Détails du produit

You should already be comfortable with LiFePO4 battery assembly, polarity checks, BMS wiring requirements and correct terminal tightening. Suitable tools and test equipment are required.

Before purchase, contact AmpBird to confirm the assembly documentation available for this configuration. Use the applicable component instructions and a verified wiring diagram during the build.

Any assembled-product photos show the intended finished appearance. The kit is supplied unassembled, and any battery cells shown are for illustration only.

Is This the Right Kit for You?

This kit is a good fit if you:

  • Want an economical enclosure package for compatible 280–314Ah cells.
  • Prefer sourcing the main enclosure and control components together.
  • Have the experience and tools to assemble and check a battery.
  • Want to understand the internal layout and take an active role in the build.

If you expect a ready-to-use battery or a box with the internal wiring already completed, this fully unassembled version will require more work than you are looking for.

Factory-Assembled with 314Ah Cells

These photos show batteries assembled with 314Ah LiFePO4 cells undergoing testing at the factory, offering a closer look at the internal layout, wiring and completed units. Prefer a ready-assembled option? We can also supply a fully assembled battery, saving you the work of installing the cells and wiring the components yourself. Contact us for configuration and delivery options.

Photos show assembled batteries with cells installed. Battery cells are not included with the DIY kit.



Pourquoi construire avec AmpBird

Tout ce qu'il faut pour un kit de bricolage sûr et fiable.

Kit de bricolage complet

Comprend le BMS, les jeux de barres, la visserie des bornes, le câblage et les composants d'assemblage essentiels. Les cellules LiFePO₄ de grade A peuvent être achetées séparément auprès d'AmpBird.

Cellules appariées de grade A

Nous proposons des cellules testées en capacité et appariées en tension par lot, afin que votre batterie s'équilibre plus rapidement et dure plus longtemps.

GTB préprogrammée

Le BMS inclus est livré configuré selon le nombre de cellules et la chimie de votre batterie. Pas besoin d'ordinateur portable ni de devinettes sur les paramètres.

Enregistrer ou prédéfini

Assembler votre propre pack coûte nettement moins cher par kWh qu'une batterie finie, à cellules de grade A identiques.

Capacité personnalisée

Choisissez le nombre de cellules et la configuration pour obtenir exactement la tension et les kWh dont votre système a besoin.

Documentation complète de la construction

Guide d'assemblage étape par étape, schémas de câblage et couples de serrage inclus. Assistance disponible en cas de difficulté.

QUESTIONS & ANSWERS

Frequently Asked Questions

Does this kit include battery cells?
No. Battery cells are purchased separately. The kit supports compatible 280–314Ah prismatic LiFePO4 cells in a 16S configuration.
Does the kit arrive pre-assembled?
No. You must assemble the enclosure, install the components, complete the wiring and configure the BMS. Relevant battery assembly experience and suitable tools are required.
Are cell busbars and epoxy insulation sheets included?
No. Neither is included with the standalone kit. Cell busbars are supplied when you purchase battery cells from AmpBird. Please confirm that the connectors match your selected cells and the kit’s layout.
Can I build a battery using 314Ah cells?
Yes. Using 16 compatible 3.2V 314Ah cells gives a nominal 51.2V 314Ah configuration with approximately 16.08kWh of nominal energy. Cells are not included, and usable energy depends on the completed system.
Will my existing cells fit?
Compatibility depends on cell dimensions and terminal layout, not capacity alone. Send us your cell model and terminal photo before ordering if you need fit confirmation.
What cables are included?
The kit includes four short 35mm² red and black internal power cables with fitted lugs. External battery-to-inverter cables are not included.
Does the 200A BMS mean the completed battery can continuously deliver 200A?
No. The BMS rating is a component specification. The completed battery’s operating limit also depends on the cells, cables, connections, protection devices and thermal conditions.
Will the BMS communicate with my inverter?
Please provide the exact inverter brand and model before ordering. Electrical suitability and BMS communication compatibility need to be checked separately.
Can I buy the kit and cells together?
Yes. Send us your preferred cell model, inverter model and delivery country so we can help confirm the combination and identify any additional materials required.
