As for those file transfers, the large files like your screenshot of a video file will transfer quickly, about 100 MB/s. The groups of small files such as images take a lot longer. In my head, it has to start a new file, fill it with data, close the file, update the MFT or table of contents for each...

Half the prop above the water. That is bizarre...

Hi all I'm having an issue with my 4s 80 amp Lifepo4 bms mounted on 4s of 60ah CALB cells in a DIY power case I built. When I charge with my 20 amp wall plug charger, the xiaoxang software dies. It all works perfectly while discharging. My loads are up to 50 amps. Would appreciate any input ✌ Is th...

The balance between the cell group voltages looks close enough to me, where I wouldn't worry about it right now. Measure the voltage coming out of the charger with a DMM (multi-meter), and the voltage at the charge connector that you're plugging it into, and then report back. Most chargers have a b...

Oh, so the cannondale is still a better frame for speed than the Maxarya is? What's the differences between the two?

I had to look up what a Maxarya Ray-2 was, and $

At least something like this is still being built! Any thoughts on front suspension?

Fjp, I just saw in another thread that you've been holding out on us! The Bike-E looks to be operational, and you've been using it in the gravel I take it. How do you like it, and what kind of trips have you been on? I do now have two 20" front wheels for my recumbent, and I swapped them mid ri...

I'm glad to see you around recently, and that I don't have these goatheads in my area! Aren't there small scooter tires that would be the equivalent of a 16" bicycle tire?

AW, that's an interesting idea, but how strong is it? Would you run 3000 watts through it? :lol: Wouldn't filling in the gashes with a tig welder and aluminum fill rod be as strong or stronger than the aluminum was originally? I'm no welder, but I've seen it done on shows several times. LH7X4BFrVtQ

I'm not saying you are on the wrong track here though. I built a bike specifically designed to climb the rocky mountains on 1200w of max power measured going into the controller. 22 amps controller, 14s battery, or commonly called 52v. My goal was to reach a max speed of no more than 20 mph, and be...

Just found this on Craigslist in my area. Its a 1997 GT-LTS-3 which has apparently had many parts upgraded. It looks exactly like what I am looking for in terms of suspension. I can easily fit a 20ah triangle battery in there. It has caliper V-brakes unfortunately, and I wanted disc brakes but I gu...

Glad you're enjoying the new tires! As I've been getting used to the trails around me, I've been trying out more off roading for something new, and I would like to do more. Just curious with those 2.4" tires, do you happen to know the inside with of your wheel/rim? The only 2.4" tire I hav...

The balance wire between 10 and 11 has a problem?

Ah, got it. Forgot to say I had the same problem with the paper thin sidewalls on my 20" Smart Sam requiring more pressure than I thought to corner on pavement.

Took me a while to choose the Crazy Bobs, but after riding them for a while, I'm definitely going with something else next. I've thought about the Marathon, but I'm leaning toward better offroad traction now. I replaced my rear tire with the old Forte knobby I was using before so I could get my bik...

Oh good, I'm glad the battery turned out as requested! Man, those are some nice views, and the power available sounds great! I do use the Marathon MTB tire on my wife's bike (with puncture resistant tubes on all bikes), and not only did it give me the impression of being quite puncture resistant, bu...

Good luck! I'm guessing it didn't arrive yet? Personally, if I had to work with a pre-built battery, I'd swap out the BMS for a smart bluetooth one anyway, so I can monitor cell group voltages.

Just to ease your worries,

I was going about 25mph late to ge...

Great work! Did you encounter any unexpected difficulties, such as flat tires? What parts of the trip did you like best? Would you rather be on a road that's straight or curvy? Also in the video I sometimes saw you cranking pretty fast in low gear going uphill, when I would have expected more motor ...

Very nice work!

Uma was my first thought when I saw this thread. Thanks for digging up that data!

I suppose a better way to think of the LVC is just like the charger does Constant Current, then Constant Voltage while charging the battery. The motor controller discharges the battery at a constant current until the LVC, then it discharges at a constant voltage.

I'd say go for it. I know from measuring my hub's hall sensors that each of the 3 wires just cycles between 5 and 0 volts. If you can measure that coming out of the sensor, then you're golden.
