High current solid state battery disconnect
Probably all those devices have to be mounted on a plate or heatsink. The heat generated due conduction loss is proportional to I²R, where R is the on resistance of the MOSFET. For large current it is better to put in parallel multiple MOSFETS that have a good thermal conduction to a PCB with thick copper layers.
A special charge pump is needed for driving N-MOSFETS. An example is an ideal diode controller like LTC4358
