What this video covers

The crew of Parlay Revival replaces their existing lithium battery bank with a 3,000-amp-hour Victron system while docked in Phuket, Thailand.4:02 The upgrade involves removing eight 270-amp-hour batteries and installing twelve Victron units configured into two separate banks, each with its own external battery management system (BMS) for redundancy.8:05 To ensure the two BMSs share the load accurately, the crew fabricates custom copper bus bars and ensures all cable runs from the batteries to the BMS and loads are identical in length.11:33 The installation follows ABYC standards, utilizing T-Class fuses within 7 inches of the positive terminals or sheathed cables for longer runs.14:31 A hydraulic lug crimper secures all connections, and a torque wrench ensures terminal integrity.15:19 The crew donates the removed batteries to a local community housing project managed by a charter operator, where the units will power a low-load, off-grid residential setup.18:13 Proper load balancing and cable length consistency are critical when paralleling multiple battery banks with independent BMS units.
