Prolanv alternate connectors
Reasons for considering the new connectors (Thanks @echoGee):
- They have specific signal pings, for can bus, and the data that is needed for DS-015
- Can also do SMBUS with the same connector using the extra data pins, which are convenient for backward compatibility to non CAN-bus enabled autopilot/ companion computer/ Arduino etc
- Makes it easier to make the packs re-usable
- Makes it a little easier to handle oscillation, and have multiple batteries
- Lead time less than four weeks, for up to 50k qty
- Mechanical prevention of reverse plugging (since the previous one doesn’t have it right)
Questions from the call:
- Has anyone tried them: @echoGee has prototyped already a BMS system, but not flown.
- Any idea of MTBF of plugging?: @echoGee, “10000 MTBF for the new connector”
- Any dimension changes to the original connector: same width (similar), but taller
Alternatives to mandating the connector on the Standard from the discussion
- Maybe specify a connector as a suggestion
- Also specify the orientation to the connector relative to the pack
