Build a 14.3kWh Battery with 16 CATL 280Ah Cells
The CATL 280Ah cell is well suited to customers building practical medium-to-large LiFePO4 energy storage systems.
A typical 16S configuration provides:
| Configuration | Nominal Voltage | Capacity | Nominal Energy |
|---|---|---|---|
| 4 Cells / 4S | 12.8V | 280Ah | 3.58kWh |
| 8 Cells / 8S | 25.6V | 280Ah | 7.17kWh |
| 16 Cells / 16S | 51.2V | 280Ah | 14.34kWh |
For home solar storage and off-grid applications, a 16S configuration provides a convenient foundation for building a 51.2V battery system.

Checked Before Shipment
We understand that cell consistency matters when building a LiFePO4 battery pack. Before dispatch, cells are checked to help reduce avoidable problems during assembly.
| Check | What We Check |
|---|---|
| Voltage Check | Open-circuit voltage consistency |
| IR Check | Internal resistance consistency |
| Capacity Test | Available for matched sets and project orders |
| Visual Check | Cell casing, terminals and QR codes |
| Packing Check | Protection before dispatch |
Capacity testing is available for matched sets and project orders.
If you have specific matching or testing requirements, please contact us before placing your order.
