I think I’ve got the basic layout of my setup, but I have a question or two and just want an extra set of eyes double-checking what I’m thinking.
Let me make one thing clear before beginning, so as to remove some confusion/complexity from the conversation. I know there are two schools of thought regarding a BMS (Battery Murdering System?). I’m using brand new, high quality batteries. I’m never going to charge up to 4.2 volts nor drain past about 3.6 volts. I’m not going to use a BMS. I’m aware of the various possible issues, but that’s my choice.
(Second picture down is a little closer up shot.)
So, battery on the right outputs into an on/off switch. Where I solder the connector to the on/off switch input (loose in photo), I’ll also add a small set of wires going to the XLR connector for charging the battery pack.
Output from the on/off switch (loose connector shown in photo) will feed into a splitter which will distribute the power to 2 VESCs. I’ll wire the white wire from my voltage indicator into that hot battery wire (red) when I add the connector so that when I turn on the power switch, I’ll get a voltage indicated. The red for the voltage indicator will get 3.3V or 5V from a VESC and I guess its black can go to the other battery wire or to a GND on the VESC (I’d like feedback/confirmation on that).
The 2 VESCs will plug into the splitter for power and the motors will plug into the VESCs. told me that any of the three wires from the motors (black/blue/yellow) can plug into any of the three black bullet connectors coming out of the VESC. That seems odd to me. Any feedback?
I ended up with several male-to-mail connectors (for some reason). I think I’ll use one of them to connect the red (and maybe black) to a 3.3V or 5V and a GND from a VESC to power the voltage indicator.
The CAN bus connector will plug into both VESCs so they can coordinate. I believe it plugs into the white connector in the center at the top. They both have 4 pins.
For some reason, I have 2 VESC sensor wires. I don’t think I need them. The motors have sensor wires coming out of them. I think they will plug in to the white connector in the upper left, underneath the large, red wire.
I believe the two white connectors at the bottom of the VESC (6 pins each) are unused. They have available 3.3V, 5V, and GND. That’s where I thought I might plug in the male-to-mail connector for the voltage indicator.
How does the receiver hook into a VESC? I think I’m missing the wire for that.
Although I have a few gaps to fill in (with assistance from you all!), I think I’ve covered all the components and connections.
