Why Cell Selection Matters
The cornerstone of delivering high-performance custom battery solutions
Quality Begins at the Core
The performance, safety, and lifespan of any lithium battery pack begins with the quality and suitability of its core component: the cell.
At Large Power, our cell selection process is not just a procurement task — it’s a critical engineering decision rooted in deep expertise.
As a trusted battery pack manufacturer and lithium cell factory, we follow a meticulous, time-tested process to ensure every battery we build starts with the safest and most reliable cells.
Our Comprehensive Cell Selection Process
A meticulous approach to ensure safety, performance, and reliability
Rigorous Cell Selection Process
As a battery manufacturer, we implement strict internal standards to evaluate and select lithium cells. Each year, we test multiple cell types for safety, consistency, and performance to ensure every battery starts with reliable, high-quality components.
Tailored Cell Matching
With access to a wide range of cell formats and chemistries — from NMC to LFP — we make data-driven decisions to match the optimal cell type with your specific application requirements.
Brand and Budget Flexibility
We provide tailored battery solutions based on the customer’s application, performance needs, and budget. By selecting the most suitable cells from our qualified supply chain, we help clients achieve the best balance between cost and performance—without compromising quality.
In-House Cell Testing
Every selected cell undergoes rigorous in-house validation in our quality lab. From capacity grading to thermal behavior testing, we ensure each cell meets our stringent standards before integration into any pack.
