What this video covers

Lithium-ion phosphate batteries from the brand LiTime offer a lower-cost alternative to premium brands like Battle Born for sailboat and vehicle house banks. A 300 amp-hour LiTime battery costs approximately $740, compared to the $2,200 required for an equivalent capacity in Battle Born units. Two 300 amp-hour LiTime units were purchased for a box truck build, totalling 600 amp-hours of capacity. Upon arrival, both batteries measured 13.17 volts, consistent with shipping regulations requiring partial charge. Installation requires charging each unit separately before connecting them in parallel to ensure the internal battery management systems synchronise correctly. The setup utilises two Victron 100-50 MPPT controllers paired with 1,700 watts of solar panels. Initial observations indicate high-quality construction, clear documentation, and responsive customer support. Long-term performance testing under heavy loads, including air conditioning, is planned for an upcoming road trip to the Annapolis Boat Show.
