This is a Portable battery pack that we put together for demonstrations. We found this unused Bosch tool case that was just the right size for a Tesla Model S battery module with the BMS installed. It has a power switch on the outside which is connected to the BMS’s SW input, and the indicator light is connected to the 24v output (C- to B+). The output connector is a 120 amp Anderson connector mounted flush on the end, and we attached matching connectors to a suitable power inverter and charger.
This setup provides 3.6kwh of portable power that looks right at home on any job site.
That almost looks too good. Job VERY well done. 🙂
