Do we really need a pre-charge system for our DIY battery banks?

Let's find out...

Today we are going to simulate a large battery bank and a high input capacitance load like an inverter to figure out whats really going on and have a better understanding to answer this question. This basically applies to any DC/AC inverter (or other high capacitance load that allows heavy inrush currents) and high capacity battery banks, no matter if you use a diyBMS, Batrium, REC-BMS that use an external DC contactor or a Seplos, JBD/Overkill/Daly/JK-BMS or any other that uses MOSFETs for load/charge switching.
