ENL-BL1703 7.4V 2000mAh Li-ion Two-way Radio Battery for HYT TC-700 / TC-780 / TC-780M / TC-710 Commercial Walkie Talkies

The ENL-BL1703 replacement battery is fully compatible with the following HYT TC series commercial two-way radio models:

✅ Faithful OEM Replacement for HYT TC-700 / TC-780 / TC-780M / TC-710 Radios
Direct replacement for HYT (Hytera) OEM part BL1703, supporting 4 professional commercial handheld models including TC-700, TC-780, TC-780M and TC-710. Plug-and-play fit, no modification required.

✅ Industrial Grade Li-ion Cell Pack with 5-Protection BMS
Premium long-cycle Li-ion cells deliver stable 7.4V output and rated 2000mAh capacity for typical 10-12 hour shift operation. Built-in smart BMS module provides over current protection (OCP), over charge protection (OVP), over discharge protection (UVP), temperature sensor and reverse polarity protection — comprehensive safeguard against field failures.

✅ Lightweight High-Energy ABS/PC Shell & Ultrasonic Welding Sealing
Robust ABS/PC composite housing with ultrasonic integrated welding sealing, golden plated brass low-resistance contacts — anti-drop, dustproof and moisture resistant. Li-ion gravimetric energy density is roughly double that of Ni-MH, so this pack delivers more runtime in a slimmer, lighter body, reducing operator fatigue during extended full-shift carry.

• ⭐ OEM BL1703 Replacement — Faithfully matches original dimensions (10.70*5.40*1.70cm), drop-in fit for all TC-700/780/780M/710 series radios without chassis modification

• ⭐ 2000mAh High Capacity, 7.4V Stable Output — Full-shift communication on a single charge, low self-discharge, no full-discharge required before recharging thanks to Li-ion chemistry

• ⭐ 5-in-1 Smart BMS Protection — Over-charge, over-discharge, over-current, temperature and reverse-polarity protections are mandatory for Li-ion safety, keeping the pack safe during daily field abuse

• ⭐ Wide Temperature Tolerance — Performs reliably across -20 degrees C to 60 degrees C working range, ideal for outdoor and industrial environments

• ⭐ Industrial Craftsmanship & Warranty — Manufactured under strict aging test procedure, OEM private label and bulk customization available, 12-month full quality warranty

• ⚠ Do not disassemble, puncture, crush or modify the battery housing — internal cell damage may cause electrolyte leakage, overheating or fire. Stop using the battery immediately if you notice swelling, unusual heat, odor or deformation, and move it to a safe non-flammable area away from combustibles.

• ⚠ Keep battery terminals away from metal objects such as coins, keys and jewelry to prevent accidental short-circuit. Do not expose the battery to high temperature above 60 degrees C, direct sunlight or open flame for extended periods.

• ⚠ Only charge with a Li-ion compatible CC/CV (constant current / constant voltage) charger rated for 8.4V charging voltage. Do NOT use a Ni-CD / Ni-MH charger on this Li-ion battery — the cutoff logic is completely different and may cause overcharge, overheating or permanent damage.

• ⚠ Do not store the battery fully discharged for long periods. For long-term storage, keep the pack at approximately 40-60% charge in a cool dry place and recharge every 3 months. This Li-ion battery contains regulated lithium cells — do not dispose of it with household waste; return the spent battery to an authorized battery recycling collection point in compliance with local regulations.
