606090 7.4V 4000mAh LiPo Battery

Product Overview

The 606090 7.4V 4000mAh 2S LiPo Battery Pack is a high-voltage, high-capacity rechargeable lithium polymer battery pack built for demanding portable applications. By connecting two 3.7V/2000mAh cells in series (2S configuration), it delivers a stable 7.4V nominal output with 29.6Wh energy — making it an ideal power source for GPS tracking systems, portable power banks, handheld industrial terminals, RC equipment, and field communication devices.

Every pack is assembled with matched-capacity cells, precision spot-welded connections, and integrated PCM protection to ensure consistent performance, long service life, and safe operation across the full charge/discharge cycle.

Key Features

• ✅ 7.4V 2S Configuration – Series-connected dual-cell design for devices requiring higher voltage rails
• ✅ 4000mAh / 29.6Wh High Capacity – Extended runtime for power-intensive field and portable applications
• ✅ Matched Cell Assembly – Cells sorted by capacity and internal resistance for balanced charge/discharge
• ✅ Integrated PCM Protection – Overcharge, over-discharge, overcurrent, short-circuit & cell balancing protection
• ✅ Stable Discharge Curve – Consistent voltage output from full charge to cut-off
• ✅ 500+ Cycle Life – ≥80% capacity retention after 500 full charge/discharge cycles
• ✅ Low Self-Discharge – ≤3% per month, ideal for GPS trackers and standby-mode devices
• ✅ CE & UN38.3 Certified – Air freight compliant, meets EU and global market requirements
• ✅ OEM/ODM Ready – Custom voltage, capacity, form factor, connector & labeling available
