What this video covers
Maintenance on a LiFePO4 EVE battery bank involves replacing rigid factory busbars with flexible copper alternatives to accommodate potential cell swelling and prevent terminal stress.1:06 During the upgrade, the owner removes the batteries one at a time to maintain continuous power to the boat's systems.2:03 The installation process requires careful handling of alternator temperature sensors and BMS connections.2:34 After installing the flexible busbars, the owner reconfigures the BMS settings via the XiaoXiang app to enable active cell balancing starting at 3.30V, rather than only during the charging phase.10:40 This adjustment aims to maintain tighter voltage parity across the cells. Post-installation testing confirms that the new busbars resolve previous minor voltage discrepancies between the two battery units.28:59 The owner reports that after 20 months of operation, the cells remain stable with only 50–60 mV of variance under inverter load.30:54 Future plans include installing an external 5A active balancer to further refine cell balancing at high states of charge.31:08
