UK Blackout & Field Application
If the internal BMS circuit board inside a sealed consumer power station fails in Year 4, the entire £1,500 battery is bricked. By building your own 12.8V 280Ah (3.58kWh) bank with individual EVE LF280K prismatic cells and keeping the included Spare JK BMS on the shelf, you can swap a failed BMS or bypass a cell in 15 minutes with a 10mm spanner.
Engineered for Both across Great Britain. In a prolonged utility outage, DIY Serviceable 12.8V 280Ah (3.58kWh) Prismatic LiFePO4 Builder's Pack (4× Grade-A EVE LF280K Cells + 200A JK Active-Balance BMS + Spare BMS) provides dependable off-grid capability backed by our UK warehouse support and plain-English commissioning documentation. Every unit is inspected prior to dispatch with an estimated UK delivery window of 48h.
