SWIT LB-SU90C SONY BP-U Series Battery Pack

The SWIT LB-SU90C is a 90Wh lithium-ion battery pack engineered as a drop-in Sony BP-U replacement battery for broadcast and cinema camcorders. Rated at 14.4V nominal with a built-in D-Tap output and a 45W USB-C port, the LB-SU90C powers Sony PXW-FX9, PXW-FS7 / FS7 II, PMW-EX1R and FX6 rigs while charging monitors, wireless kits and laptops on set. For BD videographers sourcing professional camcorder power, Momi Enterprise stocks the LB-SU90C alongside a full range of Battery & Power Solutions at our Dhaka showroom.

Key Specifications

Compatible Sony Cameras (BP-U Mount)

The LB-SU90C is a direct replacement for Sony BP-U batteries. Confirmed compatible Sony bodies stocked or supported by Momi Enterprise:

• Sony PXW-FX9 (full-frame XDCAM)
• Sony PXW-FS7 and PXW-FS7 II (Super 35 XDCAM)
• Sony PXW-Z450 (shoulder-mount XDCAM)
• Sony PMW-EX1R and PMW-EX3 (HD camcorders)
• Sony PMW-F5 and PMW-F55 (CineAlta)
• Sony FX6 full-frame cinema camera

For the full-frame cinema workflow, pair the LB-SU90C with the Sony FX6 Full-Frame Cinema Camera. For XDCAM shoulder bodies, see the Sony PXW-Z280 4K XDCAM camcorder or the lighter PXW-Z190 4K XDCAM camcorder. Note: the Sony PXW-Z90V uses the NP-FV series — the LB-SU90C does not fit the Z90V. It is listed here only as a companion Sony body in our catalog.

How to Use the SWIT LB-SU90C

Setup and first charge

Unbox the LB-SU90C and give it a full initial top-up before the first shoot. The pack takes charge from any standard Sony BP-U charger, and can also sip power through the 45W USB-C PD port when you only have a laptop brick handy. For multi-pack crews, a dedicated multi-slot charger is faster and safer — pair with the SWIT S-3822A Charger for a single-bay broadcast solution, or the SWIT LC-D421 4-Channel Multi-Type DV Charger if you rotate 3 or 4 packs on a long documentary day.

Powering a Sony FS7 or FX9 rig

Slot the LB-SU90C into the BP-U bay as you would a genuine Sony pack. The camera's battery-level readout reads the LB-SU90C's fuel gauge directly — no calibration needed. On an FS7 II with no accessories attached, a single 90Wh pack runs the camera for a meaningful portion of a shoot day; add an on-camera monitor or wireless receiver via D-Tap and runtime drops proportionally.

Powering accessories via D-Tap and USB-C

Use the D-Tap output at 14.4V DC for on-camera monitors, wireless audio receivers, LED top-lights and teleprompters. Use the 45W USB-C PD port for laptops, phones, tablets and USB-C monitors on location — handy when DITs need to dump cards without mains power. Check every D-Tap cable for correct polarity before plugging in a third-party accessory.

How It Compares

Three common choices for BD videographers powering a BP-U body: the SWIT LB-SU90C (this product), a genuine Sony BP-U90, and the higher-capacity SWIT LB-SU98D. Real-world differences:

If you run a heavy rig (wireless + two monitors + LED) and want longer runtime in a single pack, step up to the 98Wh LB-SU98D — still airline-safe. If you want a second brand on the shelf for redundancy, the Dynacore DS-U95B Li-Ion Battery (Sony BPU-Series) is a common BD-market peer. For multi-brand charger compatibility, consider the Dynacore DDBC-TP Dual Charger.

Care and Storage

• Store packs at roughly half charge when not shooting for more than two weeks — extends cell life.
• Keep away from direct sunlight, dashboards and any heat source above 45°C.
• Dhaka humidity is real — if the pack will sit in a case for weeks, add silica gel and keep terminals covered.
• Never drop, puncture or attempt to open the cell — the protection circuit is one-way and will disable the pack if tripped.
• Check the 4-LED gauge before every shoot and top up any pack sitting below 50%.
• Use matched chargers — a quality charger from our Chargers & Adapters range protects the cell through its full life.

