Every cell in our battery system goes through strict testing after being activated and tested by the original manufacturer (e.g., EVE CATL CALB ). We don’t sample—we test every single cell.

Step 1: Capacity Grading (2 days)

Even within the same production batch, tiny variations in manufacturing cause subtle differences in capacity and internal resistance. Capacity matching identifies these differences and groups cells with closely matched parameters together, greatly improving the battery pack’s performance, cycle life, and safety. Each cell’s test data is recorded and linked to its unique ID (QR code), allowing full traceability. If a battery pack ever experiences issues, every cell’s production and capacity data can be traced for analysis.

Step 2: Aging Test (2 weeks)

New cells are chemically active and may hide tiny defects (like micro-shorts or impurities). Over time, these flaws reveal themselves as abnormal self-discharge. Aging tests:

1. Remove unstable cells,
2. Stabilize internal chemistry,
3. Improve long-term reliability.

The built-in battery cell is CALB A+

CALB originates from the China Aviation Industry Corporation, inheriting aviation-grade standards with a “zero-tolerance” approach to safety. In large-scale energy storage projects, safety is priority number one — without it, all other considerations are meaningless.

By inheriting the aviation industry system, CALB ensures rigorous quality control, precise manufacturing processes, and exceptional consistency, far beyond what typical consumer electronics battery manufacturers can achieve. This provides your project with the most fundamental and reliable safety baseline, greatly reducing potential risks.

CALB’s energy storage cells are designed for long cycle life, excellent consistency, and high energy efficiency. The company consistently ranks among the top three China suppliers for large-scale energy storage projects and serves as a core supplier for numerous national-level projects.

CALB is a long-term partner of top-tier energy enterprises including the State Grid, China Southern Power Grid, Huaneng, Huadian, and State Power Investment Corporation. Its products are widely used in both grid-side independent energy storage stations and power generation-side storage projects, ensuring reliable performance across diverse applications.

Triple-Safeguard 

 Tier 1 safeguards ： BMS with superior stability 

It precisely monitors every cell's voltage and charging/discharging currents (±10mV / ±1%!), providing instant protection against over/under-voltage, dangerous over-current (with smart limiting), and short circuits. 

Plus, intelligent cell balancing keeps your batteries healthier and lasting longer. All critical safety settings are adjustable.

 Tier 2 safeguards ：250A Air Circuit Breaker: Your Instant Firewall

Air circuit breakers use air as an arc extinguishing medium. When a circuit fails, they can quickly cut off the current and protect the circuit and equipment. Compared with other circuit breakers, they have higher breaking capacity and more precise adjustable parameters. Cuts Power in 0.1m (faster than a lightning strike!)

 Tier 2 safeguards ：Built-in fire extinguisher

In the event of prolonged overloads or a short circuit in the BMS or a cell, the built-in automatic fire-suppression system triggers to extinguish any ignition and protect users and property. It also responds to externally generated heat or nearby fires by activating at elevated temperatures to limit thermal runaway and minimize battery damage.

Compared to traditional agents, aerosol extinguishers work without oxygen (crucial for lithium battery thermal runaway), are non-conductive (won’t short circuits), penetrate deeply into battery cells, leave minimal residue, and react within seconds.
