Philips LDX-110 Replacement Battery 14.4V 10400mAh

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

This is a 14.4V Li-ion battery rated at 10400mAh (149.76Wh), built to replace the factory pack on Philips LDX-110, LDX-120, LDX-140, and LDX-150 broadcast cameras. These cameras are used in live television and documentary production where losing power mid-take isn't an option. Voltage and connector match the OEM specification for these four models.

• LDX-110 through LDX-150 platform fit: All four LDX models in this range share the same 14.4V power rail, battery connector pinout, and BMS communication protocol. A single battery format covers the series, which is why this cell works across all four without modification.
• Bench tested on actual hardware: We ran this battery through charge and discharge cycles, monitoring BMS handshake, cell balancing, and cutoff behaviour under camera body load. The protection circuit responded correctly to both over-discharge and thermal thresholds during testing.
• First charge on location shoots: Before taking this battery onto a live set, run one complete charge cycle through the OEM Philips charger or directly in the camera body. Some LDX-series BMS systems need that first cycle inside the camera to calibrate the battery-remaining display accurately.

Why the LDX-series battery indicator reads low on a fully charged replacement cell

The LDX camera body maps battery percentage against a voltage-threshold curve stored from the OEM cell's discharge profile. A new third-party cell discharges along a slightly different curve, so the camera body initially reads the voltage against the wrong reference points. This causes the indicator to underreport charge, sometimes showing 40–50% when the cell is nearly full. After one or two full charge-discharge cycles through the camera body, the BMS recalibrates and the display tracks correctly.

The LDX-series cameras run an authentication check on the battery during startup. If the BMS in a new replacement cell hasn't completed an initial handshake with the camera body, the camera may reject the pack entirely. Remove the battery, reinsert it firmly, and attempt a power cycle. If that fails, place the battery in the OEM Philips charger until it reads fully charged — typically to 16.8V — then reinsert into the camera body.
