Kastar 3-Pack NP-F750 NP-F770 Batteries with LTD2 USB Dual Charger

In this review the Kastar 3-Pack NP-F750 / NP-F770 battery set with the LTD2 USB dual charger is evaluated for videographers and monitor users who need reliable power on location. The bottom line: this kit is practical for shooters using Atomos and Sony-style monitor setups because it delivers high-capacity 5800mAh lithium-ion cells and flexible USB charging options, letting users top up batteries from common 5V USB sources while maintaining the ability to charge two packs simultaneously. It is a sensible, portable power solution when long runtime and multiple charging ports matter.

Key Features

• High capacity cells: Each 7.4V 5800mAh lithium-ion battery provides extended runtime for monitors such as Ninja V and Shinobi models, reducing swap frequency during shoots.
• Dual battery charging: The LTD2 USB charger can charge two batteries at once, which speeds turnarounds between takes and keeps spares ready.
• Interchangeable plate: The charger plate can be changed to fit different battery plates, so the kit adapts to multiple compatible mounts without buying new units.
• USB-powered convenience: With 5V 2-3A input and both Micro-USB and Type-C options, the charger accepts common power banks and wall adapters for on-the-go charging.
• Intelligent LED display: The charger uses LED indicators to show charging status and relative battery capacity, making it easy to see which cells are ready.
• Compact and portable: The batteries and LTD2 charger are lightweight and designed to be carried in camera bags for location production.

Who It's For

The kit is aimed at independent filmmakers, run-and-gun shooters, and small studio crews who use Atomos or compatible monitors such as Shinobi 5' or Ninja V 5' models and need extra runtime without carrying a bulky V-mount rig. It is especially useful for users who value dual charging and USB input versatility for charging from power banks, car adapters, or compact USB chargers.

Those who should look elsewhere include users who require OEM-brand batteries for manufacturer warranty alignment or larger battery ecosystems like V-mount or Gold mount systems; this kit is specifically for NP-F750 / NP-F770 style plates rather than professional plate mounts.

Pros & Cons

Pros

• High 5800mAh capacity extends monitor runtime significantly compared with smaller packs.
• Dual charging capability halves the time to replenish two batteries between shoots.
• USB input options and included Micro-USB cable make charging flexible on location.

Cons

• Not a V-mount or Gold mount solution, so it does not integrate with larger studio battery systems.
