We design and manufacture stable, reliable battery pack systems for demanding industrial and professional applications. Our solutions are built on high-performance 18650 lithium-ion cell platforms, combined with deeply integrated BMS, thermal monitoring, and structural engineering, to solve real-world challenges in high power output, long service life, and operational safety.
We do not sell individual cells. We deliver application-ready battery pack systems engineered to reduce field failures, simplify system integration, and support long-term product reliability.
Designed around high-performance industrial 18650 cell platforms
Optimized for applications where stable high current delivery matters. Continuous discharge capability is clearly defined, while short-duration high-power output is enabled through intelligent thermal monitoring—avoiding overstated or unsafe current claims.
Not just "robust," but designed to eliminate field failure risks. Our packs undergo application-oriented mechanical and environmental considerations to ensure stable operation under vibration, shock, and continuous-duty cycles—helping reduce warranty costs and protect your product reputation.
From early-stage prototyping to volume production, the same engineering team supports your project—minimizing miscommunication and redesign risk.
| Parameter | Specification |
|---|---|
| Nominal Capacity | ~3,000 mAh |
| Nominal Voltage | 3.6 V |
| Max Charge Voltage | 4.20 V |
| Standard Charge Condition | CC/CV, ~1.5 A |
| Rated Charge Condition* | CC/CV, ~4 A |
| Max Continuous Discharge | 15 A (without temperature cut) |
| Peak / High-Rate Discharge | Up to 30 A with pack-level thermal monitoring (recommended cut-off ~80 °C) |
| Discharge Cut-off Voltage | 2.5 V |
| Cycle Life (Cell Level)** | ≥250 cycles |

* Rated charge condition refers to a specific test condition used for rated capacity evaluation, not a universal recommended charging current.
** Cycle life reference: approx. 4A charge / 15A discharge, capacity ≥60% of standard capacity after 250 cycles. Pack-level lifecycle depends on BMS strategy, depth of discharge, and operating conditions.
Recommended Configuration: 5S2P (18V / 6.0Ah)
Key Value: Delivers instant high torque with stable power output, supporting continuous operation without performance drop.
Recommended Configuration: 6S3P (21.6V / 9.0Ah)
Key Value: Designed for 24/7 charge-discharge cycles with enhanced safety for unattended operation environments.
Recommended Configuration: 10S4P (36V / 12.0Ah)
Key Value: Balances high power demand with long runtime, supporting stable system-level voltage under load.
