Thanks everyone. I am all kitted out with 4awg wire, 175amp anderson plugs, two 50amp blue sea breakers, and two 150ah batteries for 300ah LiFePO4 storage total. I also added a 1000watt inverter with a 150amp blue sea breaker. I am planning on adding a vent similar to the vent that covers the IOTA to the interior battery box wall the give even more ventilation (it has small circular vents to the tiedown area, but id like the interior wall to also have venitalation). I've also installed a temperature monitor so I can monitor battery box temp from the truck drivers seat for longer drives where the Victron may get hot. If temperature is a constant issue I will add a barrel latch to keep the battery box hatch open during drives.
So far, so good. The existing Zamp PWM controller + 160 watt panel tops off the batteries to around 98%. The Victron 30amp DCtoDC charges the batteries FAST. Both batteries were at 80% and after a run to the grocery store both batteries were topped off. Inverter charges phone, laptop, and runs Starlink router without kicking the internal fan on.
