Model 5025100 7.4V 1500mAhlithium polymer battery. High energy density with built-in BMS protection. Ideal for robotics, medical devices and industrial equipment. Custom sizes available. HNF Battery manufacturer.
Overview
The 5025100 is a slim 2S1P lithium polymer battery pack delivering stable 7.4V / 1500mAh (11.1Wh) in an ultra-narrow 5.0 × 25 × 100mm form factor. Its distinctive thin-strip profile — just 5mm thick and 25mm wide — makes it uniquely suited for slim-chassis RC vehicles, narrow-body drones, robotic arms, handheld power tools, and any application where a standard flat pack is too wide to fit. Integrated BMS with cell balancing ensures safe, reliable performance across all 2S charging scenarios. Custom wire length and connector available as standard OEM service.

2S1P Configuration Explained
Cell 1 (3.7V / 750mAh) ──┐
├── Series → 7.4V / 1500mAh
Cell 2 (3.7V / 750mAh) ──┘
Total Voltage = 3.7V × 2 = 7.4V
Total Capacity = 1500mAh (single string)
Total Energy = 7.4V × 1.5Ah = 11.1Wh⚠️ Charging requirement: Must use a 2S-compatible balance charger set to 8.4V / 2S LiPo mode. Balance charging via JST-XH 3Pin connector is strongly recommended to maintain equal cell voltage and maximize pack lifespan.
5025100 Unique Form Factor Advantage
| Dimension | 5025100 | Standard 2S Pack |
|---|---|---|
| Thickness | 5.0mm | 8~12mm |
| Width | 25mm | 40~60mm |
| Length | 100mm | 60~80mm |
| Profile type | Ultra-slim strip | Standard flat |
| Ideal housing | Narrow tube / rail slot | Wide flat cavity |
📌 Why this matters: The 5.0 × 25mm cross-section fits into rail-mounted, cylindrical, or narrow-slot enclosures that are completely incompatible with standard flat LiPo packs — opening applications that no standard battery can serve.
