- At which stage in the design cycle is the battery designed? (before/after motor selection, before/after full electrical system diagram)
- How to deal with/account for in-rush current?
- testing vs calculation
- battery placement within the system? - is this important?
- sourcing?
- Active vs Passive balancing?
- Copper wiring/Soldering
- Connectors
- Assembling the battery - how important to test each cell and specify each cells location based on resistance?
- Spot welding - worth it to make a pcb supercap thing for that?
- bms on the battery? or separated?
- hexagonal or square grid pattern?
- vertical stacking? - some one else advised against this, but it might be nice to have a flatter battery
- how to charge, with bms or without?
- What to expect during assembly?
- expected costs? cost savings?
