About the Felicity Solar FLA12280-EU 12.8V 3.6kWh Battery

The Felicity Solar FLA12280-EU is a 12.8V LiFePO4 battery holding 3.6kWh of nominal energy, rated for a continuous 1,875W of charge or discharge and 2,500W for 15 seconds, with a depth of discharge of ≥95% and a cycle life of ≥6,000 cycles. Charging is capped at 14.4V and 150A, and the operating window runs 11.2-14.4V. Peak charge or discharge current reaches 200A for 15 seconds. Sixteen FLA12280-EU units wire in parallel for 57.6kWh, so the bank grows with the load instead of being replaced. Note that the ≥95% depth of discharge, not the 3.6kWh nominal figure on its own, is what governs how much energy you can actually draw. Each unit weighs 26kg net and measures 379×241×286mm, in an enclosure rated IP21. We are an authorised Felicity Solar distributor, and the FLA12280-EU is covered by a 5 Years warranty.

Frequently Asked Questions

How much energy does the FLA12280-EU hold?

3.6kWh of nominal energy on a 12.8V LiFePO4 bus. The separate depth-of-discharge rating of ≥95% is what governs how much of that 3.6kWh is available to draw, so read the two figures together rather than treating the 3.6kWh as usable energy.

How much power can the FLA12280-EU deliver?

1,875W of continuous charge or discharge, rising to 2,500W for 15 seconds. Peak charge and discharge current is 200A over that same 15-second window, and the maximum charge current is 150A.

Can FLA12280-EU batteries be connected in parallel?

Up to 16 units in parallel, giving 57.6kWh. Each unit is 26kg net and measures 379×241×286mm, so size the shelf or rack for the full bank before you expand it.

What warranty and cycle life does the FLA12280-EU carry?

5 Years warranty, alongside a cycle life rated at ≥6,000 cycles. Charging is limited to 14.4V and 150A, the operating voltage window is 11.2-14.4V, and the enclosure is rated IP21.
