Dan and Kika install a 50kWh lithium battery bank to power the electric motors and house loads on their sailboat.0:23 They construct custom battery combiner boards to manage five batteries per bank, utilizing Class T fuses on each battery to protect individual conductors.1:51 To handle high current loads, they run dual positive and dual negative cables from the combiner boards to the BMS, splitting the load equally between conductors.2:10 During the installation, they realize the cable geometry for the second battery bank requires a symmetrical layout to ensure proper reach and cable management, forcing them to remove and rotate the batteries to mirror the first bank.25:24 After wiring the system, they use Victron components to monitor the setup and successfully power up the BMS and system displays.32:06 The project concludes with the initial testing of the electric motor circuit.34:05 Proper planning of cable runs and maintaining symmetry in battery bank configuration prevents installation errors and simplifies complex high-amperage wiring.
