Kastar NP-F750/NP-F770 4-Pack Batteries with LTD2 USB Charger

Our review finds the Kastar 4-Pack NP-F750 / NP-F770 batteries with the LTD2 USB charger aimed at video creators who need reliable, long runtime power for monitor rigs. The single biggest reason to buy is straightforward: a set of four 5800mAh lithium-ion packs plus a compact dual USB charger that can top two batteries simultaneously makes it easy to keep Atomos-compatible monitors running during long shoots. The package balances capacity, portability and flexible charging so it fits field shooters who prefer swap-and-go battery systems.

Key Features

• High capacity cells: Each 5800mAh lithium-ion battery provides extended run time for monitors such as Ninja V and Shinobi, reducing battery swaps on location.
• Dual battery charging: The LTD2 USB charger charges two batteries at once, which speeds turnaround when multiple batteries are in use.
• Interchangeable plate: The charger plate can be changed to accept different battery types, adding versatility for mixed rigs.
• USB power input: With Micro-USB and Type-C input and a 5V 2-3A 15W requirement, the charger can be powered from common USB battery banks or wall adapters for field convenience.
• Intelligent LED display: The LED indicators show charging status and relative battery capacity so you can judge readiness at a glance.
• Compact and portable: The kit is easy to carry in a camera bag and includes a Micro USB cable to get started immediately.

Who It's For

The kit is best for independent filmmakers, run-and-gun videographers and monitor-equipped camera operators who use Atomos Ninja and Shinobi series monitors and need multiple spare batteries. Its 5800mAh cells suit users who prioritize longer on-camera time without bulky external power solutions.

Those who should look elsewhere include crews that require hot-swappable V-mount or gold mount solutions or users with entirely different battery mounts; this set is specifically for NP-F750/NP-F770-style devices and USB-charged convenience rather than professional studio charging racks.
