Olympus NC2040A22 IPLEX LX/LT Compatible Battery 10.8V 3400mAh

Olympus IPLEX LX/LT Series — 10.8V Li-ion Replacement Battery (NC2040A22)

This 10.8V, 3400mAh Li-ion battery replaces the original pack in Olympus IPLEX LX/LT and IPLEX MXII portable videoscope systems. It fits the handheld display unit that powers the insertion tube, light source, and on-screen image processing during confined-space inspections. Voltage and cell count match the OEM spec exactly — no adapter or modification required.

• IPLEX LX/LT and MXII compatibility: These models share a common battery bay, connector pinout, and BMS communication protocol. The display unit handshakes with the pack over a dedicated data line — voltage alone does not satisfy the check. This pack carries the correct cell configuration and communication response to pass that handshake without triggering a battery error on boot.
• Bench tested on actual hardware: We ran the pack through a full power cycle on an IPLEX LT unit, including probe initialisation and sustained tip articulation. The BMS held stable through the current spike at probe power-up — the point where undersized or poorly cloned cells typically trip the protection circuit and cut output.
• First deployment after storage: After installing a new pack, run a full calibration cycle through the instrument's system menu before taking it into the field. The IPLEX maps battery state during calibration — skipping this step causes the low-battery indicator to fire prematurely on the first inspection session, even with a full charge.

BMS cutoff at probe insertion tube initialisation

When the IPLEX powers on the insertion tube, the tip motor, LEDs, and image sensor all draw current simultaneously. This surge can spike 2–3A above the steady-state draw for roughly half a second. A pack with degraded cells or a conservative protection IC will read that spike as an overcurrent event and cut output immediately — the screen goes black and the unit reboots. This battery uses cells rated for the peak pulse current the IPLEX requires at probe wake-up, so the BMS does not misread initialisation as a fault condition.

Pack will not charge after sitting unused in carry case for months

Li-ion cells that self-discharge below approximately 2.5V per cell enter a deep-discharge state where most chargers refuse to begin a charge cycle — the BMS presents too low a voltage for the charger's detection threshold. The IPLEX OEM charger has a recovery mode, but it activates only if the pack voltage is still above the charger's minimum detection floor, typically around 8V for a 3S pack. If the charger shows no activity, connect the pack and leave it on charge for 20–30 minutes without interruption — some chargers need a brief trickle period to wake the BMS before switching to full charge. If the charge LED still does not activate after that window, check cell voltage directly; anything below 7.5V across the pack requires a dedicated lithium recovery charger set to 10.8V nominal before returning to the OEM charger.
