Description
CATL 314Ah 16 Cell + BMS Bundle for 51.2V DIY LiFePO4 Batteries
This CATL 314Ah x 16 bundle is a serious foundation for a high-capacity 48V LiFePO4 battery build. With sixteen 3.2V cells connected in series, the bundle is designed around a 51.2V nominal pack voltage and approximately 16.08kWh of nominal stored energy.
It is a practical choice for customers who want to build a large DIY lithium battery for solar storage, off-grid power, backup systems, sheds, workshops, farms, caravans, marine systems or a 48V inverter installation where cell quality and a correctly matched BMS matter.
Why choose this CATL bundle?
CATL is one of the best-known names in lithium battery manufacturing, with major work across electric vehicles and energy storage. For a DIY battery buyer, the appeal is simple: this bundle gives you genuine A-grade CATL LiFePO4 cells in the right quantity for a full 16S 48V battery, plus the core protection hardware needed to manage the pack.
The included 200A BMS with a 3A active balancer is especially important for a 314Ah cell build. Large cells store a lot of energy, so a weak balancing system can take a long time to correct cell drift. Active balancing gives the pack a much better chance of staying even over time when the battery is assembled, configured and charged correctly.
What is included
- 16 x genuine A-grade CATL 314Ah LiFePO4 prismatic cells
- 1 x 51.2V 200A BMS with 3A active balancer
- 1 x 250A circuit breaker, DC PV 500V rated
- 2 x 35mm² / 2AWG 750mm copper flex battery cables, orange and black
Built for a 51.2V / 16kWh battery
A 16-cell LiFePO4 battery is the standard layout for many 48V solar and off-grid systems. The numbers are simple:
| Layout | Calculation | Result |
|---|---|---|
| Nominal voltage | 16 cells x 3.2V | 51.2V |
| Nominal capacity | 314Ah | 314Ah pack capacity |
| Nominal energy | 51.2V x 314Ah | About 16.08kWh |
That makes this bundle a strong option for a single large 48V battery bank, or as part of a larger expandable battery system where multiple 16S packs are installed in parallel with the correct protection and inverter settings.
Good fit for
- 48V solar battery storage
- Off-grid homes, sheds and workshops
- Backup power systems
- Large caravan, marine and mobile power builds where weight and layout are carefully planned
- DIY battery builders who want CATL cells rather than a ready-made sealed battery
What you still need to plan
This is a DIY battery bundle, not a finished plug-and-play battery. Before ordering, plan the enclosure, compression or mounting system, busbars, main fusing, disconnects, cable sizing, inverter compatibility, charger settings and final battery layout. If you are unsure, contact us before ordering so we can help confirm whether this bundle suits your system.
The BMS, breaker and cables included in the bundle are important parts of the build, but the finished battery still needs to be assembled safely and configured to suit your inverter, charger and installation environment.
Special order from China
This CATL bundle is a special-order product shipped from China. Estimated delivery time is normally 6-8 weeks. If you need a faster local option, we recommend comparing it with our EVE MB31 314Ah bundle, which may be the better choice when lead time is more important than choosing CATL specifically.
