Xsarius Satmeter HD Pro 2 7.4V 3000mAh Li-Polymer Compatible Battery

Xsarius Satmeter HD Pro 2 — 7.4V Li-Polymer Replacement Battery

This 7.4V 3000mAh Li-Polymer pack replaces the internal battery in the Xsarius Satmeter HD Pro 2 portable satellite signal meter. It fits technicians who use the meter in the field to measure signal strength, quality, and frequency during satellite system installation and fault-finding. Capacity is 3000mAh (22.2Wh), matching the original cell specification.

• Satmeter HD Pro 2 platform fit: The HD Pro 2 uses a slim Li-Polymer cell at 7.4V nominal to power its tuner front-end, display backlight, and signal-processing board from a single regulated rail. This pack shares the same 88.20 × 64.70 × 8.90mm footprint and voltage, so the power management circuit sees no difference at initialisation.
• Bench tested on actual hardware: We cycled this pack through the Satmeter HD Pro 2's full boot and tuner lock sequence. The BMS held voltage through the tuner initialisation spike and sustained draw during extended signal scanning without triggering an over-current cutoff.
• Post-install calibration cycle: After fitting this pack, run a full calibration cycle through the instrument's system menu before heading to a job. The Satmeter HD Pro 2 maps battery state during calibration, and skipping this step causes premature low-battery warnings during your first measurement session in the field.

BMS cutoff when the tuner module powers up cold

The Satmeter HD Pro 2 tuner front-end draws a short inrush current when it initialises from cold — this is normal, but a degraded or deeply discharged cell can trigger the BMS over-current threshold right at that moment, causing an immediate shutdown that looks like a dead battery. This pack's BMS is rated to handle the inrush without tripping. If you see an immediate shutdown on power-up with a new pack, let the meter charge to at least 7.8V before attempting boot — a pack sitting below recovery voltage will trip the same cutoff.

Pack will not charge after the meter sat unused for months

Li-Polymer cells that sit discharged for an extended period drop below the BMS recovery threshold — typically around 6.0V for a 7.4V nominal pack — and the charger circuit in the meter sees the pack as a fault rather than a depleted cell. Connect the meter to USB power and leave it for 30–45 minutes without attempting to power it on; the charger will trickle current into the cell until voltage climbs above the reinitialisation threshold. Once the meter's charge indicator becomes active, proceed with a normal charge cycle to 8.4V before first use.
