HYT BL2006 DMR PD-702 Replacement Battery 7.4V 2000mAh

Up to 20% off
New arrival
From $43.99 USD $54.99
Shipping calculated at checkout.
Fits HYT DMR PD-702, PD-782, and PD70X series radios replacing OEM part BL2006, BL2006Li, BL2008, BL2503, BL3001.
Delivers 7.4V at 2000mAh capacity for sustained transmission cycles without voltage sag during extended shifts.
Connector mates flush to the radio battery slot with positive terminal forward and locking tab seated fully into the radio frame.
We bench-tested this cell on a PD-702 dock charger; BMS accepted handshake on first insertion and held stable voltage under full PTT load.
If the charger dock shows a fault LED after inserting this battery, remove it, wipe the gold contact strip on the radio 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, 2000mAh Li-ion replacement battery for the HYT DMR PD-702 and DMR PD-782 portable two-way radios. It also fits the broader PD70X and PD70XG families across more than 60 compatible models. OEM part numbers covered include BL2006, BL2006Li, BL2008, BL2503, and BL3001.

  • PD70X platform coverage: The PD-702, PD-782, PD70X, and PD70XG share the same 7.4V voltage rail, connector footprint, and BMS handshake protocol — which is why a single pack covers the full family without modification or adapters.
  • Bench tested on actual hardware: We ran this pack on a PD-702 under simulated PTT cycles. The BMS handled repeated transmit-current spikes without tripping into protective cutoff, and the voltage held steady across the discharge curve at rated load.
  • First-insertion contact check: If the charger dock shows a fault LED 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 initiate the BMS handshake before charging begins.

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

The PD-702 draws a short high-current spike the moment PTT is pressed to bring the RF stage up to full output power. A new pack shipped at storage voltage — typically around 3.7V per cell — has a higher internal impedance than a fully charged cell. If the BMS sees the voltage dip cross its undervoltage threshold during that spike, it trips into protective cutoff and kills the transmission. Fully charge the pack to 8.4V before first use to lower cell impedance and prevent the BMS from misreading a load spike as a fault condition.

Bar indicator showing one fewer bar than expected on a new pack

The PD-702 uses a voltage-threshold bar indicator — each bar maps to a specific voltage band, not a capacity percentage. A new pack at storage voltage sits in a lower band than a fully charged one, so the display shows one or two fewer bars even though the pack is not depleted. This is not a fault with the cell or the radio. Charge the pack fully to 8.4V, then insert it — the bar indicator will reflect the correct charge state within one full charge-discharge cycle.

Frequently Asked Questions

The charger dock blinks a fault LED the moment I insert the new BL2006 — it never starts charging. What's wrong?

The HYT dock checks the BMS contact signal before it begins a charge cycle — if the gold contact strip on the pack or dock is dirty or slightly misaligned, the handshake fails and the dock throws a fault LED. Remove the pack, wipe both contact strips with a dry cloth, and reseat with firm downward pressure until you feel the latch click. If the fault clears, the dock will begin charging normally within a few seconds; if it persists, verify the pack voltage with a multimeter — a reading below 6.0V means the cell has dropped below the dock's acceptance threshold and needs a recovery charge from a bench charger first.

My PD-702 drops to reduced TX power partway through a long shift — the radio is still on, but the signal weakens noticeably. Is the battery causing this?

Yes — this is voltage sag under sustained RF output, not a radio fault. As the pack discharges, cell voltage drops, and the PD-702's power management steps the transmitter down when voltage falls below the threshold for full RF output. It is a protective measure to keep the radio operational at reduced power rather than cutting off entirely. To push the threshold back, keep the pack charged above 7.8V at the start of each shift — below that, sag under TX load becomes significant enough to trigger the power-reduction step.

The new pack was sitting unused for three months and now the charger won't recognise it at all — no LEDs, no charge cycle starts. Can it be recovered?

Extended storage causes Li-ion cells to self-discharge below the voltage floor the HYT dock will accept — typically the dock ignores any pack presenting below roughly 6.0V. The BMS has also likely entered a low-voltage lockout state. Use a bench charger with a Li-ion recovery or boost mode to bring the pack up to at least 6.5V at a low current (0.1A or less), then transfer it to the HYT dock — once the pack voltage is above the dock's acceptance threshold, the dock will recognise the BMS handshake and begin a normal charge cycle.
