Kastar NP-F960 NP-F970 Battery 2-Pack - High Capacity Replacement

In this review the Kastar NP-F960 / NP-F970 Battery 2-Pack is judged as a straightforward, high-capacity replacement for LED video lights that use the common Sony-style battery plate. The bottom line: this pack is for video creators and photographers who need noticeably longer runtime from lights such as the YongNuo YN300-III and YN600 series without paying for OEM batteries. The reviewer found the batteries deliver extended run time, built-in safety circuitry, and a two-pack convenience that reduces downtime on shoots.

Key Features

• High capacity: The 8700mAh rating provides significantly longer continuous power for LED panels, reducing battery swaps during shoots.
• Compatibility: Designed to replace NP-F960 and NP-F970 style cells and fit popular LED video lights including YongNuo and many Neewer models.
• Safety protections: Built-in over-charge, over-discharge, over-voltage, over-current, and over-heating protection helps prevent damage to the pack and the light.
• Certified cells: Lithium-ion cells meet UL1642 and CE standards, giving reassurance on safety and manufacturing oversight.
• Cost effective: Shipping two batteries in the package saves money and time compared with frequent single replacements or low-capacity alternatives.
• Easy swap: The NP-F form factor makes it simple to swap batteries mid-shoot without changing mounts or adapters.

Who It's For

The Kastar 2-pack is aimed at independent videographers, content creators, and studio photographers who rely on continuous LED lighting for interviews, product shoots, or run-and-gun production and want longer runtime than typical lower-capacity replacements. It is especially useful for users of YongNuo YN300-III, YN600, and many Neewer LED panels that accept NP-F type batteries.

Those who should look elsewhere include photographers using lights that require proprietary or hardwired batteries rather than NP-F style, or professionals who prefer factory OEM packs with brand warranty service. If an absolute minimum weight is critical, the higher capacity cells can be slightly heavier than slim alternatives.

Pros & Cons

Pros

• Long run time from the 8700mAh cells reduces interruptions during shoots.
