LiFePO4 12V 100Ah Humsienk battery, review and test, increasing the capacity of Ecoflow Delta 2

Опубликовано 17 февраля 2026, 18:56

In this video I will share my experience of implementing a case of doubling the usable capacity of the Ecoflow Delta 2 charging station — using an external 1280 Watt-hour LiFePO4 Humsienk battery. This allowed me to save about 70% of the amount I would have had to spend on purchasing the original additional battery while achieving the same result.
Here you will see — an overview of the Smart BMS functionality of the battery, a real capacity test, the method of connection and joint operation with Ecoflow Delta 2, and the creation of logic in Home Assistant to turn battery charging on and off.
