Individual cells only by exception.
We build our batteries from EVE grade A prismatic LiFePO₄ cells. We sell the cells on their own only in exceptional cases — we would much rather build you a finished battery from them.
Why we prefer a complete battery
With a finished battery we know the cells are protected by a correctly configured BMS with a balancer and that they operate within the limits they are designed for. We also test the battery before dispatch.
With individual cells we have no control over how they will be connected and operated. A missing or badly configured BMS, unbalanced cells or excessive current can damage them irreversibly — and we do not want that.
If you still need cells for your own project, write to us. We assess each sale individually and agree on price, availability and terms. If we reach an agreement, we select the cells by measured capacity and internal resistance so that they match as closely as possible.
Need a battery in a different shape or size from those in our catalogue? Tell us what you need — we will assess whether we can build it for you.

EVE grade A.
We measure every cell — both capacity and internal resistance. Within one battery we combine cells with the smallest possible spread.
| Cell | Nominal capacity | Measured | Cycle life | Where we use it |
|---|---|---|---|---|
| EVE MB31 | 314 Ah | 330 Ah and more | 8,000 cycles to 70% capacity | 320 and 640 Ah batteries — BK4, BK8, BK15, BK16, 12VBK8 |
| EVE LF280K | 280 Ah | 300 Ah and more | 8,000 cycles to 70% capacity | 290 Ah batteries — BK36, BK72, BK1360, BK1450 |
| EVE LF105K | 105 Ah | — | 4,000 cycles to 80% capacity | Compact 100–105 Ah batteries — BK131, BK262, BK5, BK525 |
How we handle the cells from goods-in to the final test is described on the How we build page.
Tell us what you are building.
Describe your project — voltage, capacity, currents and available space. We will design a finished battery, or we can agree on cells.
