HYT BL2006 DMR PD-702 Replacement Battery 7.4V 2600mAh

Up to 19% off
New arrival
From $49.99 USD $61.99
Shipping calculated at checkout.
Fits HYT DMR PD-702, PD-782, and PD70X series; replaces OEM BL2006, BL2006Li, BL2008, BL2503, BL3001.
This 7.4V 2600mAh Li-ion pack delivers full transmit power without voltage sag during sustained RF output.
Connector slides straight into the radio's battery slot with a positive-to-radio-top orientation; locking tab seats flush.
We bench-tested this cell on a PD-702 PTT cycle — BMS accepted the handshake on first dock insertion and held voltage stable under transmit load.
If the charger dock shows a fault LED on first insertion, remove the battery, wipe the gold contact strip with a dry cloth, and reseat firmly — the HYT platform requires a clean contact cycle to accept the new BMS handshake before charging begins.

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

HYT DMR PD-702 / PD-782 Series — 7.4V Li-ion Replacement Battery (BL2006)

This is a 7.4V, 2600mAh Li-ion battery for the HYT DMR PD-702, DMR PD-782, PD70X, and PD70XG series digital mobile radios. It replaces OEM part numbers BL2006, BL2006Li, BL2008, BL2503, and BL3001. If your original pack is no longer holding charge across a full shift, this is the direct swap.

  • PD-700 series platform compatibility: The PD-702, PD-782, PD70X, and PD70XG share the same 7.4V battery rail, connector pinout, and BMS handshake protocol — which is why a single pack covers all these models. Swapping between them does not require any firmware or charger change.
  • Bench tested on actual hardware: We ran this pack through a full charge cycle on a HYT drop-in dock and cycled PTT transmit loads repeatedly. The BMS held steady under the current spike and did not trip into overcurrent protection during sustained transmit bursts.
  • First insertion into the charger dock: If the dock LED shows a fault on first insertion, remove the pack, wipe the gold contact strip with a dry cloth, and reseat firmly. The HYT platform requires a clean contact cycle to complete the BMS handshake before charging begins — this is not a defective pack.

Why the PD-702 cuts out mid-transmission on a new BL2006

A new Li-ion cell ships at storage voltage — typically 3.6–3.7V per cell, not full charge. When you key up on a fresh-from-box pack, the transmit current spike can pull cell voltage below the BMS cutoff threshold before the pack has been fully charged. The radio interprets this as a low-battery condition and drops TX. Charge the pack fully before first operational use — the dock should show green before you key up for the first time.

Bar indicator showing one fewer bar than expected after a full charge cycle

HYT radios use a simple voltage-threshold system to drive the bar indicator — each bar corresponds to a voltage band. A new cell that has only completed one charge cycle may rest at a slightly lower open-circuit voltage than a conditioned pack, which shifts the reading down by one bar. Run two full charge-and-use cycles and the resting voltage will stabilise at the correct level. After the second cycle, a full charge should read the same bar count as the original OEM pack — if it still reads low, check that the dock contacts are clean and seating fully against the pack's gold strip.

Frequently Asked Questions

My HYT PD-702 drops to reduced transmit power mid-shift on the new BL2006 — is the pack faulty?

This is voltage sag under sustained RF output, not a faulty pack. During long PTT transmissions, current draw is high enough to pull cell voltage down temporarily, and the radio responds by reducing TX power to stay within its operating window. It happens most on packs that haven't been fully conditioned yet. Run two complete charge cycles and avoid keying up for extended periods until the cells have stabilised — after conditioning, sag under normal PTT use drops significantly.

The charger dock LED is blinking and never clears after I insert the new BL2006 — what's happening?

The dock is rejecting the BMS handshake because the pack arrived below the dock's acceptance voltage threshold. Remove the pack, wipe the gold contact strip with a dry cloth, and reseat it firmly — a poor contact is the most common cause. If the fault LED persists, leave the pack in the dock for 10–15 minutes without removing it; some HYT chargers require the pack to sit at rest before they attempt re-initialisation. The dock should transition to a steady charge LED once it reads the pack voltage above roughly 6.0V.

The PD-702 powers on fine but cuts off completely when I press PTT — no warning, just dead radio.

This is a BMS overcurrent trip caused by the transmit current spike hitting the pack's protection threshold. It typically happens when the pack is at storage voltage rather than full charge — the cell voltage is low enough that the spike pushes instantaneous current above the BMS limit. The fix is straightforward: charge the pack fully before use, then key up. A full charge brings resting cell voltage to approximately 4.1–4.2V per cell, which gives enough headroom for the PTT spike to clear the BMS threshold without tripping.
