ENL-KNB47 7.4V 2000mAh Li-ion Two-way Radio Battery for NX-200 NX-300 TK-5220 TK-5320

The ENL-KNB47 replacement battery is fully compatible with the following Kenwood NEXEDGE and TK series two-way radio models:

✅ Direct Replacement for Kenwood KNB-47L
Engineered as a drop-in Li-ion replacement for OEM part KNB-47L, fully matching the voltage platform (7.4V) and form factor of the original battery, supporting radios NX-200, NX-300, TK-5220 and TK-5320 without any modification.

✅ Entry-Level Capacity with Stable Output
2000mAh nominal capacity provides reliable daily-shift operation for light to moderate communication workloads. Stable 7.4V output, low self-discharge rate, ideal cost-effective choice for fleet rotation.

✅ 5-Function Smart BMS Protection
Integrated circuit module delivers comprehensive safety: over current protection (OCP), over charge protection (OVP), over discharge protection (UVP), temperature sensor and reverse polarity protection. Effectively prevents overcharge, overheating and short circuit hazards.

• ⭐ Premium Li-ion Cells — Long cycle life (800-1000 cycles), low self-discharge rate, stable discharge curve for consistent signal transmission

• ⭐ High Impact ABS/PC Shell — Rugged composite housing, anti-drop, anti-vibration, suitable for harsh outdoor communication environments

• ⭐ Ultrasonic Welding Sealing — Reliable structural integrity, dustproof and moisture resistant for demanding field conditions

• ⭐ Golden Plated Brass Contacts — Low internal resistance, stable power & signal transmission, anti-oxidation for long service life

• ⭐ Industrial Grade Craftsmanship — Strict factory inspection, OEM customization available for bulk orders, manufactured in Guangdong China

• ⚠ Stop using immediately if the battery swells, leaks, overheats, emits odor or changes color — dispose at a certified electronics recycling center.

• ⚠ Use only Li-ion CC/CV dedicated chargers; never use old Ni-MH or Ni-CD chargers for this battery (overcharge fire risk).

• ⚠ Keep battery terminals away from metal objects (coins, keys, jewelry) to prevent short-circuit.

• ⚠ Avoid exposing the battery to direct sunlight, fire, or temperatures above 60 degrees C; never throw the battery into fire or water.
