Hi-Target A16 Survey GNSS Replacement Battery 7.4V 5200mAh

Up to 19% off
New arrival
From $85.99 USD $105.99
Shipping calculated at checkout.
Fits Hi-Target A16, TS7, V98, and iRTK5 Host Bag units; replaces OEM part number BL-6800.
7.4V 5200mAh lithium-ion cell delivers 38.48Wh to sustain continuous GNSS measurements and data logging without mid-session power loss.
Connector seats into the A16 battery slot with positive terminal forward; locking tab engages on insertion and holds firm under field vibration.
We bench-tested this pack through five full charge cycles on Hi-Target's standard charger; BMS accepted handshake immediately and held voltage steady under sustained current draw.
After installation, run a full calibration cycle through the A16 menu before field work — the instrument maps battery state during calibration, and skipping this step causes premature low-battery warnings on the first measurement session.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

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.

Hi-Target A16 / V98 / iRTK5 Series — 7.4V Li-ion Replacement Battery (BL-6800)

The BL-6800 is a 7.4V 5200mAh lithium-ion battery for Hi-Target GNSS receivers and total stations. It fits the A16, TS7, V98, and iRTK5 Host Bag. Capacity is 38.48Wh — sufficient for full field sessions without mid-day swaps.

  • A16, TS7, V98, and iRTK5 compatibility: These units share the same 7.4V battery rail, BL-6800 footprint, and BMS handshake protocol. One battery pack covers all four instruments — no pin remapping or firmware flag needed.
  • Bench tested on actual hardware: We cycled this pack through cold-start initialisation, satellite lock acquisition, and sustained RTK logging. The BMS held steady through the receiver's antenna power-up current spike without tripping into protection mode.
  • First-deployment calibration: After fitting a new pack, run a full calibration cycle through the instrument menu before heading to site. The receiver maps battery state during calibration — skipping this causes premature low-battery warnings during your first measurement session, even when the pack is at full charge.

BMS lockout after the A16 sat unused in a carry case for months

Li-ion cells self-discharge slowly in storage. If the pack drops below approximately 2.5V per cell, the BMS trips into deep-discharge lockout and the instrument won't power on — it won't even show a charging indicator. Place the battery on a compatible charger and leave it for up to 30 minutes; most BMS circuits will accept a trickle recovery charge at that threshold. Once cell voltage climbs above 3.0V per cell, normal charging resumes and the instrument will recognise the pack again.

Instrument shuts down during USB data transfer to PC

Data transfer over USB adds a second draw on top of active receiver processing — combined load can pull the battery below the BMS cutoff threshold faster than field measurement alone. This usually happens when the pack has partial charge rather than a full one. Top the battery to 100% before connecting to a PC for data offload. If shutdowns persist, check that the USB cable is data-only and not simultaneously attempting to charge the instrument from a low-output port, which can confuse the power management circuit.

Frequently Asked Questions

My Hi-Target A16 powers on fine but shuts off the moment it locks onto satellites — why?

Satellite lock acquisition triggers the antenna LNA and all tracking channels simultaneously, which creates a brief current spike. If the battery cells have aged or the pack voltage is sitting below 7.2V at rest, that spike pushes draw beyond what the BMS allows and it cuts the circuit. This isn't a firmware issue — it's the BMS protecting cells that can no longer sustain the load. Charge the pack fully and retest; if the shutdown repeats at full charge, the cells are degraded and the pack needs replacing.

The battery indicator on my V98 jumps from 60% to 15% and then back up — what's causing that?

A new cell set has a slightly different discharge curve than the depleted pack the instrument was calibrated against. The percentage display is reading voltage thresholds, and until the receiver maps the new pack's curve, the indicator miscalculates state of charge mid-session. Run two full charge-to-discharge cycles through normal field use, then let the instrument complete its battery calibration routine in the menu. After that, the percentage readout will track accurately.

The BL-6800 won't take a charge after sitting in storage — charger light stays red and never switches to green

A charger stuck on red with no progression means the pack voltage has dropped below the charger's detection threshold — typically caused by self-discharge over a long storage period. Connect the battery to the charger and leave it undisturbed for 20–30 minutes; the charger needs time to push enough trickle current to bring cell voltage up to where it registers as a valid Li-ion pack. If the light shifts to amber or begins a normal charge cycle within that window, the pack has recovered. If it stays red past 45 minutes, cell voltage is below recoverable range at approximately 2.0V per cell total.
