Big Capacity. Clean Power. Built for Makers & Builders.
The 103450 3.7V 2000mAh Lithium Polymer Battery is the go-to power solution for Bluetooth speakers, portable power banks, and creative DIY electronics projects. Combining high energy density, built-in PCM protection, and a slim, versatile form factor — it delivers the reliable, stable power that both consumer products and maker projects demand.
✅ Key Features
🔋 2000mAh High Capacity – Extended Runtime for Speakers & Power Banks Delivers robust, long-lasting power for energy-demanding portable devices. Keeps Bluetooth speakers playing longer, power banks charging more devices, and DIY projects running reliably — all from a compact, lightweight cell that won’t weigh down your build.
📐 Precision Slim Form Factor – 103450 (10 × 34 × 50mm) The ultra-slim 10mm profile and optimized 34×50mm footprint fit seamlessly into Bluetooth speaker enclosures, portable power bank housings, and custom DIY project builds — with minimal structural modification required, saving both time and development cost.
🛡️ Built-in PCM 4-in-1 Protection – Safe for DIY & Consumer Use High-performance Protection Circuit Module (PCM) provides four-layer defense against overcharge, over-discharge, overcurrent, and short circuit. Especially important for DIY applications — preventing overheating, swelling, or fire risk during development, testing, and daily use, giving makers and engineers complete peace of mind.
⚡ Stable Discharge Platform – Pure Power for Premium Audio Advanced polymer electrolyte system delivers a flat, stable discharge curve with minimal voltage fluctuation — eliminating background noise, audio distortion, and performance drops in Bluetooth speakers and amplifier circuits, ensuring a cleaner, richer sound experience from start to finish.
🔧 DIY-Friendly Design – Plug In & Build Slim soft-pack construction with standard wire leads and connector, compatible with popular charge/discharge control modules including TP4056 and common BMS boards. Ready to integrate into custom projects straight out of the box — lowering the barrier for hobbyists, makers, and prototype developers.
♻️ 500+ Cycle Life – Built to Last Rated for over 500 full charge/discharge cycles with ultra-low self-discharge rate. Retains excellent capacity after extended storage periods — reducing replacement frequency and delivering outstanding total value across the battery’s full lifespan.