Frequently Asked Questions

What is the capacity of the SWIT LB-SU90C?

The SWIT LB-SU90C is a 90Wh / 6.2Ah lithium-ion pack at 14.4V nominal. That is marginally higher than Sony's own BP-U90 and stays under the 100Wh airline carry-on threshold, so you can fly with it for international shoots.

Is the SWIT LB-SU90C compatible with the Sony PXW-FX9?

Yes. The LB-SU90C is a drop-in replacement for Sony BP-U batteries and works on the Sony FX6, PXW-FX9, PXW-FS7 / FS7 II, PXW-Z450, PMW-EX1R, PMW-EX3 and PMW-F5 / F55. Mount it into the BP-U bay exactly as you would a genuine Sony pack — the camera's fuel gauge reads the LB-SU90C's level directly.

Does the SWIT LB-SU90C have a D-Tap output?

Yes — the LB-SU90C includes a 14.4V D-Tap output on the top panel. Use it to power an on-camera monitor, wireless audio receiver, LED top-light, teleprompter or any accessory that accepts 14.4V D-Tap input. Confirm polarity on your accessory cable before connecting.

Can I charge accessories through the USB-C port?

Yes. The USB-C port is a 45W PD port, so it can run or charge a laptop, phone, tablet or USB-C monitor on location. It also accepts 45W USB-C PD input if you only have a laptop brick to top up the pack — handy when you are away from a dedicated SWIT charger.

How long does the SWIT LB-SU90C last on a Sony FS7?

Runtime depends on the rig. On an FS7 or FS7 II recording internally with no accessories, a single 90Wh pack will carry you through a meaningful portion of a shoot day. Once you add a monitor, wireless receiver and an on-camera LED via D-Tap, runtime drops proportionally — plan on two packs minimum for any paid shoot and three for a full-day documentary.

SWIT LB-SU90C কি original Sony battery-র বিকল্প হিসেবে safe?

হ্যাঁ, নিরাপদ। SWIT হচ্ছে একটি established broadcast battery brand, এবং LB-SU90C পুরো protection suite (over-current, over-voltage, over-discharge, short-circuit, over-temperature) নিয়ে আসে। Drop-in BP-U compatibility, plus extra D-Tap এবং USB-C — যেটা genuine Sony BP-U90-এ নেই। তাই অনেক BD videographer এটাকে genuine Sony-র upgrade হিসেবে use করেন।

Where can I buy the SWIT LB-SU90C in Dhaka?

Momi Enterprise-এ পাবেন — ঠিকানা 83/A, Bangabandhu National Stadium Market, Dhaka। সারা বাংলাদেশে ডেলিভারি available, COD accepted। Online order করলে Dhaka-র ভেতরে দ্রুত pickup বা delivery, ঢাকার বাইরে nationwide courier চলে। Momi Enterprise Bangladesh-এ professional broadcast equipment-এর trusted supplier।

Is the SWIT LB-SU90C airline / carry-on safe?

Yes — the LB-SU90C is rated at 90Wh, under the 100Wh IATA carry-on limit for lithium-ion batteries. Pack it in your carry-on (not checked baggage), protect the terminals from short-circuiting, and carry the manufacturer label visible. Always check your specific airline's policy before travel.

How many SWIT LB-SU90C batteries do I need for a full day shoot?

For a bare FS7 or FX9 recording internally, two packs cover a half-day; three give you a comfortable full day. Add a monitor, wireless receiver or LED and the D-Tap load pushes you to four packs for a full documentary day. Most BD wedding and event crews carry three to four LB-SU90C packs with a multi-slot charger in the truck.

What is the warranty on the SWIT LB-SU90C in Bangladesh?

Every unit ships with SWIT importer warranty applicable through Momi Enterprise — bring the pack and your purchase invoice to our Dhaka counter for assessment. Claims are processed per SWIT's standard battery warranty terms. Physical damage, punctures and third-party modifications are not covered.
