Kastar 3-Pack NP-F750 NP-F770 Battery and LTD2 USB Charger - Reliable

In this review the Kastar 3-Pack NP-F750 / NP-F770 battery set with the LTD2 USB dual charger is evaluated for videographers and photographers who rely on Lilliput and similar field monitors. The bottom line: this kit is for shooters who need multiple high-capacity spares and simple, portable charging on location. The combination of three 5800mAh lithium-ion batteries and a USB charger that can handle two batteries at once makes it an efficient, compact power solution for extended shoots.

Key Features

• High capacity batteries: Each 5800mAh lithium-ion cell delivers extended runtime for 7.4V compatible monitors, reducing swap frequency during long takes.
• Dual battery charger: The LTD2 USB charger can charge two batteries simultaneously, saving time when preparing multiple spares.
• Flexible input options: Micro-USB and Type-C inputs let users charge from power banks, USB wall adapters, or camera rigs for on-the-go convenience.
• Adjustable plate design: The charger accepts changeable plates to accommodate different battery plates, increasing compatibility with camera accessories.
• Visible charge indicators: Intelligent LED display shows charging progress and battery capacity so users can monitor readiness at a glance.
• Compact and portable: The charger runs from a 5V 2-3A input and packs light for field work, fitting easily into a camera bag without extra bulk.

Who It's For

This kit is well suited for independent filmmakers, run-and-gun shooters and small production crews who use Lilliput A7S, H7 series, Q7, A11 or A12 monitors and need multiple spares for full-day shoots. The high capacity batteries and USB charger are particularly helpful for locations without AC power where USB power banks are the primary source.

Those who should look elsewhere include users who require OEM batteries with branded warranties from monitor manufacturers or productions that need hot-swap V-mount solutions; the Kastar pack is a compact, consumer-grade alternative rather than a studio-grade battery system.
