FanVision K-IVT-300-GD-B Compatible Battery 3.6V 3600mAh

FanVision K-IVT-300-GD-B — 3.6V Li-ion Replacement Battery (K-ABC-30P-KT-B)

This 3.6V Li-ion battery replaces the original pack in the FanVision K-IVT-300-GD-B portable DVB-T digital television receiver. Capacity is 3600mAh (12.96Wh), matching the original specification. It fits the physical battery bay and connector of the K-IVT-300-GD-B directly.

• K-IVT-300-GD-B compatibility: The K-IVT-300-GD-B uses a single-cell Li-ion pack at 3.6V nominal. This battery matches that voltage rail, physical footprint at 108.30 × 36.06 × 12.00mm, and the OEM connector orientation. No modification needed.
• Bench tested on actual hardware: We cycled this cell through the K-IVT-300-GD-B's charge circuit and confirmed the BMS accepted charge termination correctly. The protection circuit tripped at the expected low-voltage cutoff without locking the device into a fault state.
• Channel memory after power removal: The K-IVT-300-GD-B stores its channel list in volatile memory. Any full power interruption — including a battery swap — clears that list. Run a full DVB-T channel scan immediately after fitting this battery before attempting to watch live TV.

Reception breaking up at low battery on the K-IVT-300-GD-B

The DVB-T tuner in the K-IVT-300-GD-B requires stable voltage to maintain full RF front-end sensitivity. As a degraded or partially discharged Li-ion cell sags below roughly 3.4V under the combined load of the LCD and decoder, the tuner's sensitivity drops and weak multiplex signals become unreliable. This shows up as pixelation or outright signal loss on fringe channels before the device shows any low-battery warning. Fitting a fresh cell at full charge restores the tuner to its rated sensitivity threshold.

Device powers on but finds zero channels during scan

A full channel scan on the K-IVT-300-GD-B draws more current than passive standby — the tuner, decoder, and display all run simultaneously. If the battery voltage sits below approximately 3.5V at the start of a scan, the tuner may not reach minimum operating sensitivity and will return no results even in strong signal areas. This is commonly misread as an aerial or regional coverage fault. Charge the battery to full first, then re-run the scan from the device's setup menu.
