Noob question thread! 2020_Summer

Shouldn’t blow up or anything, it just won’t go over 42v.

Then I am stumped. The charger could be bad or it’s just waiting to be connected to a pack before going to its full voltage.

Are you sure your meter is reading correctly? Most meters go crazy when the battery gets low.

I’ve got two meters,aAnd the one in the smart bms. I’m returning the charger, I have no idea if it’s broken or just a strange interaction between the bms and charger.

I found out that someone doesn’t use loopkeys. Just xt90s on the end of the battery as “switch”, is there reason why to do that instead of loopkeys?


vid:

That basically is a loopkey, just less refined.

so its equal safe as loopkey on positive wire?

a loopkey is just a fast way to physically disconnect the battery and esc, most people that uses under deck enclosure does not have wires running from battery to esc exposed, so a loopkey is made for that.

for mtb, most have top mount battery box and rear mount esc box, so there are wires running from middle to rear, and if u already have a connector there, then its already a loopkey in a sense

Yes, safety is equal. Function looks more difficult. Appearance, I’ll let you be the judge. Loopkey installations can appear anywhere from terrible to professional grade.

Yeah im not willing to take that risk. It feels like I lost “pulling” power. Before I switched to the new firmware and vesc tool, I had plenty, even at 30 mph and above

Which firmware did you have before?

Don’t remember the exact version. It would probably be one of the two versions before the current one.

This one’s for the vendors, I’m pretty much ready to set up shop for real, what platforms do you guys use for your web shops? Any pros and cons I should know about?
I would heavily prefer the ability to offer financing, I feel that would make sales come in a lot more frequently.

One of the biggest out there is Shopify

Woocommerce is another

You can build your site from a variety of different places. EditorX is good, Squarespace is good, there are others too tho

Thanks! I feel like a confused old man when I try and do any serious computer stuff lol. Making stuff? Sure, no problem. Starting any kind of web page? Daunting.

I’m having trouble making a change in VESC tool…

I installed a bigger battery, and most of the settings I want to change are accessible through the “Multi Settings” option:

After I make a change I can “Write to All VESCs”:

So for so good.

This setting however is accessible through the “regular” settings not the “Multi Settings”:

Instead of “Write to All VESCs” I only have “Write” and when I hit it, it only writes to the first VESC.

If I press that “CAN ->” button in the lower left, It detects “UNITY (LOCAL)” and “UNITY (70)” but if I try to select UNITY (70) the tool reboots and I get this:

Not sure what to do with this. Where is this pairing list and what is the UUID I should add to it? Is it 70?

Just built a battery and plugged in the BMS and charger, I’ve never used a smart Bluetooth fancy BMS before can someone help me figure out if I did this right?


I’ve got no collar pieces or nuts for this.

How do I get charging plug to stick in place?

What goop will hold this socket steady?

Why are circles so… Circle?

Is that a GX16?

If it is, PM me your address I have washers and nuts and can put some in a stamped envelope

But either way, with or without a nut, I would also epoxy it from the inside only. But a nut is strongly preferred

It’s a gx16 yeah but the part coming through to the inside of the enclosure is slightly tapered, I have plastic cable housing for it but it wont catch the threads. I also have some 16mm button nuts that won’t catch the threading either

Aww crap, I forgot you were in Canada. Things are not so simple LOL

I still have those pieces though but once you add international shipping, might as well hit up AliExpress or skip them altogether
