ASOL 102025 Lithium Polymer Battery — A high-rate 420mAh soft-pack Li-Po delivering 1.554Wh energy with a 3C discharge rate (1260mA peak). Compared to standard 1C batteries limited to 420mA, the 102025 delivers 3× more peak current for stable voltage under load — the ideal choice for Bluetooth trackers, key finders, wallet trackers, pet trackers, TWS earbuds charging cases, and voice recorders.
Why 3C vs Standard 1C — Discharge Rate Comparison
| Battery Type | Max Discharge Current | BT Tracker BLE Burst | TWS Case Charging | Voice Recorder Peak | Verdict |
|---|---|---|---|---|---|
| Standard 1C | 420mA | ⚠️ Marginal | ❌ Slow charge output | ❌ Too weak | Cannot sustain peak load |
| 102025 — 3C ★ | 1260mA | ✅ Stable advertising | ✅ Fast recharge cycle | ✅ Clean audio | Best choice |
Bluetooth trackers, TWS charging cases, and voice recorders all draw brief peak currents that exceed 1C ratings. The 102025’s 3C capability ensures stable BLE advertising power, fast earbuds recharging, and clean voice recording without voltage sag.
