Connectors
From left to right, liquid cooling ports, HV connector, LV connector
HV connector
The main HV connector is an APTIV 35561611 RCS1200 SW F0T7-144-23 connector
There is also another HV connector on the back used for the DC fastcharging port. It has a separate HVIL loop.
Low voltage connector
LFP low voltage connector in stock on Mouser incase you are not able to get the harness with connector when you buy the battery. The connector has the pin numbering stamped on it.

Note on WUP
WakeUpPin (WUP) can be used to make the battery survive a reset/reboot in the software. If you connect all 4x 12V pins to WUP pin via a relay/SSR, you can perform graceful reboots, without needing to cycle 12V to the battery to get it to work after a reboot/OTA.
