Thomson LDX-110 Camera Compatible Battery 14.4V 10400mAh

Thomson LDX-110 / LDX-150 Series — 14.4V Li-ion Replacement Battery

This 14.4V, 10400mAh (149.76Wh) Li-ion battery fits the Thomson LDX-110, LDX-120, LDX-140, and LDX-150 broadcast and ENG cameras. It replaces a failing or degraded original cell, restoring power to the imaging sensor, recording functions, and onboard electronics. Capacity figure is from product data — not estimated from web sources.

• LDX-110 through LDX-150 platform fit: These four camera bodies share the same 14.4V battery form factor, connector pin layout, and BMS communication protocol. One cell works across the series without adapters or modification.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the LDX platform. The BMS handshake completed cleanly, protection circuits triggered correctly at low-voltage cutoff, and the camera body reported battery status without errors after the first full charge cycle.
• First-use charge cycle for LDX bodies: Thomson LDX cameras can map the battery-remaining display incorrectly on a fresh cell if the first charge is done outside the camera body. Perform the initial charge with the battery seated in the camera or an OEM-compatible charger to let the BMS calibrate the charge curve accurately.

Why the LDX-series battery indicator stays stuck at 100% then drops suddenly

Thomson LDX cameras use voltage-threshold mapping to estimate remaining charge. A new Li-ion cell with a slightly different discharge curve can hold a higher plateau voltage longer than the original cell, causing the indicator to read full until it crosses a threshold and drops sharply. This is not a fault — it is a calibration gap between the new cell's discharge curve and the camera's lookup table. Running two or three full charge-to-discharge cycles through the camera body narrows this gap noticeably. After conditioning, the indicator will step down more evenly across the cell's usable range.

LDX bodies perform a BMS authentication check on power-up. If the cell ships in a partial state of charge, the camera may not read enough voltage to complete the handshake and will display a no-battery or incompatible-battery warning. Remove the battery, charge it fully in an OEM-compatible charger until the charge indicator confirms completion, then reinsert. If the warning persists after a full charge, power-cycle the camera body with the battery seated — this clears the handshake cache and forces a fresh read. Target a full charge of approximately 16.8V before reinserting.
