, and then a dc-dc could take over. I prefer to keep the light on a separate battery which all...

Re: Custom KMX recumbent trike with QS205

Ya, tried the bluetooth - it didn't want to connect. I from my test with the bluetooth i have a feeling It stays always on, would would be a decent draw over the course of the winter. might stick my amp clamp on the bms and see what standby power its using.

either way thanks for the heads up.

Re: Custom KMX recumbent trike with QS205

How was assembling NESE compared to vruzend? Any feedback would be appreciated NESE hands down. 100% better. The vruzend might have its place but overall not sold on its quality / durability long term. The hardware on them breaks way to easily. I managed to assembled all 40 modules (8 cells each) i...

Re: Custom KMX recumbent trike with QS205

At what speed did you simulate 300-500 km range? 40km/h - at full speed (70km/h it says 183km) granted it shows wh/km being 8 - I've never gotten better than 10 before the modifications when using a golden motor pie 5. And I imagine the results will be different as I don't have the exact specs for ...

Re: Custom KMX recumbent trike with QS205

In the past 2 days, I've finished the wiring on the trailer (minus the marker lights; which I'll worry about later) I also assembled the main battery. 74v 54ah... This thing is big and heavy and fits snug like a bug snug in a rug. I wire up the BMS and the shunt. The BMS bluetooth sucks but was expe...

Re: Custom KMX recumbent trike with QS205

One thing is sure... This trike won't go unnoticed! Just hope it gets noticed for good things, and that people can appreciate some of the hard work that goes into it. I'm wondering what the finished product is going to look like. It's kind of hard for me to see what direction the builder is going w...

Re: Custom KMX recumbent trike with QS205

This thing is starting to look more and more like an electric car build. Definitely one of the most street-legal fast setups out there. How many KWh of battery do you have for the main pack? With that vehicle, I'd personally go for at least 2 KWh of battery. Ya, I'm probably blurring the lines betw...

more progress, (which I'll keep posting progress until I complete this beast.) Hoping to finish in the next few weeks. I have the foam all glued in place for the bottom battery pack.
