Blacktip DPV Battery

If you don’t mind my asking, what BMS are you using for your pack? Been thinking about building one myself.

You can disable the blue wire in the firmware if you want. If I recall all it does is measure the balance between the two batteries. It does nothing else. The default value here is 14
Set $x to 0 in VESC Tools. If you don't connect blue wire and then set ($x) imbalance to zero then you'll always get full 4 bars on the display

See guide here: https://dive-xtras.zendesk.com/hc/e...310802094996/BlackTip_Pocket_Guide_v1.19F.pdf

Depending on what VESC controller you have I guess the newer ones dont come with a USB adapter so you'll need to connect your own micro-USB adapter to the VESC controller in the tail section. The older controllers had this included.

The scooter will run completely fine without it as mine as been turned off over a year. If you dont do this you'll get a imbalance error when the voltage eventually gets lower.

This is not my drawing (it was done by a friend of mine that built one of my batteries) but this is how you can setup the blue wire if you want the battery display to work otherwise you need to disable it in the firmware.

Just wanted to say thanks for posting this. Second time I've referenced to fix the battery imbalance issue. Thank you!
