So is there anyway to boost output amperage without screwing around with the Volvo module?

I guess Volvo is saying that you can never jump start the car, or another car from yours, or add any accessories of any kind, that connect to the battery. Ridiculous.
If you add a 50 amp Anderson plug at the rear, and wire it to the battery with #6 plus and minus wires, with a circuit breaker next to the battery, the charging system will not be affected. Disconnecting the battery, while it is under load and the car running can hurt the electronics, but not adding a load.
An Anderson plug at the rear bumper is the best way to add more power to your trailer. It will aggressively charge the trailer battery and carry a much heavier load than the small charging wire in the seven pin plug.
Then, you'll have a second pigtail that goes directly to the trailer battery and gets plugged in at the same time as the regular pigtail. It can also be used to plug a portable
solar system into the trailer. Or pull 12 volts directly from the trailer battery to run a tool, or electric tongue jack. Or plug a
solar system into the tow vehicle to charge its battery. A very useful addition.
