Pin 2 / VBATT does not specify a current limit while Pin 9 / 12V does.
Both pins utilize Pin 10 as Ground. Without a limitation on Pin 2, the connector current limit of 6A may be exceeded if Pin 2 / VBATT and Pin 9 / 12V pins are both utilized or if VBATT draws a current in excess of 6A alone.
Recommend limiting Pin 2 to 4A at battery cutoff voltage.
If the payload is a constant power device, as the battery voltage decreases the current will increase proportionally. Using a 1S battery example and a conservative cutoff.
4A @ 3.7 VDC = 14.8W,
14.8W / 3.0VDC = 4.9A.
