Huge shoutout to @Namasaki for being patient and and answering my questions.
Original Post: High Power 10s Lipo Battery Pack with BMS
My board: Frankenstein 1st Build
So, I’ve got the battery system wired up (5x2s 5300mAH 65C) and hardwired together. My BMS is set and ready for install. My Ollin VESC is also set (I haven’t set it up yet with BDLC). I wanted to post up what I’ll be doing and get the “green-light” from the experts before I start cutting and soldering.
I’m following “this” diagram, but having a hard time understanding it.
I’ll need to cut the XT90 switch off the VESC.
Step 1: The black wire from battery one is going to B-. Soldering on. A second black wire is being soldered from P- to the black wire of the VESC. I’ll need to create a connection through hardwired/banana connection.
Step 2: The red wire from battery 5 is being soldered directly to the VESC (also the red wire). I need to split this wire to the charge port. Which then get’s hardwired to C-.
Step 3: Hardwire the balance wires directly to the wires from the BMS. The balance wire has three colors (red, blue, and black,) the extension has black, black, and red.
Do I just need to trace the black wire from the battery to the corresponding black wire on the extension, and then exclude it from the soldering?
Step 4: How exactly do I need to wire the charge port to the bms?
For right now, I think I’ll have enough on my plate.
