Custom	Per specification	Any series × parallel	OEM/ODM projects

Core Advantages

High Safety & Stable Quality: NiMH chemistry is non-flammable and environmentally friendly. Each pack undergoes charge-discharge cycling, voltage testing and insulation testing before shipment.
Wide Temperature Range: Charge at 0–45°C, discharge at −20–55°C — suitable for industrial and outdoor environments.
High Discharge Rate: Up to 2C continuous discharge, supporting power tools and high-drain devices.
Long Cycle Life: 1000+ charge-discharge cycles under normal use, reducing total cost of ownership.
Custom Connectors & PCM: JST, Molex, bare leads, custom harnesses; optional protection circuit module (PCM), NTC thermistor and fuel gauge.
Certifications: CE, RoHS, REACH, UN38.3, MSDS — safe for global air and sea shipping.
Fast OEM/ODM Service: Free sample evaluation within 7–10 days; mass production lead time 15–25 days. MOQ flexible for custom packs.
