Optimising Battery Packs for Laser Rangefinders: Custom Lithium Solutions for OEMs

Laser rangefinders — used in surveying, construction, golfing, forestry and hunting — place high demands on compact power delivery.
For OEMs developing rangefinder devices, a key differentiator is the battery pack: small-size, high-energy, fast-charge capable, and ruggedized.
In this post we explore why custom lithium battery solutions are ideal for laser rangefinders, what design considerations apply, and how to work with a specialist such as PKNERGY to execute.

🔋 Why Custom Lithium Battery for Laser Rangefinder

Many existing rangefinders still rely on disposable CR2 or CR123A cells (e.g., the CR2 3 V lithium battery for golf rangefinders).
These limit runtime, increase user-maintenance, and generate waste.

A custom lithium-ion or lithium-polymer pack lets OEMs offer rechargeable devices with higher performance and better end-user convenience:

  • ⚡ High instantaneous current draw: Rangefinders pulse the laser and sensor electronics, requiring high peak current without voltage sag.
  • 📦 Compact and lightweight design: Users expect pocket-sized devices — especially in golf and sports markets — making battery packaging a major differentiator.
  • 🔌 Rechargeability and fast charging: Rapid USB-C charging enhances product lifecycle and professional usability.

⚙️ Key Customisation Requirements for Rangefinder Battery Pack

  • 🔋 Voltage configuration: Most devices operate at 3.0V (single cell) or 7.4V (2S). Capacities from 800 mAh to 2,000 mAh are typical.
  • 🔌 Connector & protection: Integrated BMS/PCM circuits prevent over-charge and over-discharge, compatible with USB-C or proprietary connectors.
  • 📐 Form factor adaptation: Slim or curved pack shapes to fit housing seamlessly.
  • 🌡️ Temperature resilience: Must withstand -10°C to +50°C; outdoor and industrial models may require IP54–IP67 protection.
  • ⚖️ Weight optimisation: Reducing battery weight by 10–20g significantly improves handheld comfort.
  • 🧰 Serviceability: Some high-end devices feature swappable batteries for convenience.

📊 Use-Case Example & Market Perspective

For a professional forestry survey instrument, shifting from disposable CR2 to a 3.7V 1,500mAh custom lithium-polymer pack reduced battery replacements by 80% and improved sensor performance at low temperatures.
In the golfing sector, the success of replacement lithium packs (like ZEUS rangefinder batteries) proves the aftermarket demand and margin potential.
