Then you need to either sell the current controller you already have and buy a controller with a temperature sensor, or convert the controller you have. I dont keep up on Sabvoton controllers, but you sure you can convert a non temp sens cont to a temp sens? If that be the case, then someone needs t...

So would it be correct to say that when my ca says 68 max amps, that means there was 68 battery amps?

Cant really measure phase amps anyways can ya.

And in other forums before us.

They must be listening. We discussed it here first.

Ah yes, the wonders of the english language. Though I did mess up that sentence. And that last one too. Definitely so. :wink: Not Defiantly so :lol: Definitely and defiantly are both adverbs, but trust us: the similarities end there. You use definitely when you want to describe something clearly, un...

Check out the new 2-ply Schwalbe Pick-Up, similar to the Kenda Kwick Drumlin Cargo but I'd obviously trust Schwalbe over Kenda, and it's available in 27.5".
Rated 5/6 for road grip and 6/6 for protection.

Temp sensor wire in the motor is easy to do.

Wiring temp thermistor - https://youtu.be/Wc8OJtFRUng?t=789
*Be sure you have the right thermistor for your controller.

I'd try to layer each 0.12 pure nickel strip or 0.15 nickel plated steel strip
welding each layer onto the next

or solder on some solid core wiring onto the strips.

I think a QS205 has 50mm magnets

The QS205 has many different heights of magnets with lots of difference wattage ratings.
55H/50H/45H from 1500W - 4000W there might be one listed as 5000W.

I like these, but not the most durable, XT90.

SB's are good and durable.

Yeah sorry, you got a lot going on. 2wd bafang hub motors and the chain motors. Good luck with that, Besttech Power would fit high quality but some have said their not. I need to look for high quality BMSs I dont know if you can do 15-20 minute charge every 40-50 miles on a simple 115V 10A outlet. L...

Thanks, I gave qulbix a holler and they do still sell it off-list. About $120 for the pegs and adapters (likely plus a bit more for shipping). Couldn't find a direct order source for the serrated washers, though -- but belleville has a website I could reach out to. Any fastener store should have th...

Those high power brushless chain drives are like bucking broncos unless I get a really expensive programable controller. Even with a cheap generic controller the big power motors are pretty good, so not sure where you get the bucking bronco idea from. Its better to have a single powerful hub motor ...

I like more charge amps, but I also look at the C-rate for charging. My laptop chargers were 5S (19V) in reality 20.50V so 0.50V off max charge, but at 8A. To add to that I had two batteries both 5S that I put in series with a home made XT90 series harness so I could disconnect 10S into 2x5S, and us...

Sleep expert Matthew Walker talks about what lack of sleep does and the health impacts. The particular video I watched last night was a Google Talks - https://www.youtube.com/watch?v=c1yGw_hfEfk
Saying the same lines in every video he is in.

Caused by government allowing the standard diet to happen and government being paid off by corporate lobbyists. Another interesting fact, when time changes occur and people lose an hour of sleep there are more car crashes and hospital stays. 25% more. And when people gain an hour, its 25% less one s...

Its short circuited

Remaining battery voltages is very hard to measure, then you pu tinto the mix cheap displays.

Display is erratic, thats why you take a digital multi meter and measure to confirm 0V.

Tab strips are super easy to bend and break, probably takes about 3 or 4 complete folds to break Same goes for solid core wire Stranded wire is good for flexibility why would stranded copper be less likely to break than strip? they both in theory should have the same fatigue limit if the same thickn...

That looks like a bunch of fun to ride on an ebike.

Still sitting at 10.5" for the season. The hills are looking about as green as they're going to get right now. It will be all brown pretty soon.

Who sez?

Soldering does take skill but theres no magic to it, only thing is it just takes practice and a little bit of technique. But you need the right tools, not the cheapest tools you can find, and not the cheapest solder neither. Adjusting the soldering iron to the right temperature for the work to do. L...

Maybe Rebel Wilson or Melissa McCarthy fell off their bed and caused the The Golden State to quake.

Why bother? Doing the work that they would have to pay others to do. Putting together a Think Tank on coming up with names. Funny thing is, the name is probably for a high school homework assignment which is due soon. Well I guess I shouldnt post a post like this but oh well, I hate to drag it down ...
